Could Not Detect Network on deploy.js - WSL & Ganache

[Equious]

const provider = new ethers.providers.JsonRpcProvider(
    "HTTP://127.0.0.1:8545"
  );

Error:

reason: 'could not detect network',
  code: 'NETWORK_ERROR',
  event: 'noNetwork'

My Ganache UI is running. I assume this has something to do with WSL/Ubuntu .. I've never used the linux side of anything before >.>. I tried setting my Host Name to 0.0.0.0 (All Interfaces) and reflecting that in my script, but there was no change.

[RevanthGundala]

I'm not sure if this would help, but maybe you can try making the HTTP lower case -> http. Sometimes there can be errors with capitalization.

[Equious]

Hmm, it shouldn't matter, but I have tried both to no avail. Appreciate the reply!

[kasae13]

Because you use WSL but Ganache UI opened is on Windows. You need to install ganache on WSL first then run the ganache server on WSL after that you can deploy on network. Here is the steps.

1. Run npm install ganache on Terminal. Check if it is install correctly by run ganache --version
2. Run ganache on terminal, you will see many information include private keys and RPC showing. Put one of private key and RPC in deploy.js
3. Open new terminal and run node deploy.js
4. Check your ganache terminal again and you should see transaction appear.

My ganache UI is not working. I am using ganache terminal but every time I use yarn run ganache the transaction resets and I get new wallets. Is there a way to check previous transactions and not get new wallets?

@BlueAdmiral Just type yarn run ganache in terminal, replace private key and RPC Server in the contract from the available wallets and open new terminal(you could see a + button in the top right corner of existing terminal) and run deploy.js. It should work.

thank you ! it really works !

[OceanHL]

Thank you, this question has been bothering me for a long time

[FreezingM]

Thank you for your help! I tried a lot of things and it still didn't work until I saw your solution to solve the problem :)

[azank-hyder]

This solution partially worked for me. After running yarn run ganache I get an error stating "This version of µWS is not compatible with your Node.js build". However after this error it still manages to deploy accounts with fake ether. What version of node.js should I use for this to work, I realize this issue was raised 2 years ago. Should I change my node.js version or keep it up to date while using an alternative method to connect through WSL?

[vish9812]

Actually if you're running WSL 2, you can install & run Ganache(GUI) natively. And can simply use it; as it's actually installed on the Linux.

Steps to run:

1. Download the latest *.AppImage from https://github.com/trufflesuite/ganache-ui/releases

• wget https://github.com/trufflesuite/ganache-ui/releases/download/v2.5.4/ganache-2.5.4-linux-x86_64.AppImage

2. Make it executable chmod +x ganache-2.5.4-linux-x86_64.AppImage
3. Run it ./ganache-2.5.4-linux-x86_64.AppImage

Voila! 🥳

[vish9812]

No idea. But make sure you've uninstalled any other Ganache, then try to install this.

[Ayush10]

trying this, but getting tmp/.mount_ganach8Dr7O1/Ganache: error while loading shared libraries: libXcursor.so.1: cannot open shared object file: No such file or directory after step 3. Any suggestions? :(

Hi if you are still having issues with this then there is simple way to do it. You just need to install the name of the library. I did a bit of digging and discovered that Windows Subsystem for Linux doesn't come with the required libraries to run an executable. I had to download 7-8 libraries and got to fix the issue.

What libraries did you install?

[drpc0101]

this does work! but it does not work for those who have the WSL1 version and they must have it in WSL2 and reinstall the linux operating system that is running it again

awesome...was looking for something like this

[mariusdique]

Thanks mate but it tells me the invitation is invalid. In my case Itried with the npm and also the yarn way. But I am not able to see the ganache version. (ganache: command not found)

[yatinkhandelwal]

same issue with me. How to resolve this?

[ashrth]

If you are using yarn, try "yarn run ganache"

[daniyaniazi]

Thanksyarn run ganacheworks as ganache was not working

@Equious could you send me the ds link again please?

[chongdashu]

You have to run ganache as “yarn run ganache” in the terminal.

loool thanks mate! this actually just saved me <3

[0xAritra]

If it gets stuck on deploying after changing the hostname in Ganache UI (like this and this), then you have to allow the connection for Ganache in Windows Defender Firewall with Advanced Security.

• Select Inbound Rules.
• Select Ganache, right-click and go to Properties.
• Allow the connection and Apply.
• Repeat for the rest, if any.

[azhen1311]

Thank you !!!!

[TravCrypto]

Well, I literally tried each one of these solutions multiple times (over 2+ hours) and was never able to actually run node deploy.js successfully.

I imagine it was user error on my part, and I appreciate everyone's attempt at explaining the solution.

I'm going to try and keep moving forward with the course.

[hrushigawade4]

I have same problem when you change server setting wsl then your ganache rpc server also changed so this error is coming so replace in your deploy js

eg in my case

const provider = new ethers.providers.JsonRpcProvider(
"http://172.19.112.1:7545" //you get this in your ganache gui
);

[shivnix]

Yeh changing the setting of HOSTNAME from Loopback Pseudo-Interface 1 to vEthernet(WSL) will change your RCP server URL, after replacing this new URL the node deploy.js command gonna work successfully.

Thanks!

[uditrajawat]

use hostname as -Ethernet WSL
and check your windows defender inbound rules=>allow;
it will work for sure.

[BT5ZH]

I use the same way like @hrushigawade24 , it can connect the ganache,
but still get another error

const provider = new ethers.JsonRpcProvider("http://172.25.32.1:7545");
  const wallet = new ethers.Wallet(
    "0x1b7c58ec21da243cf0bc51a6868c235d7441d6ba0ed2e59a3dbe217c05fc1c7c",
    provider
  );

  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy();
  console.log(contract);

I got another problem like this below, and I have no idea about it

Error: missing revert data (action="estimateGas"

Following up, this is what worked for me:
I was using Windows 11, WSL2, and GanacheUI installed in windows. When running node deploy.js, I was getting the following error:

reason: 'could not detect network',
  code: 'NETWORK_ERROR',
  event: 'noNetwork'

Must be some kind of firewall issue, but I didn't want to debug the networking, and instead just ran a simple command to run ganache in the terminal of VS code. In the top right corner of the terminal section, click the little plus icon to open a new terminal. Then enter the following:

yarn add ganache
yarn run ganache

copy the local IP address that's printed at the very bottom: "RPC Listening on 127.0.0.1:4444"
Paste that IP into the deploy.js:

const provider = new ethers.providers.JsonRpcProvider(
    "http://127.0.0.1:4444"
  );

save it, then switch back to the other terminal window that isn't running ganache

node deploy.js

Thanks to the other folks in this thread!

[Fushiguro19]

best answer :)

[ADK0010]

Life Saver, thank you !!!!!!!!!!!!!!!

[ghost]

Thank you so much! It's worked

[NakeshTewari]

It worked!!!!!!!

[shawakash]

I appreciate you.
You just saved me from giving up this part.
Thank you very much! 👍

[LetsBuildAndCreate]

This is what worked for me 👍

OPTION 1: If you want to install & run Ganache on your WSL itself👇

1. Install Ganache on WSL
   yarn add ganache

2. Run Ganache
   yarn run ganache

3. Copy the RPC URL (127.0.0.1:8545) from the bottom of the terminal screen that says RPC listening on 127.0.0.1:8545
   & paste it in the ethers.js JsonRpcProvider( ) function parameter.

4. Also copy any Private key on scrolling up the Terminal Screen & paste it in the ethers.js Wallet( ) function parameter.

5. Now let this terminal run in the background, since we want our Ganache server to be running.
   So open a new terminal & run the deploy.js file by running the below command:
   node deploy.js

OPTION 2: If you want to run Ganache on your Windows ( if you have already installed Ganache on Windows )👇

1. Go to Settings ( Gear Icon ) on the Top Right hand Corner of Ganache Windows GUI.
   Move over to the Server tab and Change the HOSTNAME to WSL ( Mine worked for VirtualBox & WiFi too )
   Port Number & Network ID can be LEFT UNHARMED.

2. Click on Save & Restart at the top right hand corner of the UI.

3. Now Copy the RPC URL from the RPC SERVER and paste it in the ethers.js JsonRpcProvider( ) function parameter.

4. Also Copy any Private Key and paste it in the ethers.js Wallet( ) function parameter.

5. IMPORTANT STEP ( Firewall Settings ) :
   Go to Windows Defender Firewall with Advanced Security on your Windows.
   Click on Inbound Rules & Search for Ganache
   Right click on Ganache & Go to Properties.
   Then Check the CheckBox that says Allow the connection & Click on Apply. And Close this Firewall window.

6. Run the deploy.js file by running the command in the WSL terminal window:
   node deploy.js

Thanks a lot to All the people answering & also asking their doubts. ✌

[Renzo1]

I just checked the Gas Price and Gas Limit settings on my Ganache, they are same as yours. The problem still persist, an I'm also unable to execute the code in the subsequent examples. Is there an alternative to Ganache I can try out? This is really so me down.

Thanks again for the support.

[SWank74]

Check this:
https://ethereum.stackexchange.com/questions/83222/vm-exception-while-processing-transaction-invalid-opcode-error

Recompile your contract and deploy again. Let's see if it works.

[Renzo1]

Thank @SWank74 once again for all the support. I have managed to resolve the issues by retracing my steps.

Upon investigation, I discovered that the problem did not originate from Ganache, as I was able to record transactions on my local network successfully. Instead, the issue lied with my contract, which was not functioning as expected and kept throwing errors.

To address this, I decided to start afresh in my regular Windows environment, assuming that some of the complexities might have arisen from using the WSL (Windows Subsystem for Linux) virtual environment. In order to overcome the limitations of the Windows Command Prompt, I installed Hyper terminal, which allows me to run similar Unix commands as in the WSL terminal.

To summarize, after going through the tutorial steps again, I realized that my installation of solc was incorrect, resulting in my contracts not compiling properly. Additionally, I found that the latest versions of Ether.js (6.0.0 and above) were not compatible with the examples provided in the course. Consequently, I downgraded to "ethers": "5.6.2", which resolved the issue.

I appreciate the support, and I now feel relieved as I can continue with the rest of the course.

[ZamoRzgar]

Thank you very much, the second one worked for me since I downloaded it on windows.

[shivamani-yamana]

Thank you so much

[EightMilesZhangjx]

thanks very much! it works.

[Rwendo-snowden]

Thank you very much for this contribution option 2 worked for me

[takbeeralikhan]

Thank you so much it worked for me I tried for an hour in UI but rejected the gas limit again and again, CLI worked for me 🎉🧨🎊

[felipe-muner]

Just updating to help folks, I've done today with latest ethers and all good:

Install Ganache on WSL
yarn add ganache

Run Ganache
yarn run ganache

const ethers = require("ethers")
const fs = require("fs")

async function main() {
    const provider = new ethers.JsonRpcProvider("http://127.0.0.1:8545");
    const wallet = new ethers.Wallet(`you should change here with one of many available after running run ganache`, provider);
    console.log('wallet - - - -', wallet.privateKey);

    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");
    const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf-8");

    const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
    console.log("Deploying, please wait...")
    const contract = await contractFactory.deploy();
    console.log('contract - - -', contract);
}

main()
    .then(() => process.exit(0))
    .catch(error => {
        console.error(error);
        process.exit(1);
    })
