Couldn't update node.js on wsl

[machinesr]

copying : node/20.12.2
   installed : v20.12.2 to /usr/local/bin/node
      active : v16.14.2 at /root/.nvm/versions/node/v16.14.2/bin/node

I couldn't use node v20.12.2 in wsl vs code, but I could use it at my normal vs code

If I tried to activate node 20.12.2, the yarn became error

root@:/hh-fcc/hardhat-simple-storage-fcc# yarn -v
ERROR: There are no scenarios; must have at least one.
root@:/hh-fcc/hardhat-simple-storage-fcc# yarn hardhat compile

The issue you are facing happens because you installed the wrong yarn. To resolve the issue:

1. sudo apt remove yarn
2. sudo apt remove cmdtest
3. curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
4. sudo apt update && sudo apt install yarn
5. yarn -v

NOTE: The 3rd step works for Ubuntu 16.04 or below.

What should be the version of the yarn for latest ubuntu??

[adityakhare86]

By default you get the latest version of yarn. Though, you can explicitly specify if you want some other version. You can do that by following the steps marked in the answer with a change step 4.

Change sudo apt update && sudo apt install yarn
to sudo apt update && sudo apt install yarn=<version>.
