Solidity Compiler Settings Missing from preferences

[DorianDaSilva]

Hi,

Solidity compiler v0.8.14 is installed correctly on Ubuntu

Version: 0.8.14+commit.80d49f37.Linux.g++

but SimpleStorage.sol reversed and now returns an error stating that it is in v0.4.

ethers-simple-storage/SimpleStorage.sol:2:1: SyntaxError: Source file requires different compiler version (current compiler is 0.4.17+commit.bdeb9e52.Emscripten.clang - note that nightly builds are considered to be strictly less than the released version
pragma solidity ^0.8.8;

All Solidity Compiler settings have disappeared from preferences and editing in settings.json returns

solc error: TypeError: solc.compileStandardWrapper is not a function

And when I try to run node deploy.js I get this error:

TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

Mind you that compiler was working fine until we introduced Ganache UI to the mix. Doe anyone know where I went wrong, plz? Or should I just restart the lesson from scratch? Thank you!

Hi Dorian! Have you try looking at the file "hardhat.config.js"?

above must say: module.exports = { solidity: "0.8.8",

Please let me know if that works fine and solve the issue.
Thanks

@javierdash Hi Javier, thank you for the tip. Unfortunately I don't have hardhat.config file for some reason. Not sure what's going on. Should I install hardhat from the command line instead of relying on the solidity+hardhat extension?

[javierdash]

From what I saw in the tutorial and it worked fine for me, was to do the following:

1. yarn init
2. yarn add --dev hardhat
3. yarn hardhat

Automatically the following files should appear: "hardhat.config.js" "yarn.lock" and "node_modules".
If you don't see them in VSC, they have probably been created in another folder (and not in the one you are currently working in)

If that's what happened, what you can do is look directly from your computer for the file "hardhat.config.js "There you will find where it was saved, and if it's not in the same folder you are working in, you can delete it, and then reinstall hardhat from the terminal (make sure you are in the correct path) and it should work :)

@javierdash I have removed and reinstalled solc for specific version

yarn remove solc

yarn add solc@0.8.13

error has disappeared but still no hardhat.config

I do have the "yarn.lock" and "Node_modules"

What i find strange is that I did run the install commands for hardhat succesfully but hardhat.config never popped up.

I don't know why
