Solved: How to change Solidity linter [solc] compiler version in Visual Studio Code?

Question

Hi may I know how to change my Solidity linter compiler version in Visual Studio Code(vscode)? OR Visual studio code how to specify solidity compiler version?

The only Solidity related extensions I have installed are solidity 0.0.38 by Juan Blanco, and Solidity Extended 3.0.2 by beaugunderson.

I have applied the User Settings in VS Code as the following but still get error:

{"files.autoSave": "afterDelay",
  "files.autoSaveDelay": 1000,
  "editor.minimap.enabled": false,
  "editor.tabSize": 2,
  "editor.detectIndentation": false,
  "editor.wordWrap": "on",
  "files.associations": {
    "*.sol": "solidity"
  },
  "workbench.iconTheme": "material-icon-theme",
  "material-icon-theme.showUpdateMessage": false,

  "solidity.compileUsingRemoteVersion" : "latest",
  "solidity.linter":"solium",
  "solidity.packageDefaultDependenciesContractsDirectory": "contracts",
  "solidity.packageDefaultDependenciesDirectory": "node_modules",
  "solidity.soliumRules": {
    "imports-on-top": 0,
    "variable-declarations": 0,
    "no-inline-assembly": 5,
    "indentation": ["error",2],
    "quotes": ["error","double"]
  },
  "solidity.validationDelay": 1000,

  if in Windows system:
  "terminal.integrated.shell.windows":"C:\\WINDOWS\\System32\\cmd.exe",
  "window.zoomLevel":1

Now I've also install Solidity globally in my Linux: $ sudo npm install -g solc Then I've got this from the terminal: /home/userXYZ/.npm-global/bin/solcjs -> /home/userXYZ/.npm-global/lib/node_modules/solc/solcjs + [email protected]

Then changed User Setting: "solidity.compileUsingRemoteVersion" : "latest"

Then re-started VS Code, still I am getting this error... Please help. Thank you

Answer 1

If you still have a problem with the version in VS Code, this worked for me:

Install specific solc version locally or globally: npm i -g solc or npm i solc.

Add this setting in local VSCode settings: .vscode/settings.json

{
    "solidity.compileUsingRemoteVersion": "v0.7.4+commit.3f05b770",
    "solidity.enableLocalNodeCompiler": false
}

In my case I am using solidity v0.7.4. Note also the other config: "solidity.enableLocalNodeCompiler": false

Answer 2

Assuming your using VS code and have the official solidity extension maintained by Juan Blanco (found here). The extension is official in the sense that it is the only extension recommended by ethereum.org.

The extension provides a very easy way of toggling compilers:

1. In any *.sol file, right click and press "change workspace compiler version (Remote)".

2. Choose your compiler.

Thats it.

Answer 3

[Solved] Thank you Juan Blanco for his advice. So the main issue is that the forked extension(Solidity Extended by beaugunderson) was highjacking this one(solidity by Juan Blanco) hence I had the old version of the compiler 0.4.17 but not the latest version 0.4.23.

Set it by opening your VS Code setting at /home/userXYZ/.config/Code/User/settings.json in Linux, then change the compiler version like below

"solidity.compileUsingLocalVersion": "null",

"solidity.compileUsingRemoteVersion" : "v0.8.0+commit.c7dfd78e",

Answer 4

Go to node_modules -> solc -> package.json -> version of your compiler can be found at the bottom.

Never edit the package.json file

To fix the problem

-Copy the version number at the bottom ex:-"version": "0.5.1"

-go to your contract and paste on pragma. ex:- pragma solidity ^0.5.1;

This should fix your issue.

Answer 5

I tried sooooooooo many things to fix this in Nov 2021 and this is finally what did it for me....btw, many thanks to Russo for his insight about Blanco's extension vs Beaugunderson's! While his quick fix didn't immediately fix, I was able to find the needle in the haystack, finally:

• Open VSCode
• On left side, open Extensions (Now here, check what Solidity extensions you installed! I happened to have had BOTH Blanco's and Beaugunderson's extension installed - You only need Blanco's! So make sure HIS is installed and if you have Beaugunderson's then uninstall it! Should only have Blanco's..) Done. This worked at least for me. Hope it works for you.

Answer 6

This is what helped me. In the file named .solhint.json, I replaced

{
  "extends": "solhint:recommended",
  "rules": {
    "compiler-version": ["error", "^0.8.0"],
    "func-visibility": ["warn", { "ignoreConstructors": true }]
  }
}

with this

{
  "extends": "solhint:recommended",
  "rules": {
    "compiler-version": "^0.6.0",
    "func-visibility": ["warn", { "ignoreConstructors": true }]
  }
}

Answer 7

In my case I had to npm install solc@specific-version-number

This resolved the error for me

Answer 8

I've noticed this question was answered, but just in case others are using Hardhat, you can edit the hardhat.config.js with an entry for the Solidity compilers you want. If a version isn't installed, hardhat will install it for you. Here's an example:

solidity: {
    compilers: [
     
      {
        version: "0.6.0",
      }, 
      {
        version: "0.8.10",
      },
    ],
  },
