Hey @babyface001, can I ask what the steps where that lead up to this error.

Once the error happens, what functionality do you lose, do the warnings and errors disappear or is it all of the extensions functions (navigation, renames, quickfixes etc)?

@kanej I open verbose log and it use js as cmd. and error.

[babyface001]

compile in terminal is ok

[babyface001]

[kanej]

And this happens when you open the project? Or when you run the build task?

[babyface001]

after this, import auto complete is missing.

[babyface001]

yes, open a sol file.

[babyface001]

maybe it try to compile it.

[kanej]

Okay. This is a bug we will dig into.

I suspect the issue is that the vscode process doesn't have permission on the solc compiler downloaded by hardhat, and that exception kills the language server (so autocomplete and other features stop working.)

[kanej]

Are there any special file permissions, or anything around your user that would block permission on: /Users/baby/Library/Caches/hardhat-nodejs/compilers/wasm/soljson-v0.8.17+commit.8df45f5f.js?

[babyface001]

I run chmod +x, but now work, it run js with /bin/sh, right?

it run native compiler with js compiler path.

[babyface001]

compile:solidity:solc:run or compile:solidity:solcjs:run should be detected.
