VistasThe eslint extension is configured as a formatter but cannot format JavaScript files:
I'm having an intermittent issue with ESLint in VS Code. When saving a file, instead of formatting it, this message appears in the status bar:
Apparently no one has ever reported this message to Google.
When I say it's intermittent, it was working fine, then the computer (MBP) crashed and on reboot this is the situation. It's happened before, but I don't remember what I did to fix it.
The app is a fairly complex Vue-based app based on a preconfigured template. In package.json:
"@vue/cli-plugin-eslint": "^4.5.13", "babel-eslint": "^10.1.0", "eslint": "^7.31.0", "eslint-plugin-import": "^2.23.4", "eslint-plugin-vue": "^7.14.0",In the VS Code workspace file:
"editor.codeLens": true, "eslint.format.enable": true, "editor.codeActionsOnSave": { "source.fixAll.eslint": true, }, "[javascript]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" }, "[vue]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" }, "eslint.validate": [ "javascript" ], "debug.javascript.usePreview": true, "debug.javascript.usePreviewAutoAttach": true, "[jsonc]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" },I'm really not sure how to go about understanding why vscode-eslint reports that it can't format JavaScript files.
EDIT
This TypeScript related issue gives some clues. It seems that this error can occur when the ESLint server is restarting or the extension host is under a lot of pressure.
In my project now most of the files are formatted fine, although one fails constantly. That file is called eslint.js and is part of a build process, running eslint; I don't fully understand the configuration. I suspect that saving this file somehow causes eslint to run/reload, and while that's happening eslint-vscode also tries to run it and fails.

I was actually experiencing the same problem and I only needed to remove the .eslintignore file, which only contained this line:
.eslintrc.js
You could simply comment that line too.
Hope that helps :)

For me, it seemed as if StandardJS was trying to lint everything in my node_modules folder. The error went away and linting started working again after adding a standard.ignore property to my package.json, followed by reloading VSCode:
{
"name": "foo",
"devDependencies": {
"standard": "^16.0.4"
},
"dependencies": {
// stuff...
},
"standard": {
"ignore": [
"**/node_modules/**"
]
}
}
No idea why this behavior didn't happen automatically...
UPDATE:
I previously had installed eslint alongside standard, which may have been the root cause. My original install command was npm install standard eslint, which installed the latest version of eslint, v8.x.x. However, standard (at the time of writing) depends on eslint v7.x.x, causing a conflict.
The fix:
~$ npm uninstall eslint # remove eslint from package.json
~$ rm -rf node_modules # remove node_modules
~$ npm install # get fresh installation
