ESLint fails to load plugins when using ESLint 6.x

[samrith-s]

I have the following packages installed as dev deps:

{
    "babel-eslint": "^10.0.2",
    "eslint": "^6.0.1",
    "eslint-config-prettier": "^5.1.0",
    "eslint-plugin-import": "^2.18.0",
    "eslint-plugin-prettier": "^3.1.0",
}

And this is my .eslintrc file:

{
    "parser": "babel-eslint",
    "plugins": ["import", "prettier"],
    "extends": [
        "eslint:recommended",
        "plugin:import/errors",
        "plugin:import/warnings",
        "prettier"
    ],
    "settings": {
        "import/resolver": {
            "node": {
                "extensions": [".js"]
            }
        }
    },
    "env": {
        "es6": true,
        "browser": false,
        "node": true,
        "jquery": false,
        "jest": true
    },
    "rules": {
        "quotes": 0,
        "no-console": 1,
        "no-debugger": 1,
        "no-var": 1,
        "no-trailing-spaces": 0,
        "eol-last": 0,
        "no-underscore-dangle": 0,
        "no-alert": 0,
        "no-lone-blocks": 0,
        "import/extensions": 1,
        "import/no-named-as-default": 0,
        "prettier/prettier": [
            "error",
            {
                "singleQuote": true
            }
        ]
    },
    "globals": {
        "Atomics": false,
        "SharedArrayBuffer": false
    }
}

I have Format on Save on. When I run eslint --fix, it works properly. But when I hit save, I get the following error. It doesn't work for any plugin, even though I have all of them installed.

I'm getting the same error. I'm using TypeScript + Yarn workspaces + Lerna and have all the plugins installed locally and globally.

Failed to load plugin prettier: Cannot find module 'eslint-plugin-prettier'
Happened while validating foo.tsx This can happen for a couple of reasons:
1. The plugin name is spelled incorrectly in an ESLint configuration file (e.g. .eslintrc).
2. If ESLint is installed globally, then make sure 'eslint-plugin-prettier' is installed globally as well.
3. If ESLint is installed locally, then 'eslint-plugin-prettier' isn't installed correctly.

Restarting Visual Studio Code seemed to have fixed it temporarily for me but the issue keeps coming back.

[samrith-s]

I still continue to have this problem, even after restarting VS Code. I've tried everything:

• Deleting node_modules and yarn.lock and running yarn install again.
• Removing the packages and adding them again.
• Removing ESLint and adding it again.

And weirdly, it's just a problem with this project. In another project, I get this error:

Cannot find module './utils/ast-utils'

@samrith-s since this seems to be setup specific can you share a GitHub repository I can clone that demos this.

[samrith-s]

I unfortunately cannot share the repository, it's a private one on GitHub. I'll setup a repository which tries to replicate this.

Also, could you just tell me what does plugin 'import' specified in CLIOptions means?? I do not have ESLint globally, and I get this error even when I remove the plugins attribute from my RC file.

@dbaeumer Here is a reproducible repository. Do let me know if you get the error, because I am getting it in this repository as well.

Also most likely related to this: prettier/prettier-vscode#672

[dbaeumer]

@samrith-s actually it works for me

[samrith-s]

@dbaeumer I think this happened with Prettier-ESLint integration on. I'm closing this issue as it is related to the issue with prettier-vscode and not with vscode-eslint. I started getting these errors after upgrading to Node 12.

I have this same problem and i don't use prettier-vscode.

@sevenmay What version of Node are you on?

@sevenmay What version of Node are you on?

v8.11.2

[saostad]

same problem here.

[dbaeumer]

Do any of you use eslint.runtime setting to point to a node version. Otherwise VS Code eslint uses the one shipped with VS Code itself so it don't matter which node version you have installed.
