根据 .eslintrc 文件中的规则，eslint 不会在 VSCode 中给出错误

Question

I have installed eslint globally using npm and I have added my own .eslintrc file which contains following code:

{
    "env": {
        "browser": true,
        "commonjs": true,
        "es6": true,
        "node": true
    },
    "extends": [
        "eslint:recommended",
        "plugin:react/recommended"
    ],
    "parserOptions": {
        "ecmaFeatures": {
            "experimentalObjectRestSpread": true,
            "jsx": true
        },
        "sourceType": "module"
    },
    "plugins": [
        "react"
    ],
    "rules": {
        "indent": [
            "error",
            "tab"
        ],
        "linebreak-style": [
            "error",
            "unix"
        ],
        "quotes": [
            "error",
            "single"
        ],
        "semi": [
            "error",
            "always"
        ]
    }
}

I have added following dev dependencies:

"eslint": "3.19.0",
    "eslint-config-standard": "10.2.1",
    "eslint-plugin-import": "2.7.0",
    "eslint-plugin-markdown": "1.0.0-beta.6",
    "eslint-plugin-node": "5.1.1",
    "eslint-plugin-promise": "3.5.0",
    "eslint-plugin-standard": "3.0.1"

and also installed eslint-plugin-react in my react native project. Still no indentation, semi colon, double quotes errors are shown, although parsing errors are shown. PS eslint plugin is enabled in VScode.

Exact same thing happened to me. And I found out the cause of this issue by looking at the Eslint log:

1. Open Command Palette by Ctrl + Shift + P
2. Select Eslint: Show Output Channel

In my case, the output channel displayed this: Failed to load config "airbnb-base" to extend from. Referenced from: ...eslintrc.js Failed to load config "airbnb-base" to extend from. Referenced from: ...eslintrc.js

I just forgot to do npm install after adding the dev dependencies!
