Question

最近我使用“ create-react-app”更新了我的react项目（反应16.9）
更新之前一切正常，但是突然出现以下ESLint错误：（在“输出”选项卡中）

 [Error - 16:42:12] 
Failed to load plugin 'react' declared in 'client\.eslintrc': Cannot find module 'eslint-plugin-react'
Require stack:
- C:\Or\Web\VisualizationTool\VisualizationTool\__placeholder__.js
Referenced from: C:\Or\Web\VisualizationTool\VisualizationTool\client\.eslintrc
Happened while validating C:\Or\Web\VisualizationTool\VisualizationTool\client\src\hoc\Layout\Layout.jsx
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-react' is installed globally as well.
3. If ESLint is installed locally, then 'eslint-plugin-react' isn't installed correctly.

我的.eslintrc文件：

{
    "env": {
        "browser": true,
        "commonjs": true,
        "es6": true,
        "node": true
    },
    "extends": [
        "react-app",
        "eslint:recommended",
        "plugin:react/recommended"
    ],

        }
    },
    "plugins": [
        "react"
    ],
    "rules": {
        "quotes": [
            "error",
            "single",
            {

            }
        ],

            }
        ],

        "jsx-a11y/anchor-is-valid": "off",
        "no-useless-escape": 0,
        "no-console": 0,
        "no-debugger": 0,
        "no-empty": 0,
        "linebreak-style": 0,
        "import/first": 0,
        "import/imports-first": 0,
        "no-shadow": 0,
        "disable-next-line": 0,
        "no-case-declarations": 0,
    }
}

我在全局和本地都安装了ESLint和eslint-plugin-react，在这里我还缺少什么？

Answer 1

尝试检查您的ESLint插件的工作目录，因为您有一个带有create-react-app更新的新项目。遇到相同的问题，我通过检查ESLint插件设置中的工作目录来修复了我的问题。

Answer 2

我在VS代码中遇到了同样的问题。在VS代码ESLint设置中添加以下设置：

{
  "eslint.workingDirectories": [
    "Dir1",
    "Dir2"
  ],
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact",
  ]
}

注意：Dir1和Dir2是两个目录，分别带有各自的.eslintrc文件。

Answer 3

我也遇到了类似的错误（我不确定原因是否相同，但这就是我发现问题的方式）。

因此请确保 Require Stack 的路径（在错误中）没有指向您的项目目录之外。

所以你有一个项目的根目录（你有 node_modules 文件夹等）。在终端 $ cd ..（转到保存您的项目的文件夹）中，执行以下操作：

$ ls -a

如果您看到名为 .eslintrc.js 的文件，请将其删除 ($ rm .eslintr.js)。然后只需重新加载您的项目，问题（至少在我的情况下）就会消失。

Answer 4

找到了。
1.在“扩展”部分中仅保留“ eslint：recommended”。删除所有其他内容。
2.删除了“插件”部分。
3.重新启动VSCode。
4.像魅力一样工作！

我更新的.eslintrc文件如下所示：

{
    "extends": "eslint:recommended",
    "env": {
        "browser": true,
        "commonjs": true,

        "es6": true
    },
    "parser": "babel-eslint",
    "parserOptions": {
        "ecmaVersion": 2018,
        "ecmaFeatures": {

        },
        "sourceType": "module"
    },
    "settings": {
        "react": {
            "pragma": "React",
            "version": "16.9"
        }
    },
    "rules": {
        "quotes": [
            "error",
            "single",
            {

            }
        ],

        "default-case": [
            "error",
