无法运行使用带有 npm 或 yarn 的 webpack 编写脚本 - "Couldn't find the binary"

Question

描述

我正在尝试使用 webpack 构建我的第一个 React 网站。使用 gulp 它构建良好。但是，当我尝试使用 webpack 在管理员下构建时，当我运行我的脚本 'build' 使用命令 'yarn build' 时，我收到以下错误：

error An unexpected error occurred: "Couldn't find the binary C:\WINDOWS\system32\cmd.exe;".

配置

我的节点版本是v9.8.0

我的纱线版本是1.5.1

我的package.json:

 {
  "name": "mywebsite",
  "version": "1.0.0",
  "description": "My personal website.",
  "main": "./src/App.jsx",
  "scripts": {
    "build": "webpack-dev-server --config ./webpack.config.js --mode development"
  },
  "author": "Akli Aissat",
  "license": "ISC",
  "dependencies": {
    "react": "^16.2.0",
    "react-dom": "^16.2.0",
    "react-router-dom": "^4.2.2"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.4",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "^6.24.1",
    "webpack": "^4.1.1",
    "webpack-cli": "^2.0.12",
    "webpack-dev-server": "^3.1.1"
  }
}

我的.babelrc:

{"presets": ["env", "react"]}

我的webpack.config.js:

const path = require("path");

module.exports = {
  entry: "./src/App",
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bundle.js"
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      }
    ]
  },
  devServer: {
    contentBase: path.join(__dirname, 'dist')
  }
};

我还将 Yarn 添加到我的环境变量 Path 中。

错误日志

我的 yarn-error.log 并没有给我任何关于错误的额外信息：

Trace: 
  Error: Couldn't find the binary C:\WINDOWS\system32\cmd.exe;
      at ProcessSpawnError.MessageError (C:\Program Files (x86)\Yarn\lib\cli.js:186:110)
      at new ProcessSpawnError (C:\Program Files (x86)\Yarn\lib\cli.js:201:118)
      at ChildProcess.<anonymous> (C:\Program Files (x86)\Yarn\lib\cli.js:30237:18)

      at onErrorNT (internal/child_process.js:379:16)
      at process._tickCallback (internal/process/next_tick.js:114:19)

非常感谢任何帮助。谢谢。

Answer 1

如我所料，问题出在我的 Windows 配置上，而不是我的项目。我怀疑系统环境变量是特定问题。我通过恢复 Windows.
