【问题描述】：

当我运行 npm start 时，我看到了错误。

我试过了，但没用：https://techoverflow.net/2019/04/01/how-to-fix-npm-err-missing-script-start/

“私人”：真的， “脚本”： "dev": "npm 运行开发", "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch-poll": "npm run watch -- --watch-poll", "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config。 js", "prod": "npm 运行生产", “生产”：“跨环境 NODE_ENV=生产 node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js” , “开发依赖”： "axios": "^0.17.1", "babel-plugin-syntax-dynamic-import": "^6.18.0", "babel-plugin-transform-class-properties": "^6.24.1", "babel-preset-react": "^6.23.0", "bootstrap-sass": "^3.3.7", “跨环境”：“^5.2.0”， "jquery": "^3.2", "laravel-mix": "^1.0", "lodash": "^4.17.11", “反应”：“^16.5.1”， “反应域”：“^16.4.0” , “依赖”： "antd": "^3.12.4", "babel-plugin-import": "^1.8.0", "css-loader": "^2.1.0", "少": "^3.9.0", "less-loader": "^4.1.0", “时刻”：“^2.22.2”， "时刻-时区": "^0.5.21", “反应插件更新”：“^15.6.2”， "react-redux": "^5.0.7", “反应响应模式”：“^4.0.1”， "react-router-dom": "^4.3.1", "redux": "^4.0.0", "redux-thunk": "^2.3.0", “样式加载器”：“^0.23.1”

【问题讨论】：

作为解决方案，我已经运行 npm run dev，因为我需要 app.js 中的输出

【参考方案1】：

您的 package.json 中缺少名为“start”的脚本。查看脚本/开始行并在您的 package.json 中添加相同（但为您的文件修改）

"private": true,
"scripts": 
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "start": "node index.js"
,

    "redux-thunk": "^2.3.0",
    "style-loader": "^0.23.1"

【参考方案2】：

我尝试在将来从头开始删除并重新安装所有内容，即项目文件夹并运行最新的 react 安装，它对我有用。

再试一次：npm i -g create-react-app（没有版本号，在你打算工作的文件夹中）

提示：有时不要因为害怕而使调试过于复杂，有时尽管听写教程，但也不要尝试不同版本的软件。

祝你好运！

实际上，这个 YouTube 视频 @ 3:30 分钟为潜在的指导提供了一个类似的解决方案！ - bc 错误并不完全相同。
