为 laravel 应用程序运行 npm

我正在尝试运行 npm run watch 以实现我在资产文件中执行的更改，但它不起作用。我正在创建一个 laravel 工具。

我已经安装了 npm，没有任何错误，但是当我运行 npm run watch 时，出现了以下错误。谢谢你的帮助。

            > npm run development -- --watch


        > @ development C:\Users\\Documents\tool
        > 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' is not recognized as an internal or external command,
        operable program or batch file.

你缺少corss-env节点模块

尝试关注

  1. node_modules从项目中删除文件夹
  2. 运行此命令npm install --global cross-env。
  3. "cross-env": "^5.0.1"从package.json文件 devDependencies 部分删除。
  4. 跑步npm install --no-bin-links
  5. 现在run npm run dev
