Question

我想在我的laravel项目中执行“ npm run watch”，但是它不起作用。有错误消息

@观看/ Applications / MAMP / htdocs / test-tech / laravel5   npm运行开发---watch

@开发/ Applications / MAMP / htdocs / test-tech / laravel5   cross-env NODE_ENV =开发node_modules / webpack / bin / webpack.js --progress-隐藏模块--config = node_modules / laravel-mix / setup / webpack.config.js“ --watch”

我在Google上搜索并尝试了一些解决方案，但仍然无法正常工作。如何解决？

谢谢

问题是您缺少cross-env，可以运行 npm install -g cross-env将其全局安装，或npm install cross-env将其本地安装在当前项目中。

Npm run watch不适用于laravel：sh：cross-env：命令未找到
