我安装了一个新的 Laravel 8 应用程序，然后我跑了……

npm install

后来我跑...

npm run dev

我收到以下错误。

'mix' 不被识别为内部或外部命令

Answer 1

您可能需要安装最新版本的 Laravel Mix。

npm install laravel-mix@latest --save-dev

Answer 2

当您的缓存保存以前的文件时，就会发生这种情况。清除缓存并再次安装npm

npm cache clean --force 然后： npm install npm fix audit 然后： npm run development
