Laravel 报错The Mix manifest does not exist,解决办法！

环境配置完成之后，运行Laravel，报错信息如下：

The Mix manifest does not exist.

查看package.json文件，发现cross-env缺少了一些环境的支持

到Node.js官方下载Windows LTS版本，并进行安装

}

}

检查安装的版本信息：

$ node -v

v10.16.2

$ npm -v

6.9.0

然后就只需要安装 Laravel Mix。在新的 Laravel 项目中，你可以在目录结构的根目录中找到一个 package.json文件，它包括了运行基本的 Mix 所需的内容。就如同 composer.json 文件，只不过它定义的是 Node 的依赖而不是 PHP。你可以使用以下的命令安装它引用的依赖项：

npm install

如果你正在 Windows 系统上进行开发，或者在 Windows 主机系统上运行虚拟机，那你要在运行 npm install命令时使用 –no-bin-links：

$ npm install –no-bin-links

运行 Mix

Mix 是位于 Webpack 顶部的配置层，所以要运行 Mix 任务，只需要执行默认的Laravel package.json 文件中包含的一个 NPM 脚本：

$ npm run dev

> @ dev D:\phpStudy\laravel-shop

> npm run development

> @ development D:\phpStudy\laravel-shop

> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js –progress –hide-modules –config=node_modules/laravel-mix/setup/webpack.config.js

监控资源文件修改

npm run watch 会在你的终端里持续运行，监控所有相关的资源文件以便进行更改。

Webpack 会在检测到文件更改时自动重新编译资源：

$ npm run watch

在某些环境中，当文件更改时，Webpack 不会更新。如果系统出现这种情况，请考虑使用watch-poll 命令在后台运行：

$ npm run watch-poll &
