測試項(xiàng)目Laravel Shop，Git源代碼到本地調(diào)整，環(huán)境配置完成之后，運(yùn)行Laravel，報(bào)錯(cuò)信息如下：
The Mix manifest does not exist.
查看package.json文件，發(fā)現(xiàn)cross-env缺少了一些環(huán)境的支持
至Node.js官方下載Windows LTS版本，并進(jìn)行安裝

檢查安裝的版本信息：
$ node -v
v10.16.2
$ npm -v
6.9.0
然后就只需要安裝 Laravel Mix。在新的 Laravel 項(xiàng)目中，你可以在目錄結(jié)構(gòu)的根目錄中找到一個(gè) package.json文件，它包括了運(yùn)行基本的 Mix 所需的內(nèi)容。就如同 composer.json 文件，只不過它定義的是 Node 的依賴而不是 PHP。你可以使用以下的命令安裝它引用的依賴項(xiàng)：
npm install
如果你正在 Windows 系統(tǒng)上進(jìn)行開發(fā)，或者在 Windows 主機(jī)系統(tǒng)上運(yùn)行虛擬機(jī)，那你要在運(yùn)行 npm install命令時(shí)使用 --no-bin-links：
$ npm install --no-bin-links

運(yùn)行 Mix
Mix 是位于 Webpack 頂部的配置層，所以要運(yùn)行 Mix 任務(wù)，只需要執(zhí)行默認(rèn)的Laravel package.json 文件中包含的一個(gè) NPM 腳本：
$ 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

監(jiān)控資源文件修改
npm run watch 會在你的終端里持續(xù)運(yùn)行，監(jiān)控所有相關(guān)的資源文件以便進(jìn)行更改。
Webpack 會在檢測到文件更改時(shí)自動重新編譯資源：
$ npm run watch
在某些環(huán)境中，當(dāng)文件更改時(shí)，Webpack 不會更新。如果系統(tǒng)出現(xiàn)這種情況，請考慮使用watch-poll 命令在后臺運(yùn)行：
$ npm run watch-poll &
