Question

伙计们，请你帮我解决这个问题，我在为我的Laravel Mix运行npm run dev时遇到了麻烦。我按照下面的链接但仍然存在错误。我的操作系统有问题吗？我尝试删除 node_modules ，运行 npm install --global cross-env 。并再次运行NPM安装。

Laravel 5.4 'cross-env' is not recognized as an internal or external command

以下是我的版本：

Laravel mix版本：^ 2.0
节点版本（节点-v）：8.9.0
NPM版本（npm -v）：5.6.0
操作系统：Windows7
XAMPP

> @ development C:\xampp\htdocs\codetinerant
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

'cross-env' is not recognized as an internal or external command,
operable program or batch file.

Answer 1

首先，运行：

wcslen

然后运行命令

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force

，然后您也可以

npm install cross-env

npm install

您是否尝试按照dwoodward上Github issue建议的cross-env的建议路径指定package.json的路径？这包含在"dev": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch-poll": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "hot": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js", "production": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"文件中：

cross-env

这可能在更新版本的Laravel中有所改变，但要点是您应该将node_modules/cross-env/dist/bin/cross-env.js更改为even。

Answer 3

尝试将npm bin目录添加到系统路径例如C:\Users\DELL\AppData\Local\Yarn\bin

Answer 4

我有同样的问题。我通过卸载节点，然后运行以下命令来解决该问题：

npm install -d

'cross-env'未被识别为内部或外部命令，
