Laravel 5.4 ‘cross-env’ 不被识别为内部或外部命令 [英] Laravel 5.4 ‘cross-env’ Is Not Recognized as an Internal or External Command

问题描述

我正在尝试为 Laravel Mix 运行 npm run dev，但出现此错误:

I'm trying to run npm run dev for Laravel Mix and I get this error:

> @ dev D:projectsptcs
> cross-env NODE_ENV=development webpack --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.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! @ dev: `cross-env NODE_ENV=development webpack --progress --hide-
modules --config=node_modules/laravel-mix/setup/webpack.config.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the @ dev script.

我将 node.js 更新为 6.11.0，将 npm 更新为 5.2.0，但没有帮助.我在 Windows 7 上运行 Homestead.

I updated node.js to 6.11.0 and npm to 5.2.0, but it didn't help. I'm running Homestead on Windows 7.

推荐答案

你需要让 cross-env 在全局范围内工作，而不是在项目中使用.

You need to make cross-env working globally instead of having it in the project.

1) 删除 node_modules 文件夹

1) remove node_modules folder

2) 运行

npm install --global cross-env

npm install --global cross-env

3) 从 package.json 文件 devDependencies 部分删除 "cross-env": "^5.0.1", .实际上，您可以跳过此步骤并保持 package.json 完好无损.如果您愿意.

3) remove "cross-env": "^5.0.1", from package.json file devDependencies section. Actually, you can skip this step and keep package.json intact. If you prefer.

4) 运行

npm install --no-bin-links

npm install --no-bin-links

5) 运行

npm run dev

看看它是否有效

P.S 在 Windows 10 上使用 Laravel-5.4 进行测试

P.P.S Windows 10 with Laravel-5.6 没有这个问题，因此更新是一个替代解决方案.

P.P.S Windows 10 with Laravel-5.6 does not have this problem, thus updating is an alternative solution.
