Laravel 5.4"cross-env"未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:\projects\ptcs
> 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，但这没有帮助.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

您需要使cross-env全局运行，而不是在项目中使用它.

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部分中删除"cross-env": "^5.0.1",.实际上，您可以跳过此步骤，并保持package.json不变.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

看到它正常工作

PS在Windows 10上使用Laravel-5.4测试

P.P.S Windows 10不会出现此问题，因此更新是另一种解决方案.

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