Laravel Mix"sh:1:cross-env:not found error"

Question

我一直在尝试在我的项目上设置laravel mix并遵循laravel网站上的安装指南,但不断出现错误.

我的package.json文件是

当我运行任何npm run命令时,我得到的错误是

我在一个流浪的盒子里运行我的项目,我正在运行laravel 5.4.

Answer 1

您需要cross-env全局工作而不是在项目中使用它.

跑

$ sudo npm install --global cross-env

Answer 2

首先检查是否安装了cross-env模块.如果没有,请运行:

npm install cross-env

之后,您需要转到该node_modules文件夹.然后找到cross-env文件夹.走进去找cross-env.js.

就我而言 mode_modules/cross-env/dist/bin/cross-env.js

您需要更改路径,cross-env.js在scripts一节中的package.json文件.

{
  "private": true,
  "scripts": {
    "dev": "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_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",
    "hot": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development webpack-dev-server --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "production": "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"
  },

........

}

Answer 3

如果上述解决方案不起作用，请使用刷新 node_modules

rm -rf node_modules && npm install

这对我有用

Answer 4

跑:

npm install

然后再试一次.

Answer 5

快速的解决方案是运行：

npm clean-install

这可以解决 Laravel 混合错误。

Answer 6

有几种方法可以解决此错误.

• 删除node_modules文件夹然后npm install再次执行.如果它没有解决那么:

• 您可以dev dependency通过解雇来安装

npm install --save-dev cross-env

如果它没有解决那么:

• cross-env全局安装为npm install --g cross-env它将安装在\ Users\Roaming \npm模块中.然后我建议您关闭shell并再次打开它并触发命令.

如果它没有解决那么: - 在Package.json你可以使用如下:

node node_modules/dist/bin/cross-env cross-env ...
