Laravel Mix“sh：1：cross-env：not found error”

问题描述 投票：26回答：5

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，但不断收到错误。

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。

laravel npm laravel-mix

你需要让cross-env在全球范围内工作，而不是在项目中使用它。

跑

$ sudo npm install --global cross-env

首先检查是否安装了cross-env模块。如果没有，请运行：

npm install cross-env

之后你需要去node_modules文件夹。然后找到cross-env文件夹。进去找cross-env.js。

在我的情况下，它是mode_modules/cross-env/dist/bin/cross-env.js

您需要在cross-env.js文件中的scripts部分中更改package.json的路径。

{
  "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"
  },

........

}

有几种方法可以解决此错误。

  • 删除node_modules文件夹，然后再次执行npm install。如果它没有解决那么：
  • 你可以通过射击安装为dev dependency

npm install --save-dev cross-env

如果它没有解决那么：

  • 全局安装cross-env作为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 ...

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

您需要检查是否已安装cross-env模块。如果没有，请运行：

npm install cross-env

但是你需要它被认为是一个“命令”。根据接受的答案提出修补路径（或者是它？）使我更进一步，但仍然给了我一个错误。

我的解决方案是重新加载流浪汉“vagrant reload --provision”，并重置我的ssh / putty会话。
