我在一个流浪箱中运行我的项目，我正在运行 laravel 5.4。

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

您需要cross-env在全球范围内工作，而不是将其放在项目中。

run

跑

$ sudo npm install --global cross-env

$ sudo npm install --global cross-env

回答by Andrew Bodnar

First check if cross-env module is installed. If not, run:

首先检查是否安装了跨环境模块。如果没有，请运行：

npm install cross-env

npm install cross-env

After that you need to go to the node_modulesfolder. Then find cross-envfolder. Go inside and find cross-env.js.

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

In my case it was node_modules/cross-env/dist/bin/cross-env.js

就我而言，它是 node_modules/cross-env/dist/bin/cross-env.js

You need to change path to cross-env.jsin scriptssection in your package.jsonfile.

您需要将路径更改为文件中的cross-env.jsinscripts部分package.json。

{
  "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"
  },

There are couple of ways to solve this error.

有几种方法可以解决此错误。

• Delete node_modules folder then do npm installagain. if it doesn't solve then:

• You can install as dev dependencyby firing

• 删除 node_modules 文件夹，然后再做npm install一次。如果它没有解决那么：

• 您可以dev dependency通过触发来安装

npm install --save-dev cross-env

npm install --save-dev cross-env

if it doesn't solve then:

如果它没有解决那么：

• Install cross-envglobally as npm install --g cross-env It will install it in \Users\Roaming\npm modules. Then I suggest you can close your shell and open it again & fire the command.

• cross-env全局安装为 npm install --g cross-env 它将安装在 \Users\Roaming\npm 模块中。然后我建议你可以关闭你的外壳并再次打开它并启动命令。

if it doesn't solve then: - in Package.json you can use like:

如果没有解决，则： - 在 Package.json 中，您可以使用：

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

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

If the solutions above didn't work, refresh node_modules using

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

this worked for me

这对我有用

回答by kangular

Sometimes deleting the /node_modulesand running

有时删除/node_modules并运行

npm install 

will solve issues like this one.

将解决这样的问题。

回答by shamaseen

If you are just desperate of fixing this error like my case, just remove cross-envfrom you package.jsonand run laravel mix without it ..

如果你只是像我的情况一样急于解决这个错误，只需cross-env从你package.json身上删除并运行 laravel mix 而不用它..

回答by flap152

You do need to check if cross-env module is installed. If not, run:

您确实需要检查是否安装了跨环境模块。如果没有，请运行：

npm install cross-env

But you need it to be recognized as a "command". Patching the path as proposed by the accepted answer (or is it?) led me further, but still gave me an error.

但是您需要将其识别为“命令”。按照接受的答案（或者是？）修补路径使我更进一步，但仍然给了我一个错误。

The solution for me was to reload vagrant "vagrant reload --provision", and reset my ssh / putty session.

我的解决方案是重新加载 vagrant "vagrant reload --provision"，并重置我的 ssh/putty 会话。
