我正在一个无聊的盒子中运行我的项目，而我正在运行laravel 5.4。

您需要使cross-env全局运行，而不是将其包含在项目中。

运行

$ sudo npm install --global cross-env

相关讨论

首先检查是否安装了交叉环境模块。如果没有，请运行：

npm install cross-env

之后，您需要转到node_modules文件夹。
然后找到cross-env文件夹。进入并找到cross-env.js。

在我的情况下是node_modules/cross-env/dist/bin/cross-env.js

您需要在package.json文件的scripts部分中将路径更改为cross-env.js。

有两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。
    如果无法解决，则：

  • 您可以通过触发

    作为dev dependency进行安装

npm install --save-dev cross-env

如果无法解决，则：

  • 全局安装cross-env作为npm install --g cross-env
    它将安装在\\\\ Users \\
    绿洲\\
    pm模块。然后，我建议您可以关闭外壳并再次打开它

    您确实需要检查是否安装了交叉环境模块。如果没有，请运行：

    1
    npm install cross-env

    但是您需要将其识别为"命令"。按照接受的答案提出的路径打补丁(或者是？)使我走得更远，但仍然给我一个错误。

    对我来说，解决方案是重新加载流浪者" vagrant reload --provision"，并重置我的ssh / putty会话。
