【问题描述】：

Windows MEVN 堆栈项目我有npm start 终端输出：

$ npm start

> nodejs-starter@1.0.0 start C:\final-dip\diplom-master
> SECRET=diplom nodemon index.js

"SECRET" is not internal or external
command, executable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! nodejs-starter@1.0.0 start: `SECRET=diplom nodemon index.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the nodejs-starter@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Admin\AppData\Roaming\npm-cache\_logs\2018-05-04T10_33_19_073Z-debug.log

package.json 中的代码：

  "main": "index.js",
  "scripts": {

【解决方案1】：

您的start 脚本缺少cross-env。将您的 package.json 更改为：

{
  "scripts": {
    "start": "cross-env SECRET=diplom nodemon index.js"
  }
}

它已在debug 脚本中使用。

注意它也不属于依赖项，因此必须通过npm i cross-env --save 添加。

【讨论】：

"cross-env" 不是内部或外部命令、可执行程序或批处理文件。 npm 错误！代码 ELIFECYCLE npm 错误！ errno 1 npm 错误！ nodejs-starter@1.0.0 开始：cross-env SECRET=diplom nodemon index.js npm ERR！退出状态 1 npm ERR！ npm 错误！在 nodejs-starter@1.0.0 启动脚本中失败。 npm 错误！这可能不是 npm 的问题。上面可能还有额外的日志输出。
需要添加到package.json。 npm i cross-env --save
