'node' 不是内部或外部命令，也不是可运行的程序或批处理文件；仅在尝试启动应用程序时

Question

因此，如果我想 npm 安装一个包或检查节点或 npm 版本，它可以工作，但如果我尝试使用任何脚本启动应用程序，它就会显示这个。 [已编辑]

$ npm start

> nibblin@0.0.0 start C:\Users\trevc\Desktop\Projects\nibblin
> concurrently "npm run server" "npm run client"

'node' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! nibblin@0.0.0 start: `concurrently "npm run server" "npm run 
client"`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the nibblin@0.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional 
logging output above.

这是我的包裹

{
  "name": "nibblin",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "server": "node ./bin/www",
    "client": "npm start --prefix client",
    "start": "concurrently \"npm run server\" \"npm run client\""
  },
  "dependencies": {
    "cookie-parser": "~1.4.3",
    "debug": "~2.6.9",
    "express": "~4.16.0",
    "http-errors": "~1.6.2",
    "jade": "~1.11.0",
    "morgan": "~1.9.0",
    "concurrently": "^3.6.1"
  }
}

删除所有节点模块并尝试重新安装后，我遇到了这个问题

这只发生在我用 create-react-app 创建的客户端文件夹中

Answer 1

您运行的 npm 脚本是 node server.js 但在您的 package.json 中您将启动脚本定义为 node ./bin/www.

react_redux_express_starter 锅炉播放器中没有 bin 或 www 文件夹。所以我想要么你从另一个样板复制了一个package.json，要么弄乱了文件结构，要么运行命令在错误的目录中。
