'node'不被识别为内部或外部命令、可操作程序或批处理文件;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，但如果我尝试用任何脚本启动应用程序，它会显示这一点。[编辑]

$ npm start
> nibblin@0.0.0 start C:UserstrevcDesktopProjectsnibblin
> 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"
}
}

在删除所有节点模块并尝试重新安装后，我面临着这个

$ npm i

这只发生在我的客户端文件夹创建反应应用

Answer 1

您正在运行的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。

在react_redux_express_starter锅炉播放器中，没有bin或www文件夹。所以我想，要么是从另一个样板文件中复制了一个package.json，要么是文件结构搞砸了，要么是在错误的目录中运行了命令。
