Question

我在使用npm运行节点应用程序时遇到问题。当我尝试node server.js时它将起作用，但是当我尝试npm start时会出现以下错误：

npm ERR! file bash
npm ERR! path bash
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn bash
npm ERR! sample-app@1.0.0 start: `node server.js`
npm ERR! spawn bash ENOENT
npm ERR!
npm ERR! Failed at the sample-app@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\Nick\AppData\Roaming\npm-cache\_logs\2018-11-01T11_57_12_947Z-debug.log

我的package.json包含启动脚本：

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node server.js"
  },

这是我的server.js文件：

const express = require('express')
const app = express()

app.use(express.static('public'))
app.set('view engine', 'ejs')

app.get('/', (req, res) => {
    res.render('index')
})

app.listen(3000)

如果这可能是问题，我最近将Node更新到10.13.0版本？我已经尝试清理缓存了。

这是日志：

Answer 1

我刚刚修复了它。必须使用this link中的答案完全卸载节点，然后从头开始安装node和npm。我想这与PATH变量有些冲突。现在一切正常。还是谢谢你！

遇到了类似的问题。如果您使用的是 Windows，请确保 %userprofile%\.npmrc 包含 script-shell=cmd。花了几个小时试图找出这个错误......

节点server.js可以工作，但是npm start不能
