node server.js 會工作，但 npm start 不會

Question

我在使用 npm 運行節點應用程序時遇到問題。 當我嘗試node server.js它會工作，但是當我嘗試npm start它給了我以下錯誤：

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 包括啟動腳本：

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

這是我的 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)

我最近更新到 10.13.0 版本的 Node，如果這可能是問題所在？ 我已經嘗試清理緩存。

這是日志：

Answer 1

我剛修好。 必須使用此鏈接中的答案完全卸載節點，然后從頭開始安裝節點和 npm。 我猜這與 PATH 變量有些沖突。 現在一切正常。 不管怎么說，多謝拉！

遇到了類似的問題。 如果您使用的是 Windows，請確保%userprofile%\\.npmrc包含script-shell=cmd 。 花了幾個小時試圖找出這個錯誤......
