iisnode 不使用 babel答案

【问题标题】：iisnode not working with babeliisnode 不使用 babel
【发布时间】：2016-06-18 14:05:19
【问题描述】：

我有这个小服务器，它在 iisnode 上运行良好：

index.js

var express = require('express')

var app = express()
var port = process.env.PORT

app.get('/test/foo', function(req, res) {
  res.send('HALLO WORLD')
})

app.listen(port)

但是，如果我想使用 Babel 并像这样重写我的应用程序：

index.js

require('babel-register')
require('babel-polyfill')
require('./server')

server.js

import express from 'express'

const app = express()
const port = process.env.PORT

app.get('/test/foo', (req, res) => {
  res.send('HALLO WORLD')
})

app.listen(port)

现在，如果我导航到 localhost/test/foo，我会收到以下错误消息：

Application has thrown an uncaught exception and is terminated:
Error: EEXIST: file already exists, mkdir 'C:\Windows\system32\config\systemprofile'
    at Error (native)
    at Object.fs.mkdirSync (fs.js:916:18)
    at sync (C:\Projects\winAuthTest\node_modules\mkdirp\index.js:71:13)
    at save (C:\Projects\winAuthTest\node_modules\babel-register\lib\cache.js:56:44)
    at _combinedTickCallback (internal/process/next_tick.js:67:7)
    at process._tickCallback (internal/process/next_tick.js:98:9)
    at Function.Module.runMain (module.js:577:11)
    at startup (node.js:159:18)
    at node.js:444:3

这是来自etw.bat的日志：

如果我从应用程序文件夹中的命令行运行node index.js，以下代码可以正常工作。

为了让我想要的用 Babel 编写的应用程序在 iisnode 上运行，我需要修改什么？

【问题讨论】：

如果您在开发时发现任何不需要编译步骤的好解决方法，请告诉我。我将求助于直接在节点上运行 Web 服务器 :(
这个 repo github.com/lancetw/react-isomorphic-bundle 似乎正在使用 iisnode 和 babel-core/register。没有足够的时间来研究它，但是一旦我有空闲时间，我会检查一下。
看起来他们在做同样的事情。他们使用 nodemon 在 dev 模式下运行 Node.js，而 web.config 用于生产使用已编译的文件（在 ./lib 中）
检查问题跟踪器，有人发布了更好的解决方法。看来是 babel-register 的缓存有问题

标签： javascript babeljs iisnode

【解决方案1】：

这似乎是 iisnode 和 babel-register 中的错误。如果你手动编译它就可以了。

我同时提交了一个错误：https://github.com/tjanczuk/iisnode/issues/518

编辑：由 matterker 在问题跟踪器上发布的更好的解决方法：

对于开发，您可以使用 web.config 中的应用配置设置禁用缓存：

<configuration>
  <appSettings>
    <add key="BABEL_DISABLE_CACHE" value="true" />
  </appSettings>
  [...]
</configuration>

此外，如果在生产环境中使用 babel/register，您还可以更改缓存位置： https://babeljs.io/docs/usage/require/#environment-variables

【讨论】：

【解决方案2】：

就像@user120242 指出的那样，这是 Babel 缓存的问题。我以这种方式修改了我的web.config 文件：

<configuration>
  <appSettings>
    <add key="BABEL_CACHE_PATH" value="C:\Babel\cache.json" />
  </appSettings>
  <system.webServer>
    <iisnode promoteServerVars="LOGON_USER" />
    <handlers>
      <add name="iisnode" path="index.js" verb="*" modules="iisnode" />
    </handlers>
    <rewrite>
      <rules>
        <rule name="test">
          <match url="/*" />
          <action type="Rewrite" url="index.js" />
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>

现在它工作得很好。

【讨论】：

还需要什么其他配置？我目前正在尝试执行此操作，但无法让服务器停止抱怨您的原始问题。
@Austin 对不起，伙计，已经两年了，这是一个玩具项目。想不起来了?
