npm start looking for /bin/www in the wrong directory, how to update
提问by subpath42
So I'm following This Tutorial hereto get a personal/learning node.js project off the ground that I would like to work on and store in GitHub and eventually put onto a live server or cloud hosting. It's using node.js, express, monk, mongoDB for a website setup. However I have a persistent error that I haven't found an answer to when I run 'npm start'.
因此，我正在关注这里的本教程，以开始一个个人/学习 node.js 项目，我希望在 GitHub 上工作并存储该项目，并最终放到实时服务器或云托管上。它使用 node.js、express、mongo、mongoDB 进行网站设置。但是，当我运行“npm start”时，我有一个持续性错误，我没有找到答案。
Here is my command window output when I try to run 'npm start' inside my node express project.
这是我尝试在 node express 项目中运行“npm start”时的命令窗口输出。
I know that: Error: Cannot find module 'C:\Users\username\Desktop\bin\www' is not where my bin\www is located (it's inside the nodetest1 project).
我知道：错误：找不到模块 'C:\Users\username\Desktop\bin\www' 不是我的 bin\www 所在的位置（它在 nodetest1 项目中）。
C:\Users\username\Documents\GitHub\TEDResources\node.js\nodetest1 <-- correct path
C:\Users\username\Documents\GitHub\TEDResources\node.js\nodetest1 <-- 正确路径
So, why is npm looking at that incorrect spot and how do I update it to correctly look at my project folder? I've searched my system and can't find module.js anywhere. (using windows 7 x64) I've also tried nuking node.js and express and started from scratch without luck.
那么，为什么 npm 会查看那个不正确的位置，我该如何更新它以正确查看我的项目文件夹？我已经搜索了我的系统，但在任何地方都找不到 module.js。（使用 Windows 7 x64）我也试过 nuking node.js 和 express 并从头开始没有运气。

Had a windows registry entry for "autorun" - "problem directory" setup for a default start directory that was overriding commands. Removed it from registry and fixed the issue. Thank you to laggingreflex for helping me debug this.
有一个用于“自动运行”的 Windows 注册表项 - 为覆盖命令的默认启动目录设置的“问题目录”。从注册表中删除它并修复了问题。感谢 laggingreflex 帮助我调试这个。

I had this same error when I was creating my First Node Project using express. But when i tried running it using
当我使用 express 创建我的第一个节点项目时，我遇到了同样的错误。但是当我尝试使用它运行它时
node ./bin/www // it will work
instead of
代替

The server started at port 3000. you can check your app on localhost:3000 .
May be it can help some One else :)
服务器从端口 3000 启动。您可以在 localhost:3000 上检查您的应用程序。
也许它可以帮助其他人:)

Fwiw, I had the same error and it turned out to be that something was already running on port 3000. I mention this because the debug log mentioned nothing about this, just a similar error to yours. So maybe this will help somebody who comes across this post and happens to have the problem I did.
Fwiw，我遇到了同样的错误，结果是某些东西已经在端口 3000 上运行了。我提到这个是因为调试日志没有提到这个，只是一个与你类似的错误。所以也许这会帮助那些遇到这篇文章并且碰巧遇到我遇到的问题的人。

I had the same problem following this tutorial, only after killing server for the first time as per instructions. I tried a bunch of things, including those listed above and on several other threads. However simply removing or commenting out the following in app.js did the trick :
我在遵循本教程后遇到了同样的问题，只是在按照说明第一次杀死服务器之后。我尝试了很多东西，包括上面列出的和其他几个线程上的那些。然而，简单地删除或注释掉 app.js 中的以下内容就可以了：
//var mongo = require('mongodb')

This happened to me today, same error looking to the same tutorial, but with this setup:
今天发生在我身上，同样的错误寻找同一个教程，但使用以下设置：
- Ubuntu 14.04
- npm v5.11.1
- node v3.9.2
- Ubuntu 14.04
- npm v5.11.1
- 节点 v3.9.2
First intent was searching on the web and found this page, and can't solve the problem with what was said, but found a clue to follow.
第一个意图是在网络上搜索并找到了这个页面，并且无法解决所说的问题，但找到了一个可以遵循的线索。
Second intent was to list apps using the same port (3000) with this:
第二个意图是列出使用相同端口 (3000) 的应用程序：
sudo netstat -ep | grep 3000
But nothing.
但没什么。
Third intent was to change the port number used un "nodetest1/bin/www" file from 3000to 3001, and that did the trick.
第三个意图是将“ nodetest1/bin/www”文件中使用的端口号从3000更改为3001，这就是诀窍。
var port = normalizePort(process.env.PORT || '3001');
From there, I now can browse http://localhost:3001and keep following the tutorial.
从那里，我现在可以浏览http://localhost:3001并继续遵循教程。
Edit:I've found that I've incorrectly used netstat, and this showed whats program is using the port 3000:
编辑：我发现我错误地使用了 netstat，这表明什么程序正在使用端口 3000：
sudo netstat -epa | grep 3000
ntop is using it:
ntop 正在使用它：
tcp 0 0 *:3000 *:* ESCUCHAR root 15508 2289/ntop
So in my case changing the nodetest1 port on www file was the only viable solution.
因此，在我的情况下，更改 www 文件上的 nodetest1 端口是唯一可行的解决方案。
Hope this help others.
希望这对其他人有帮助。

I had the same error, so i run:
我有同样的错误，所以我运行：
npm install
and then:
进而：
npm start
and that works for me
这对我有用

In the tutorial's app.js file, be sure to name the index object as follows:
在教程的 app.js 文件中，请务必按如下方式命名索引对象：
var index = require('./routes/index');
This should correct the error.
这应该纠正错误。
Despite what the tutorial author says, the error will throw if that line reads:
不管教程作者怎么说，如果该行显示为：
var index = require('./routes/routes');
