JavaScript-节点js退出状态8,错误代码0在Mac上运行

根据this指南,我遇到了一个错误,但不确定是什么问题.

我设法到达步骤2的末尾没问题,我重新启动了服务器npm start.然后我对玉器文件a了一下,再次跑回起点,它mo吟着,而很少放入原木中.在此发布之前,我删除了整个文件夹并重新启动,但是现在npm服务器甚至都不会以express创建的基本文件开头.

当我运行时：npm install -g express和本地用户一样,我得到错误提示我以root用户身份运行.因此express是作为root用户安装的,但是npm install -g express-generator作为本地用户运行得很好.

因此,在安装了express和express生成器之后,我现在可以创建一个express项目(以本地用户身份登录,而不是以root用户,项目名称… noders身份登录)：

<code>express noders
</code>

现在npm install获取所有依赖项：

<code>npm install
</code>

因此,从理论上讲,我现在应该能够启动节点js服务器…

<code>npm start
</code>

但是结果是：

<code>Janines-MacBook-Pro:noders janinenitz$npm start

> noders@0.0.0 start /Users/janinenitz/node/noders
> node ./bin/www

看完其他几篇文章后,我停止了节点服务器npm stop,然后再次开始,希望端口号没有冲突,但我得到了相同的结果.

当我以root身份运行时,得到的结果完全相同.

有人有什么想法吗？与节点一起安装的每个站点是否都占用一个端口号,并且需要删除端口或其他内容？

当运行lsof -i时,这是结果(关闭Web浏览器之后)：

<code>COMMAND   PID       USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

</code>

没有任何迹象表明在端口3000上监听(这是我之前从上面的教程获得的默认页面),我重新启动了npm,仍然得到与上述相同的结果：

<code>events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: listen EADDRINUSE
    at errnoException (net.js:905:11)
    at Server._listen2 (net.js:1043:14)
    at listen (net.js:1065:10)
    at Server.listen (net.js:1139:5)
    at Function.app.listen (/Users/janinenitz/node/noders/node_modules/express/lib/application.js:556:24)
    at Object.<anonymous> (/Users/janinenitz/node/noders/bin/www:7:18)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
... etc etc
</code>

我还尝试告诉app.js监听随机端口号：app.listen(31001);但仍然没有喜悦：S

我使用npm install构建和安装的先前应用程序现在是否有可能与该应用程序发生冲突？是否有“卸载” nodeJs应用程序的官方方法？

干杯,
?

解决方法:

错误：侦听EADDRINUSE表示已占用端口.您是否在指定的端口上运行另一个节点应用程序或某个服务器？我的猜测是你是.

如果要终止占用端口的进程,并且正在运行linux / mac,请在终端运行：

<code>lsof -i tcp:{DESIGNATED_PORT} // Example
lsof -i tcp:8080 // Yours will need to be something like so
</code>

您将看到如下输出：

<code>COMMAND    PID            USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
node      2940 sethkrasnianski   12u  IPv4 0xdce46e6699332713      0t0  TCP *:vrpn (LISTEN)
</code>

…然后抓取那个PID#并杀死-9 {PID_NUMBER}

否则,您应该只编辑app.js文件(或任何命名为入口文件的文件),然后将快速服务器分配给新的晦涩端口.
