尝试运行均值堆栈时未处理的“错误”事件

Question

I follower every instruction for installing a MEAN stack application.

At the end of it all I run grunt and when I go to http://localhost:3000 I get the following error:

Running "clean:0" (clean) task

Running "jshint:all" (jshint) task
>> 47 files lint free.

Running "csslint:src" (csslint) task
>> 5 files lint free.

I searched and found this answer , but this does not seem to be the case, when I run ps aux | grep node ps aux | grep node I dont get any running process:

trufa    14763  0.0  0.0  23492   956 pts/14   S+   15:39   0:00 grep --color=auto node

I searched through many answers but none seem to apply. Some suggest to change the port . I tried it and the error is the same.

Any suggestions as to how to proceed?

Answer 1

Sometimes the automatic bower install does not work if you run npm with sudo.

1. I would recommend setting up npm so it does not require sudo .
2. Try running $ bower install from your project root, and then restart the server.

Answer 2

您已使用相同的端口8080运行另一台服务器。
