cocos run -p web 报错
这个问题好像没出现过。楼主能否贴出setup.py的配置信息以供排查错误呢
setup.py

This script will install environment variables needed to by cocos2d-x. It will set these envrironment variables:
* COCOS_CONSOLE_ROOT: used to run cocos console tools, more information about cocos console tools please refer to
https://github.com/cocos2d/cocos2d-console
* NDK_ROOT: used to build android native codes
* ANDROID_SDK_ROOT: used to generate applicatoin on Android through commands
* ANT_ROOT: used to generate applicatoin on Android through commands
On Max OS X, when start a shell, it will read these files and execute commands in sequence:
~/.bash_profile
~/.bash_login
~/.profile
And it will read only one of them. So we will add environment variable in the same sequence.
Which means that
* add environment variables into ~/.bash_profile if it exists
* otherwise it will the add environment variables into ~/.bash_login if it exists
* otherwise it will the add environment variables into ~/.profile if it exists
Will create ~/.bash_profile when none of them exist, and add environment variables into it.

执行cocos run -p web时，由于ie浏览器第一次加载很慢，然后刷新页面就出现了错误，
还有多次执行cocos run -p web时，浏览器都是显示黑色背景，没有其他内容
cmd 运行setup.py的图片
现在在笔记本上执行cocos run -p web时还出现了图下的错误
你好，对于 python 的服务器启动我也不是很熟悉。
在网上查了一下，可能有这样几个原因：
- 防火墙设置阻止了端口的使用。
- 当前用户没有启动该服务器端口的权限。（可以尝试一下其他端口。在 run 命令的最后加上端口号参数。如：cocos run -p web 9999）
对于楼主的帖子中所报的错误，没有什么想法。不知道什么原因。
问题基本解决了
由于之前是运行setup.py来绑定ant、SDK、ndk环境，当电脑重启后再运行setup.py会提示sdk未绑定，后来我根据这个http://blog.sina.com.cn/s/blog_a81f7ba90101k1cf.html解决了问题，
现在执行cocos run -p web时，如果浏览器显示是黑屏或网页打不开，就多执行几次cocos run -p web，浏览器基本都会正常显示内容了
谢谢反馈:867:
我的也出现了，换了个port 好了。不知道IDE中如何换port
