求助！关于Bottle+python运行时错误的问题，详情请进

[iscien]

环境python 3.3.2+bottle 0.11.6+win7 专业版
刚开始学python 和bottle ,用pip安装了bottle,试着写了一个小程序，有一段时间还一切OK，但最近发现第一次打开的时候很长时间没有反应，重新刷新一次就OK了，但终端出现好多的错误提示。电脑没有其它变化，bottle是用pip安装的。
将debug=True改为False之后依然如故，请各位指点，多谢！

from bottle import route,run

@route('/')
def hello():
    return "Hello World!"

run(host='localhost', port=8080, debug=True)

详细讲讲怎么才能触发你得到的异常。我这儿允许你的程序没有任何问题。

奇怪今天在WinXP下试一试却一切正常，难道是win7的问题？
