今天在本地运行micolog出现错误regex invalid: unbalanced parenthesis上网搜了下，终于在一篇英文里找到解决方法。

Change lines 2369-70 in <installdir>\google\appengine\tools\dev_appserver.py from: 

1
2
regex = os.path.join(re.escape(regex), '(.*)') 
path = os.path.join(path, '\\1')

to: 

1
2
regex = re.escape(regex) + '/(.*)' 
path = path + '/\\1'

这个问题决之后竟然又出现错误

这次是怎么也搞不定了，google一下竟然就只有十几个页面，而且都和这没关系。期待谁能帮我解决下啊。
