我刚刚couchapp按照说明安装并完成了入门教程。当我运行时，couchapp push我收到这样的错误：
2012-06-23 14:05:08 [CRITICAL] unknown error [[Errno 22] Invalid argument]

我在 OS X 10.6.8 上，CouchDB 已经由管理员设置，并且.couchapprc文件的默认数据库设置为http://user:pass@localhost:5984/mydb. 我已按照couchapp.org的说明进行 Homebrew 安装。我唯一能想到的是这是一个与 Python 相关的问题，但我不了解 Python，似乎无法弄清楚为什么这件事会失败。任何帮助追踪此问题并解决它将不胜感激。
谢谢。
