Tox在几周前运行得很好，但是我回到了一个使用Tox运行测试的项目，现在它总是需要30秒才能运行。我认为这可能是对项目进行更改的问题，但我在其他项目中尝试过tox(甚至是hello world测试)，它们都需要30秒才能运行。

它就像在30秒超时，然后它只是正常运行测试。我尝试使用ls -lah作为命令和配置文件tox，我得到了这些结果http://pastebin.com/EtQh3Xhq。
我正在运行OSX Yosemite 10.10.5Python和tox版本
$ python --version
Python 2.7.10
$ tox --version
2.3.1 imported from /Library/Python/2.7/site-packages/tox/__init__.pyc
我尝试过有或没有setup.py的项目，或多或少的环境，我总是得到同样的慢时间。有人知道是怎么回事，怎么解决吗?
删除安装在$HOME/目录下的旧包。托克斯解决了这个问题。看起来30秒是由于boto超时造成的，其中一些包使用了boto。不知道为什么会这样
