我读了很多关于这个错误的帖子，我发布这个的原因是因为我在试图安装statmodels包时得到了错误，而不是我的一个程序。
如何纠正安装包时的错误?

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/statsmodels
读到建议的回答，我跑了:
sudo pip3 install numpy --upgrade
Requirement already up-to-date: numpy in /usr/local/lib/python3.2/dist-packages

卸载了matplotlib和numpy，然后再次安装时，我得到以下消息:
sudo pip3 install matplotlib
Requirement already satisfied (use --upgrade to upgrade): matplotlib in /usr/local/lib/python3.2/dist-packages
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.5 in /usr/lib/python3/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /usr/local/lib/python3.2/dist-packages/python_dateutil-2.2-py3.2.egg (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): tornado in /usr/local/lib/python3.2/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): pyparsing>=1.5.6 in /usr/local/lib/python3.2/dist-packages/pyparsing-2.0.2-py3.2.egg (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): nose in /usr/local/lib/python3.2/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): six in /usr/local/lib/python3.2/dist-packages/six-1.7.2-py3.2.egg (from python-dateutil->matplotlib)
Cleaning up...
对于numpy，重新安装返回以下内容:
sudo pip3 install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/lib/python3/dist-packages

这是Python 3.*中numpy遇到的一个错误。它似乎已经在源代码中修复了，但我不知道它是否发现自己已经发布了。
请先升级numpy再安装statsmodel。
在Python 2中。， .keys()函数将返回一个列表，但在3。返回一个迭代器，这就是bug的原因。
