【问题描述】：

当我在 AWS Ubuntu 中生产我的项目时，我想使用 Fabric。当我阅读 Fabric 时，它需要 python 2.5~2.7，所以我在 Mac OS X 上创建了 Python virtualenv：

pyenv virtualenv 2.7.5 fabric
mkdir fabric

然后我运行pip install fabric

(fabric)fabric $ pip install fabric

但它有 2 个错误

Collecting fabric

有人告诉我“你应该安装 pycrpto”，所以我安装了 pycrpto

pip install pycrpto

但是当我pip install fabric 时它有同样的错误。我找到了这个解决方案link，所以我运行：

brew install gmp
export LIBRARY_PATH=/usr/local/lib
pip install pycrypto

但它有同样的错误，第二个解决方案是link

$ bunzip2 gmp-5.0.5.tar.bz2

但它还有另一个错误：

bunzip2: Can't open input file gmp-5.0.5.tar.bz2: No such file or directory. 

我不明白为什么 Fabric 无法安装...

【问题讨论】：

可能不是核心问题，但请注意'pycrpto' != 'pycrypto'

嗯....谢谢！但是pip install pycrypto 也不起作用

哦....我的错误...fabric可以安装2.5 < fabric ver < 2.7我使用pyenv 2.6.7我解决了我的问题！

【参考方案1】：

这是 Python pyenv#273。

你可以通过修补_sysconfigdata.py来修复它：

$ export p=/Users/andrei/.pyenv/versions/2.7.6
$ sed -i -e "s#python.exe#$p/bin/python2.7#g" "$p/lib/python2.7/_sysconfigdata.py"
