解决 AttributeError: ‘module’ object has no attribute ‘SSL_ST_INIT’

有台机器好久未登录了，今天执行pip的时候报错如下：AttributeError: ‘module’ object has no attribute ‘SSL_ST_INIT’，鼓捣了半天终于搞定。

环境： python2.7
网上搜索了下，应该是pyOpenSSL模块的问题，因为pip执行报错，需要先删除这个模块，重新安装即可，具体操作如下：

sudo rm -rf /usr/lib/python2.7/dist-packages/OpenSSL/
sudo rm -rf /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info

pip重新安装pyopenssl时又报错

sudo pip install pyopenssl
Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)

解决办法：

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

再次安装pyopenssl，这次成功了。

sudo pip install pyopenssl
