升级到最新的stable后,python的pip还是老的. 在安装一些包的时候,报错了
Traceback (most recent call last): File "/usr/bin/pip", line 9, in <module> load_entry_point('pip==1.5.6', 'console_scripts', 'pip')() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 356, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2476, in load_entry_point return ep.load() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2190, in load ['__name__']) File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 74, in <module> from pip.vcs import git, mercurial, subversion, bazaar # noqa File "/usr/lib/python2.7/dist-packages/pip/vcs/mercurial.py", line 9, in <module> from pip.download import path_to_url File "/usr/lib/python2.7/dist-packages/pip/download.py", line 22, in <module> import requests, six File "/usr/local/lib/python2.7/dist-packages/requests-2.4.3-py2.7.egg/requests/__init__.py", line 53, in <module> from .packages.urllib3.contrib import pyopenssl File "/usr/local/lib/python2.7/dist-packages/requests-2.4.3-py2.7.egg/requests/packages/urllib3/contrib/pyopenssl.py", line 73, in <module> ssl.PROTOCOL_SSLv3: OpenSSL.SSL.SSLv3_METHOD,AttributeError: 'module' object has no attribute 'PROTOCOL_SSLv3'原因是debian8的pip用了urllib3, 而urllib3使用了debian8的新编译的OpenSSL SSLv3版.
修复很简单, 升级pip,
pip install requests==2.6.0
或者
easy_install --upgrade pip然后就可以pip install 安装了
