pip _blocking_errnos = {errno.EAGAIN, errno.EWOULDBLOCK}

问题

使用pip install 出现以下错误信息:

Traceback (most recent call last):
  File "/usr/bin/pip", line 7, in <module>
    from pip._internal import main
  File "/usr/lib/python2.6/site-packages/pip/_internal/__init__.py", line 19, in <module>
    from pip._vendor.urllib3.exceptions import DependencyWarning
  File "/usr/lib/python2.6/site-packages/pip/_vendor/urllib3/__init__.py", line 8, in <module>
    from .connectionpool import (
  File "/usr/lib/python2.6/site-packages/pip/_vendor/urllib3/connectionpool.py", line 92
    _blocking_errnos = {errno.EAGAIN, errno.EWOULDBLOCK}
                                    ^
                                    SyntaxError: invalid syntax

解决

# 1， 从官方github获取具体版本的pip
wget  https://raw.githubusercontent.com/pypa/get-pip/master/2.6/get-pip.py
# 2，运行刚才获取的pip文件
python2.6 get-pip.py

测试

pip -V
pip 9.0.3 from /usr/lib/python2.6/site-packages (python 2.6)
