linux升级Python 2.7.14后pip功能报错的解决方法

小樱

Could not find a version that satisfies the requirement tempora==1.8 (from flexget) (from versions: 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.6.1)
No matching distribution found for tempora==1.8 (from flexget)
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

[root@207 ~]# pip -V
pip 9.0.2 from /usr/lib/python2.6/site-packages (python 2.6)
[root@207 ~]# python -V
Python 2.7.14

大概，，问题应该是pip用了2.6的，和2.7的不通用导致的一个问题
试过pip install --upgrade pip也没有用

折腾了一下又出现一个新的错误
[root@207 ~]# pip install --upgrade pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip
[root@207 ~]#


解决方案

1. wget https://bootstrap.pypa.io/get-pip.py
   
2. python get-pip.py
   
3. mv /usr/bin/pip /usr/bin/pip.bak
   
4. ln -s /usr/local/bin/pip2.7 /usr/bin/pip
   

复制代码

再次打印
[root@207 ~]# pip -V
pip 9.0.2 from /usr/local/lib/python2.7/site-packages (python 2.7)
[root@207 ~]#

已经成功切换到了2.7版本的pip，测试，pip的各种使用问题成功解决
