python2.6 使用pip安裝django報錯

以前處理過這個問題，由於沒有記錄，因此第二次踩坑了，因此這次留存處理記錄

centos6.五、默認的python2.六、pip1.5.4

安裝django

pip install django

執行結果：

 懷疑是沒裝setuptools

install --upgrade pip setuptools

繼續安裝django嘗試....報錯

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 42, in <module>
    from pip._internal import cmdoptions

    from pip._internal.index import (
  File "/usr/lib/python2.6/site-packages/pip/_internal/index.py", line 536
    {str(c.version) for c in all_candidates},

這個報錯就比較明顯了

是python版本問題，由於默認的2.6不支持，最低要求2.7，因此升級2.7以後解決。
