安装python oss2

1.  源码安装，过程忽略，遇到安装后无法import oss2 的情况；

2. 选择sudo pip install oss2

遇到问题1:

File "/usr/local/lib/python2.7/distutils/dist.py", line 1154, in _encode_field
        if isinstance(value, unicode):
    RuntimeError: maximum recursion depth exceeded while calling a Python object
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-ijohkq/oss2/

解决办法：sudo vim /usr/local/lib/python2.7/distutils/dist.py

在这个文件开头新增

import sys   
sys.setrecursionlimit(1000000) #例如这里设置为一百万  

遇到问题2：

Command "python setup.py egg_info" failed with error code -11 in /tmp/pip-install-SS9ri9/oss2/

解决办法：

sudo python -m pip install --upgrade --force pip 
sudo pip install setuptools==33.1.1
