报错：python setup.py egg_info Check the logs for full comm

部署WPS云文档的时候，出现以下错误：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

去百度搜索了一下，说是Python2.7版本太老了，附上升级Python3以上版本的方式：

1.安装前查看当前系统下的python版本号

# python -V

2.获取python3.x的官方软件包

# wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

3.解压缩该软件包

# tar -zxvf Python-3.6.5.tgz

4.在解压目录下安装配置

# cd Python-3.6.5
# ./configure

5.编译并安装

# make
# make install

发现..还是不行，竟然还是提示我用的是Python2.7，那就是WPS那个安装程序的问题了..

继续寻找解决方式

最后官方给出了解决方法：
