2、安装python3过程中报错
no acceptable C compiler found in $PATH
参考

yum -y install gcc
3、安装python3过程中保存：执行make install时
关键错误：zipimport.ZipImportError: can't decompress data
详细错误：
Traceback (most recent call last):
File "/root/Desktop/software/Python-3.6.4/Lib/runpy.py", line 193, in _run_module_as_main

4、建立命令的快捷方式。和https://www.cnblogs.com/lclq/archive/2016/06/27/5620196.html教程有区别
python3
ln -s /usr/local/python/python3/bin/python3 /usr/bin/python3
pip3
ln -s /usr/local/python/python3/bin/pip3 /usr/bin/pip3
进入python的安装文件夹。执行
.configure --prefix=/usr/local/python3 && make && make install
