centos 7 编译 python3.7.0，centospython3.7.0,安装编译所需库yum

yum install -y libffi-devel

编译安装

cd /usr/local/srcwget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgztar zxf Python-3.7.0.tgzcd Python-3.7.0./configure --prefix=/usr/local/python370make && make install

若修改默认python，yum会出问题，故添加环境变量PATH

不能修改默认

unlink /usr/bin/pythonln -s /usr/local/python370/bin/python3 /usr/bin/python

/etc/profile添加PATH
PATH=$PATH:/usr/local/python370/bin

注意

报错

File "/usr/local/src/Python-3.7.0/Lib/ctypes/__init__.py", line 7, in <module>    from _ctypes import Union, Structure, ArrayModuleNotFoundError: No module named ‘_ctypes‘make: *** [install] Error 1

安装libffi-devel即可
