当编译安装的python导入types模块出错时，一般是编译安装python之前没有安装libffi-devel。报错信息如下：
# python
Python 3.7.5 (default, Nov 3 2020, 14:56:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/python37/lib/python3.7/ctypes/__init__.py", line 7, in <module>
from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'
>>>
这里需要安装libffi-devel，重新编译安装python。执行命令如下：
yum install libffi-devel -y ----需要换成默认的python，否则会yum报错
cd Python-3.7.5/
make clean && make && make install
