今天在虚拟机安装 Python3 的时候遇到下面的报错：

File "/usr/local/lib/python3.7/multiprocessing/sharedctypes.py", line 10, in <
module>
   import ctypes
   File "/usr/local/lib/python3.7/ctypes/__init__.py", line 7, in <module>
      from _ctypes import Union, Structure, Array
ImportError: No module named '_ctypes'

解决方案

# RHEL/Fedora/CentOS
sudo yum install libffi-devel
---
# Debian/Ubuntu:
sudo apt-get install libffi-dev
