ModuleNotFoundError: No module named ‘_ctypes‘解决方法

如果你动过已配置在系统中的Python2的话

请将其恢复原样。 如果没有动过请跳过第1项。

1.重新安装Python2

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install python2 python2-dev python2.7-dev

2.执行如下的命令处理_ctypes的错误

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev

3.安装完毕之后，重新编译并安装Python3

./configure --enable-optimizations
#一定要用 --enable-optimizations这个命令

make && make install

4.pip3安装自己之前想安装的

python3 -m pip install --upgrade pip
pip3 install [module]
