2、解决：python ModuleNotFoundError: No module named '_ctypes'
3.7版本需要一个新的包libffi-devel，安装此包之后再次进行编译安装即可。 yum install libffi-devel -y
3、安装pip3
1.首先安装setuptools wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26 tar -zxvf setuptools-19.6.tar.gz cd setuptools-19.6.tar.gz python3 setup.py build python3 setup.py install 2.然后直接安装pip就搞定了。。 wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb tar -zxvf pip-8.0.2.tar.gz cd pip-8.0.2 python3 setup.py build python3 setup.py install
