编译遇见的错误
安装出现如下错误
Ansible now needs setuptools in order to build. Install it using your package manager (usually python-setuptools) or via pip (pip install setuptools).
查看setup.py的内容
try:
from setuptools import setup, find_packages
from setuptools.command.build_py import build_py as BuildPy
from setuptools.command.install_lib import install_lib as InstallLib
from setuptools.command.install_scripts import install_scripts as InstallScripts
except ImportError:
print("Ansible now needs setuptools in order to build. Install it using"

Python3中有个内置?？榻衏types，它是Python3的外部函数库?？椋峁┘嫒軨语言的数据类型，并通过它调用Linux系统下的共享库(Shared library)。由于在CentOS7系统中没有安装外部函数库(libffi)的开发链接库软件包，因此我们需要手动安装并重新编译python
$ yum install libffi-devel -y
$ make && make install -j 4
