python setup.py Egg_info gcc 安装 cassandra python 时出错

Question

由于某种原因，我需要手动安装的具体版本无法直接访问:

  rpm -i ftp://195.220.108.108/linux/centos/7.1.1503/updates/x86_64/Packages/python-2.7.5-18.el7_1.1.x86_64.rpm

因此尝试了全新的 python 安装，然后尝试更新和安装安装工具

yum -y update
yum -y install python-pip
pip install -U pip
pip install -U setuptools
pip install cassandra-driver
yum install patch

然后尝试

  wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
  python ez_setup.py
  pip install cassandra-driver

完整的堆栈跟踪

太早输入 Enter，错过了 gcc 库并被类似的帖子冲昏了头脑。

/tmp/easy_install-N19BCp/Cython-0.23.4/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
 #include "Python.h"
                    ^
compilation terminated.
Unable to find pgen, not compiling formal grammar.
Traceback (most recent call last):

然后python-devel解决了这个问题。

install yum install python-devel
