setup.py入门

记录安装路径

增加 –record 参数重新安装软件包，执行命令：
python ./setup.py install --record install.txt

根据记录的安装路径删除

删除安装文件，执行命令：
cat install.txt | xargs rm -rf

--record install.txt选项，使安装包信息记录到文件中，文件内容：

/usr/lib64/python2.7/site-packages/UNKNOWN-0.0.0-py2.7-linux-x86_64.egg

总结：

setup会
（1）编译c/c++文件成.so文件
（2）编译py文件成py文件
（3）生成元信息
（4）将上述文件打包成egg格式，然后拷贝到/usr/lib64/python2.7/site-packages/路径中
（5）相应安装包的信息记录在--record指定的文本文件中。
