CentOS 6.5安装Python2.7.14(2)

至此，新版 Python 即算安装完毕了。
注意：这可能会导致以前安装过的 Python 程序运行不了或者无法重启之类的（比如著名的 Shadowsocks Python 版）。原因是旧版的 pkg_resources 位于 /usr/lib/python2.6/site-packages 下。而新版的则是在 /usr/local/lib/python2.7/site-packages 下。
所以，我们需要将python2.6下site-packages目录中的文件拷贝到python2.7/site-packages下。

cp -r /usr/lib/python2.6/site-packages/yum /usr/local/lib/python2.7/site-packages/ 
cp -r /usr/lib/python2.6/site-packages/rpmUtils /usr/local/lib/python2.7/site-packages/ 
cp -r /usr/lib/python2.6/site-packages/iniparse /usr/local/lib/python2.7/site-packages/ 
cp -r /usr/lib/python2.6/site-packages/urlgrabber /usr/local/lib/python2.7/site-packages/ 
cp -r /usr/lib64/python2.6/site-packages/rpm /usr/local/lib/python2.7/site-packages/ 
cp -r /usr/lib64/python2.6/site-packages/curl /usr/local/lib/python2.7/site-packages/ 
cp -p /usr/lib64/python2.6/site-packages/pycurl.so /usr/local/lib/python2.7/site-packages/ 
cp -p /usr/lib64/python2.6/site-packages/_sqlitecache.so /usr/local/lib/python2.7/site-packages/ 
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.py /usr/local/lib/python2.7/site-packages/ 
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.pyc /usr/local/lib/python2.7/site-packages/ 
cp -p /usr/lib64/python2.6/site-packages/sqlitecachec.pyo /usr/local/lib/python2.7/site-packages/
