1.卸载自动Python
# rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps
2删除残余文件
# whereis python |xargs rm -frv
例如 python 3.6 安装带python3.6m
./configure --prefix=/usr/local/python3 --enable-shared CFLAGS=-fPIC
make && make install
生成 (/usr/local/python3) libpython3.6m.so和libpython3.6m.so.1.0
./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
make && make install
生成 (/usr/local/python3) libpython3.6m.a
ln -s /usr/local/python/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python/bin/pip3 /usr/bin/pip3
