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
