在CentOS6上yum安装工具是基于Python2.6.6的，所以在CentOS6上默认安装的是Python2.6.6，因为要在服务器系统为CentOS6上部署生产环境，但是代码都是基于Python2.7写的，所有遇到了问题。
探索
发现系统不能卸载Python2.6后，查了系统的版本号

# Start by making sure your system is up-to-date:yum update# Compilers and related tools:yum groupinstall -y "development tools"# Libraries needed during compilation to enable all features of Python:yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel# If you are on a clean "minimal" install of CentOS you also need the wget tool:yum install -y wget |

# First get the script:wget https://bootstrap.pypa.io/get-pip.py# Then execute it using Python 2.7python2.7 get-pip.py# With pip installed you can now do things like this:pip2.7 install [packagename]pip2.7 install --upgrade [packagename]pip2.7 uninstall [packagename] |
创建虚拟环境
最后可以利用venv创建一个虚拟环境（毕竟Python2.6你不能卸载）
