本文主要是介绍在CentOS6上安装Python2.7的解决方法,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
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
cat /etc/*-release
发现系统版本为CentOS6,于是开始Google搜索怎么解决。
解决办法
重新手动装一个Python2.7
准备阶段
# 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
安装Python
下载python2.7并安装
# Get Python 2.7.14: wget http://python.org/ftp/python/2.7.14/Python-2.7.14.tar.xz tar xf Python-2.7.14.tar.xz cd Python-2.7.14 ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" make && make altinstall
安装Pip
# First get the script: wget https://bootstrap.pypa.io/get-pip.py # Then execute it using Python 2.7 python2.7 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)
# Install virtualenv for Python 2.7 and create a sandbox called my27project: pip2.7 install virtualenv virtualenv my27project 试一下? # Check the system Python interpreter version: python --version # This will show Python 2.6.6 # Activate the my27project sandbox: source my27project/bin/activate # This will show Python 2.7.4 python --version
