pyenv环境安装以及国内源

一键安装脚本

#[https://github.com/pyenv/pyenv-installer](https://github.com/pyenv/pyenv-installer)
curl https://pyenv.run | bash
#如果有提示添加pyenv失败，请在.bashrc自行添加下面三行内容：
export PATH="~/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

国内源加速

#pyenv install --list  查看你想要的版本，然后替换v的变量即可。
v=3.5.2;wget http://mirrors.sohu.com/python/$v/Python-$v.tar.xz -P ~/.pyenv/cache/;pyenv install $v

编译python失败的话，安装依赖即可。
