Python 环境部署

yum -y install git gcc make patch zlib-devel gdbm-devel openssl-devel sqlite-devel bzip2-devel readline-devel

普通用户下：

curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
cat >> ~/.bash_profile <<EOF
export PATH="\$HOME/.pyenv/bin:\$PATH"
eval "\$(pyenv init -)"
eval "\$(pyenv virtualenv-init -)"
EOF
source ~/.bash_profile  
exec $SHELL

#pyenv update

pyenv install 3.5.3 -v
pyenv virtualenv 3.5.3 py35

mkdir projects && cd projects
pyenv local py35
pyenv version

mkdir ~/.pip
cat > ~/.pip/pip.conf << EOF

常用命令

pyenv install --list # 列出可安装版本
pyenv install <version> # 安装对应版本
pyenv install -v <version> # 安装对应版本，若发生错误，可以显示详细的错误信息
pyenv versions # 显示当前使用的python版本
pyenv which python # 显示当前python安装路径
pyenv global <version> # 设置默认Python版本
pyenv local <version> # 当前路径创建一个.python-version, 以后进入这个目录自动切换为该版本
pyenv shell <version> # 当前shell的session中启用某版本，优先级高于global 及 local

使用virtualenv

pyenv virtualenv env # 从默认版本创建虚拟环境
pyenv virtualenv 3.6.4 env-3.6.4 # 创建3.6.4版本的虚拟环境
pyenv activate env-3.6.4 # 激活 env-3.6.4 这个虚拟环境
pyenv deactivate # 停用当前的虚拟环境

自动激活
使用pyenv local 虚拟环境名
会把`虚拟环境名`写入当前目录的.python-version文件中
关闭自动激活 -> pyenv deactivate
启动自动激活 -> pyenv activate env-3.6.4
pyenv local env-3.6.4

pyenv uninstall env-3.6.4 # 删除 env-3.6.4 这个虚拟环境
