Python开发环境之pyenv环境搭建

  首先到Github上下载Pyenv相应的一键安装脚本,

  安装完毕,设置环境变量,设置环境变量,可以添加到个人家目录的.bashrc或.bash_profile及系统的全局的/etc/profile,

  # Load pyenv automatically by adding

  # the following to ~/.bash_profile:

  export PATH="/home/lavenliu/.pyenv/bin:$PATH"

  eval "$(pyenv init -)"

  eval "$(pyenv virtualenv-init -)"

  设置完毕之后,可以在命令行进行验证,

  [lavenliu@VM_113_230_centos ~]$ . ~/.bash_profile

  [lavenliu@VM_113_230_centos ~]$ pyenv

  pyenv 20160726

  Usage: pyenv []

  Some useful pyenv commands are:

  commands List all available pyenv commands

  local Set or show the local application-specific Python version

  global Set or show the global Python version

  shell Set or show the shell-specific Python version

  install Install a Python version using python-build

  uninstall Uninstall a specific Python version

  rehash Rehash pyenv shims (run this after installing executables)

  version Show the current Python version and its origin

  versions List all Python versions available to pyenv

  which Display the full path to an executable

  whence List all Python versions that contain the given executable

  See `pyenv help ' for information on a specific command.

  以上都没有问题。比如,安装一个3.5.2的版本Python,

  pyenv install 3.5.2

  如果下载速度慢的话,可以事先下载之,放到~/.pyenv/cache目录即可。修改~/.pyenv/plugins/python-build/share/python-build/3.5.2文件,

  cat ~/.pyenv/plugins/python-build/share/python-build/3.5.2

  #require_gcc

  install_package "openssl-1.0.2g" "https://www.openssl.org/source/openssl-1.0.2g.tar.gz#b784b1b3907ce39abf4098702dade6365522a253ad1552e267a9a0e89594aa33" mac_openssl --if has_broken_mac_openssl

  install_package "readline-6.3" "http://ftpmirror.gnu.org/readline/readline-6.3.tar.gz#56ba6071b9462f980c5a72ab0023893b65ba6debb4eeb475d7a563dc65cafd43" standard --if has_broken_mac_readline

  if has_tar_xz_support; then

  install_package "Python-3.5.2" "~/.pyenv/cache/Python-3.5.2.tar.gz" ldflags_dirs standard verify_py35 ensurepip

  else

  install_package "Python-3.5.2" "~/.pyenv/cache/Python-3.5.2.tar.gz" ldflags_dirs standard verify_py35 ensurepip

  由于没有~/.pyenv/cache目录,进行手工创建,

  $ mkdir ~/.pyenv/cache

  如果使用手工安装,则需要安装一些依赖,

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

  需要事先准备好Python-3.5.2.tar.gz的安装包,放到~/.pyenv/cache目录下。然后,在命令行直接使用pyenv install 3.5.2即可,

  $ pyenv install 3.5.2

  安装完毕,使用version命令进行查看,

  pyenv version

  3.5.2 (set by /home/lavenliu/.python-version)

  至此,就安装完毕了。
