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，
$ curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash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 <command> [<args>]
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 <command>' for information on a specific command.
For full documentation, see: https://github.com/yyuu/pyenv#readme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
fi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，已经安装完毕。
