PYENV environment construction of python development environment

First download pyenv the corresponding one-click installation script to GitHub,

$ curl-l Https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | Bash

After installation, setting environment variables, setting environment variables, can be added to the personal home directory of the. bashrc or. Bash_profile and the system's full
Bureau of/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-)"

Once setup is complete, you can verify it at the command line,

[[email protected]_113_230_centos ~]$ . ~/.bash_profile   [[email  Protected]_113_230_centos ~]$ pyenv pyenv 20160726usage: 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 executableSee  ' pyenv  help <command> '  for information on a specific command.

None of the above is a problem. For example, install a 3.5.2 version of Python,

Pyenv Install 3.5.2

If the download speed is slow, you can download it in advance and put it in the ~/.pyenv/cache directory. Modify the ~/.pyenv/plugins/python-build/share/python-build/3.5.2 file,

Cat ~/.pyenv/plugins/python-build/share/python-build/3.5.2#require_gccinstall_package "openssl-1.0.2g" "https:// Www.openssl.org/source/openssl-1.0.2g.tar.gz#b784b1b3907ce39abf4098702dade6365522a253ad1552e267a9a0e89594aa33 " Mac_openssl--if has_broken_mac_opensslinstall_package "readline-6.3" "http://ftpmirror.gnu.org/readline/ Readline-6.3.tar.gz#56ba6071b9462f980c5a72ab0023893b65ba6debb4eeb475d7a563dc65cafd43 "Standard--if Has_broken_ Mac_readlineif Has_tar_xz_support; Then Install_package "Python-3.5.2", "~/.pyenv/cache/python-3.5.2.tar.gz" Ldflags_dirs standard verify_py35 Ensurepipelse install_package "Python-3.5.2" "~/.pyenv/cache/python-3.5.2.tar.gz" Ldflags_dirs standard verify_py35 Ensurepipfi

Because there is no ~/.pyenv/cache directory, it is created manually,

$ mkdir ~/.pyenv/cache

If you use manual installation, you need to install some dependencies,

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

The python-3.5.2.tar.gz installation package needs to be prepared in advance and placed in the ~/.pyenv/cache directory. Then, use the Pyenv install 3.5.2 directly on the command line,

$ pyenv Install 3.5.2

After installation, use the version command to view the

Pyenv version3.5.2 (set by/home/lavenliu/.python-version)

At this point, the installation is complete.
