Create shims for all installed executables (such as: ~/.pyenv/versions/*/bin/* ), so you should perform this command every time you delete a Python version or a package with an executable file (such as PIP)
$ pyenv install 2.7.3$ pyenv rehash
Pyenv Global
Sets the global version of Python by how the version number is written to ~/.pyenv/version the file.
$ pyenv global3.4.0
Pyenv Local
Sets the local version for the program, by how the version number is written to the file in the current directory .python-version . The Python version set in this way has a higher priority than global. Pyenv will search the file up and down from .python-version the current directory until the root directory has been reached. If you can't find it, use the global version.
$ pyenv local2.7.3
Pyenv Shell
Sets the Python version for Shell, by setting the current shell's PYENV_VERSION environment variables. This version has a higher priority than both local and global. --unsetparameter can be used to cancel the current shell set version.
$ pyenv shell pypy-2.2.1$ pyenv shell--unset
