# Command Reference
|
|
|
|
Like `git`, the `pyenv` command delegates to subcommands based on its
|
|
first argument.
|
|
|
|
The most common subcommands are:
|
|
|
|
* [pyenv local](#pyenv-local)
|
|
* [pyenv global](#pyenv-global)
|
|
* [pyenv shell](#pyenv-shell)
|
|
* [pyenv versions](#pyenv-versions)
|
|
* [pyenv version](#pyenv-version)
|
|
* [pyenv rehash](#pyenv-rehash)
|
|
* [pyenv which](#pyenv-which)
|
|
* [pyenv whence](#pyenv-whence)
|
|
|
|
|
|
|
|
## pyenv local
|
|
|
|
Sets a local application-specific Python version by writing the version
|
|
name to a `.python-version` file in the current directory. This version
|
|
overrides the global version, and can be overridden itself by setting
|
|
the `PYENV_VERSION` environment variable or with the `pyenv shell`
|
|
command.
|
|
|
|
$ pyenv local 2.7.6
|
|
|
|
When run without a version number, `pyenv local` reports the currently
|
|
configured local version. You can also unset the local version:
|
|
|
|
$ pyenv local --unset
|
|
|
|
Previous versions of pyenv stored local version specifications in a
|
|
file named `.pyenv-version`. For backwards compatibility, pyenv will
|
|
read a local version specified in an `.pyenv-version` file, but a
|
|
`.python-version` file in the same directory will take precedence.
|
|
|
|
|
|
### pyenv local (advanced)
|
|
|
|
You can specify multiple versions as local Python at once.
|
|
|
|
Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
|
|
|
|
$ pyenv local 2.7.6 3.3.3
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by /Users/yyuu/path/to/project/.python-version)
|
|
* 3.3.3 (set by /Users/yyuu/path/to/project/.python-version)
|
|
$ python --version
|
|
Python 2.7.6
|
|
$ python2.7 --version
|
|
Python 2.7.6
|
|
$ python3.3 --version
|
|
Python 3.3.3
|
|
|
|
or, if you prefer 3.3.3 over 2.7.6,
|
|
|
|
$ pyenv local 3.3.3 2.7.6
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by /Users/yyuu/path/to/project/.python-version)
|
|
* 3.3.3 (set by /Users/yyuu/path/to/project/.python-version)
|

|
## pyenv global
|
|
|
|
Sets the global version of Python to be used in all shells by writing
|
|
the version name to the `~/.pyenv/version` file. This version can be
|
|
overridden by an application-specific `.python-version` file, or by
|
|
setting the `PYENV_VERSION` environment variable.
|
|
|
|
$ pyenv global 2.7.6
|
|
|
|
The special version name `system` tells pyenv to use the system Python
|
|
(detected by searching your `$PATH`).
|
|
|
|
When run without a version number, `pyenv global` reports the
|
|
currently configured global version.
|
|
|
|
|
|
### pyenv global (advanced)
|
|
|
|
You can specify multiple versions as global Python at once.
|
|
|
|
Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
|
|
|
|
$ pyenv global 2.7.6 3.3.3
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by /Users/yyuu/.pyenv/version)
|
|
* 3.3.3 (set by /Users/yyuu/.pyenv/version)
|
|
$ python --version
|
|
Python 2.7.6
|
|
$ python2.7 --version
|
|
Python 2.7.6
|
|
$ python3.3 --version
|
|
Python 3.3.3
|
|
|
|
or, if you prefer 3.3.3 over 2.7.6,
|
|
|
|
$ pyenv global 3.3.3 2.7.6
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by /Users/yyuu/.pyenv/version)
|
|
* 3.3.3 (set by /Users/yyuu/.pyenv/version)
|
|

|
$ python3.3 --version
|

|
|
|
|
|
|
## pyenv shell
|
|
|
|
Sets a shell-specific Python version by setting the `PYENV_VERSION`
|
|
environment variable in your shell. This version overrides
|
|
application-specific versions and the global version.
|
|
|
|
$ pyenv shell pypy-2.2.1
|
|
|
|
When run without a version number, `pyenv shell` reports the current
|
|
value of `PYENV_VERSION`. You can also unset the shell version:
|
|
|
|
$ pyenv shell --unset
|
|
|
|
Note that you'll need pyenv's shell integration enabled (step 3 of
|
|
the installation instructions) in order to use this command. If you
|
|
prefer not to use shell integration, you may simply set the
|
|
`PYENV_VERSION` variable yourself:
|
|
|
|
$ export PYENV_VERSION=pypy-2.2.1
|
|
|
|
|
|
### pyenv shell (advanced)
|
|
|
|
You can specify multiple versions via `PYENV_VERSION` at once.
|
|
|
|
Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
|
|
|
|
$ pyenv shell 2.7.6 3.3.3
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by PYENV_VERSION environment variable)
|
|
* 3.3.3 (set by PYENV_VERSION environment variable)

|
|
|
|
or, if you prefer 3.3.3 over 2.7.6,
|
|
|
|
$ pyenv shell 3.3.3 2.7.6
|
|
$ pyenv versions
|
|
system
|
|
* 2.7.6 (set by PYENV_VERSION environment variable)
|
|
* 3.3.3 (set by PYENV_VERSION environment variable)
