# Summary: Set or show the local application-specific Python version
|
|
#
|
|
# Usage: pyenv local <version>
|
|
# pyenv local --unset
|
|
#
|
|
# Sets the local application-specific Python version by writing the
|
|
# version name to a file named `.python-version'.
|
|
#
|
|
# When you run a Python command, pyenv will look for a `.python-version'
|
|
# file in the current directory and each parent directory. If no such
|
|
# file is found in the tree, pyenv will use the global Python version
|
|
# specified with `pyenv global'. A version specified with the
|
|
# `PYENV_VERSION' environment variable takes precedence over local
|
|
# and global versions.
|
|
#
|
|
# For backwards compatibility, pyenv will also read version
|
|
# specifications from `.pyenv-version' files, but a `.python-version'
|
|
# file in the same directory takes precedence.
|
|
#
|
|
# <version> should be a string matching a Python version known to pyenv.
|
|
# The special version string `system' will use your default system Python.
|
|
# Run `pyenv versions' for a list of available Python versions.
