# Summary: Set or show the global Python version(s)
|
|
#
|
|
# Usage: pyenv global <version> <version2> <..>
|
|
#
|
|
# Sets the global Python version(s). You can override the global version at
|
|
# any time by setting a directory-specific version with `pyenv local'
|
|
# or by setting the `PYENV_VERSION' environment variable.
|
|
#
|
|
# <version> can be specified multiple times and should be a version
|
|
# tag known to pyenv. The special version string `system' will use
|
|
# your default system Python. Run `pyenv versions' for a list of
|
|
# available Python versions.
|
|
#
|
|
# Example: To enable the python2.7 and python3.7 shims to find their
|
|
# respective executables you could set both versions with:
|
|
#
|
|
# 'pyenv global 3.7.0 2.7.15'
|
|
#
|
|
|
|
|
|
