# Summary: Install a Python version using python-build
|
|
#
|
|
# Usage: pyenv install [-f] [-kvp] <version>
|
|
# pyenv install [-f] [-kvp] <definition-file>
|
|
# pyenv install -l|--list
|
|
# pyenv install --version
|
|
#
|
|
# -l/--list List all available versions
|
|
# -f/--force Install even if the version appears to be installed already
|
|
# -s/--skip-existing Skip if the version appears to be installed already
|
|
#
|
|
# python-build options:
|
|
#
|
|
# -k/--keep Keep source tree in $PYENV_BUILD_ROOT after installation
|
|
# (defaults to $PYENV_ROOT/sources)
|
|
# -p/--patch Apply a patch from stdin before building
|
|
# -v/--verbose Verbose mode: print compilation status to stdout
|
|
# --version Show version of python-build
|
|
# -g/--debug Build a debug version
|
|
#
|
|
# For detailed information on installing Python versions with
|
|
# python-build, including a list of environment variables for adjusting
|
