The install command is the preferred way to globally install apps
from python packages on your system. It creates an isolated virtual
environment for the package, then ensures the package's apps are
accessible on your $PATH. The package's manual pages installed in
share/man/man[1-9] can be viewed with man on an operating system where
it is available and the path in the environment variable `PIPX_MAN_DIR`
(default: {constants.DEFAULT_PIPX_MAN_DIR}) is in the man search path
($MANPATH).
The result: apps you can run from anywhere, located in packages
you can cleanly upgrade or uninstall. Guaranteed to not have
dependency version conflicts or interfere with your OS's python
packages. 'sudo' is not required to do this.
pipx install PACKAGE_NAME ...
pipx install --python PYTHON PACKAGE_NAME
pipx install VCS_URL
pipx install ./LOCAL_PATH
pipx install ZIP_FILE
pipx install TAR_GZ_FILE
The PACKAGE_SPEC argument is passed directly to `pip install`.
The default virtual environment location is {constants.DEFAULT_PIPX_HOME}
and can be overridden by setting the environment variable `PIPX_HOME`
(Virtual Environments will be installed to `$PIPX_HOME/venvs`).
The default app location is {constants.DEFAULT_PIPX_BIN_DIR} and can be
overridden by setting the environment variable `PIPX_BIN_DIR`.
The default manual pages location is {constants.DEFAULT_PIPX_MAN_DIR} and
can be overridden by setting the environment variable `PIPX_MAN_DIR`.
The default python executable used to install a package is
{DOC_DEFAULT_PYTHON} and can be overridden
by setting the environment variable `PIPX_DEFAULT_PYTHON`.
