--src <dir> Directory to check out editable projects into.
The default in a virtualenv is "<venv
path>/src". The default for global installs is
"<current dir>/src".
-U, --upgrade Upgrade all specified packages to the newest
available version. The handling of dependencies
depends on the upgrade-strategy used.
--upgrade-strategy <upgrade_strategy>
Determines how dependency upgrading should be
handled. "eager" - dependencies are upgraded
regardless of whether the currently installed
version satisfies the requirements of the
upgraded package(s). "only-if-needed" - are
upgraded only when they do not satisfy the
requirements of the upgraded package(s).
--force-reinstall When upgrading, reinstall all packages even if
they are already up-to-date.
-I, --ignore-installed Ignore the installed packages (reinstalling
instead).
--ignore-requires-python Ignore the Requires-Python information.
--no-deps Don't install package dependencies.

--install-option <options> Extra arguments to be supplied to the setup.py

absolute path.

--user Install to the Python user install directory for
your platform. Typically ~/.local/, or
%APPDATA%\Python on Windows. (See the Python
documentation for site.USER_BASE for full
details.)
--egg Install packages as eggs, not 'flat', like pip
normally does. This option is not about
installing *from* eggs. (WARNING: Because this
option overrides pip's normal install logic,
requirements files may not behave as expected.)
--root <dir> Install everything relative to this alternate
root directory.
--prefix <dir> Installation prefix where lib, bin and other
top-level folders are placed

-d, --dest <dir> Download packages into <dir>.
--platform <platform> Only download wheels compatible with <platform>.
Defaults to the platform of the running system.
--python-version <python_version>
Only download wheels compatible with Python
interpreter version <version>. If not specified,
then the current system interpreter minor
version is used. A major version (e.g. '2') can
be specified to match all minor revs of that
major version. A minor version (e.g. '34') can
also be specified.
--implementation <implementation>
Only download wheels compatible with Python
implementation <implementation>, e.g. 'pp',
'jy', 'cp', or 'ip'. If not specified, then the
current interpreter implementation is used. Use
'py' to force implementation-agnostic wheels.
--abi <abi> Only download wheels compatible with Python abi
<abi>, e.g. 'pypy_41'. If not specified, then
the current interpreter abi tag is used.
Generally you will need to specify
