🐉 See What’s Installed

>>> import mork
>>> venv = mork.VirtualEnv.from_project_path('/home/user/git/pipenv')
>>> dists = venv.get_distributions()
>>> [dist for dist in dists][:3]
[wheel 0.31.1 (/home/user/.virtualenvs/pipenv-MfOPs1lW/lib/python3.7/site-packages), Werkzeug 0.14.1 (/home/user/.virtualenvs/pipenv-MfOPs1lW/lib/python3.7/site-packages), vistir 0.1.4 (/home/user/.virtualenvs/pipenv-MfOPs1lW/lib/python3.7/site-packages)]

🐉 Install A Package

>>> from requirementslib.models.requirements import Requirement
>>> r = Requirement.from_line("requests")
>>> venv.install(r, editable=False)

🐉 Uninstall a Package

>>> pkg = "pytz"
>>> with venv.uninstall(pkg, auto_confirm=True) as uninstall:
        if uninstall.paths:
            cleaned = pkg
>>> print("Removed package: %s" % cleaned)

🐉 Display Information about Python

>>> venv.python
'/home/user/.virtualenvs/pipenv-MfOPs1lW/bin/python'
>>> venv.python_version
'3.7'

🐉 Run Commands Inside the Virtualenv

>>> cmd = venv.run("env")
>>> [line for line in cmd.out.splitlines() if line.startswith("VIRTUAL_ENV")]
['VIRTUAL_ENV=/user/hawk/.virtualenvs/pipenv-MfOPs1lW']
>>> cmd = venv.run_py(["import os; print(os.environ.get('VIRTUAL_ENV'))"])
Deactivating virtualenv...
>>> cmd.out
'/home/user/.virtualenvs/pipenv-MfOPs1lW\n'
>>> with venv.activated():
        print(os.environ["VIRTUAL_ENV"])
/home/hawk/.virtualenvs/pipenv-MfOPs1lW
