# Run pip outside of environment

At a glance:

```console

$ virtualenv --no-pip myenv  # Create environment without pip.

$ source myenv/bin/activate  # Activate environment.

$ pip --version      # pip is not available.

bash: pip: command not found

$ ouo install six    # But we can still do this.

Collecting six

  Using cached six-1.15.0-py2.py3-none-any.whl (10 kB)

Installing collected packages: six

Successfully installed six-1.15.0

$ python -c 'import six; print(six.__file__)'

.../myenv/lib/python3.9/site-packages/six.py

```

## How?

`ouo` downloads pip wheels into the user's data dirctory. When executed, it

executes pip with something like

```

/path/to/python /path/to/pip-20.3.3-py2.py3-none-any.whl/pip

```

where the path of the Python interpreter is detected with the `VIRTUAL_ENV`

environment variable. The interpreter would then perform a zip import to

execute the pip module inside the wheel.

## What's up with the name?

I often mistype `pip` on one of my keyboards. `ouo` is `pip` shifted one

position to the left on QWERTY.

## Future Works

* `setuptools` and `wheel` are still needed to build legacy (non-PEP-517)

  source distributions. This makes `python -m venv --no-pip` unrealistic.

* Invocation is slow. This has two causes: `ouo` needs to iterate through

  the wheel directory to find a suitable pip version for the current Python

  version. Also, zip imports are very slow.
