Cannot use pip module.

Ive tried using the following example:
```js
import { pip } from "https://deno.land/x/python/ext/pip.ts";

const np = await pip.import("numpy");
const plt = await pip.import("matplotlib", "matplotlib.pyplot");

const xpoints = np.array([1, 8]);
const ypoints = np.array([3, 10]);

plt.plot(xpoints, ypoints);
plt.show();
```

and in the terminal i get:
```
(bunpytest) ➜ bunpytest deno run -A --unstable-ffi index.js
Installing numpy

sys.exit(_main())

```

Reproduziere das Beispiel in index.js mit `deno run -A --unstable-ffi` unter Verwendung des `pip`-Einstiegspunkts aus https://deno.land/x/python/ext/pip.ts. Verfolge den gemeldeten PythonError aus pip's `__main__.py`; die Aufgabe ist abgeschlossen, wenn das Beispiel numpy und matplotlib ohne den gezeigten Fehler importieren kann.
