Sorry you're having trouble with this.

spaCy 2.2.2 is older than Python 3.9, so there are no wheels for that Python version. That means you have to build spaCy, and possibly many of its dependencies, from source. For that version, Python 3.8 had wheels, so 3.8 or a slightly older version should install more quickly.

If possible, you might also want to look at spaCy v3, which was released early last year.

Hm. I just noticed that while your terminal output above is for Python 3.9, you also list other versions. If you have a slow install on other versions (3.8, 3.7) it might be a different issue. I would recommend you upgrade pip (pip install -U pip), and if that doesn't work, then please provide verbose output and we can check it.
