What happens after pip installation crashes

This is not really a bug report but a request for information. I know only pure python packages can be pip installed, but sometimes it is a little hard to tell beforehand. As an example, I was trying `pip install img2pdf`, but img2pdf depends on pikepdf which in turn depends on qpqf. Because qpdf is not built on python, a-Shell crashed. After the crash, I just force quit a-Shell. When relaunched, the app was behaving normally. Neither img2pdf nor qpdf showed up in `pip list'. The only visible difference was a slight increase (0.04G) of a-Shell in the iPad Storage.

Question: can I just continue using a-Shell? When I was trying out a-Shell, I used to just reinstall the entire app, but it becomes more difficult as I accumulate more stuff over time.
