Minipip currently has some issues with installing particular dependencies for some of the older libraries. The devs opened up an issue on it earlier in the year, but it seems that there may be some cases that haven’t been caught yet:
The quickest fix is to check the dependencies for the library that you’re using, and make sure that Thonny (or your chosen IDE) is able to find the libraries from your script (for example by downloading them manually into your lib folder as aivarannamaa describes in the GitHub issue I linked above rather than trying to use minipip as a package manager in this case)
Please let us know how you go with it. It’d be quite useful to know which resources to direct people to in future if they run into the same issue. All the best with your project! We’ll be here if you have any other questions.
