Unable to import ttkbootstrap

[jorgepal]

I am new to this, and I am trying to use ttkbootstrap. Using PyCharm on Linux, and I get the error "ModuleNotFoundError: No module named 'ttkbootstrap'" when trying to run one of the tests. The build did not produce any errors. I have this Python: Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux. I would appreciate any help.

Did you first install the package?
Please refer to the following documentation regarding installing the package.

Please first make sure that tkinter is installed by executing the following command.
python3 -m tkinter
If the above command throws module not found related error, please install tkinter via following command and try again.
sudo apt install python3-tk

Yes, tkinter is installed and if I run the command you sent I get a test GUI which works fine. All this outside PyCharm. If I debug the test function I tried, it goes beyond the import tkinter OK, so tkinter is found. What is not found is ttkbootstrap, and this is correct since I do not see any ttkbootstrat.py anywhere in my Linux disk, so obviously cannot be found...All this is very frustrating really

OK. Thank you for confirming that the tkinter is installed.
Then can you open a terminal and execute the following command.
If ttkbootstrap is installed successfully, you should see a ttkbootstrap related GUI Windows open.

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install ttkbootstrap
python3 -m ttkbootstrap

@jorgepal
Were you able to run the mentioned command successfully?

[jorgepal]

No, it does not work. I am giving up on this. Thanks anyway.
