As I have not yet tried to play around with virtual environments, I may be about to do more harm than help, but I will plow ahead anyway! ~(:>)) My primitive understanding of installing Python versions that are different from the system Python version into a virtual environment, is that you have to install all dependencies you need from within that virtual environment you created. If I am correct about this then your error messages suggest you need to install the tkinter stuff from within that virtual environment using that virtual environment's pip. Hopefully I am too far off from the truth here, but in any event, I hope this helps you in your problem! -- boB _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
