For the future, please pick a package manager that can give you a lock file alongside your code, so that you have a definitive record of the dependencies.

Even if you have all versions as of the time of the last modification to the code, you don't know if the dependency resolution happened at that point in time, or if the environment was set up years prior and never updated.

Nevertheless, this is what you are looking for: https://pypi.org/project/pypi-timemachine/
