pip_parse is not installing flask, asking for the packages jinja2, itsdangerous etc. for any python package like requests or pandas same issue is there.

continuoulsy asking packages for flask, if you include them in requirements.txt, it is asking for some other package. i am using bazel 7.1.1

I have found that you need to use the pip_compile_requirements rule to create the requirements_lock.txt file. If you do so, all the packages that a module depends on will be added in that requirements_lock.txt file. I have made an example when I tried to get it working https://github.com/pat-jpnk/bazel_pip_example/tree/main

We also have a examples/bzlmod and exmples/pip_parse examples. Consider looking at them.
