validate_email dependency

[tumbl3w33d]

I've been using envelope for a few years and last night my CI build broke due to the dependency validate_email gone missing:

  File "/home/jenkins/agent/workspace/myproject/app.py", line 4, in <module>
    from envelope import Envelope
  File "/usr/local/lib/python/envelope/__init__.py", line 1, in <module>
    from .envelope import Envelope
  File "/usr/local/lib/python/envelope/envelope.py", line 29, in <module>
    from .address import Address
  File "/usr/local/lib/python/envelope/address.py", line 8, in <module>
    from validate_email import validate_email  # noqa, #17 E402, the package name is py3-validate-email
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'validate_email'

I went to pypi to figure out the status of that module and noticed there are a few candidates with very different age. Could you elaborate what changed recently that possibly caused this and which module I should install, if I am to fix this on my own?

Strange it happened! The module the envelope uses is https://pypi.org/project/py3-validate-email/ . As I read there, the author decided to leave pypi but the last version seems up and working.

The package name is correctly stated in https://github.com/CZ-NIC/envelope/blob/master/requirements.txt which means py3-validate-email should have been correctly installed alongside envelope.

Alright, thanks for confirming the package name. When I explicitly add that to my requirements.txt in addition to envelope, it works as expected. Might be a bug or change of behavior in the alpine toolchain (which is not exactly python-friendly). I'm building all of this in a multistage dockerfile and there were no errors whatsoever, but it just wouldn't install this dependency.

Adding that explicit dependency is a workaround that I can live with. Thank you for your feedback!

Thanks for having investigated! If that will raise the issue for other people, I'll try to tackle it more.

It was some strange things...

I had different dependency package versions specified for different Python3.8; some newer releases were declined by Pypi due to licensing (it seems) and hence, when build from Pypi, dependency missed. No, it should work again.
