Unable to install c2pa on a MacOS

[benhylau]

I am trying to install this on a M1 Mac with Big Sur, but hitting this error:

❯❯❯ python3.9 -m pip install c2pa
DEPRECATION: Configuring installation scheme with distutils config files is deprecated and will no longer work in the near future. If you are using a Homebrew or Linuxbrew Python, please see discussion at https://github.com/Homebrew/homebrew-core/issues/76621

I initially suspected this is a problem with my local environment, but I have updated everything, and this seems to be the only package giving me this problem. Here's a successful installation of another python package:

❯❯❯ python3.9 -m pip install pillow

I understand the instructions are for Linux, but this part should be same across platforms. Has anyone tried this on a Mac, or this latest package on Linux?

This part shouldn't matter, but I also have done a brew install swig. Where is swig needed anyways?

Thanks for the help!

Hello Ben,

I'm using intel Mac with Big Sur 11.5.2, and I have encountered the same problem before.
Don't remember all the detail, but I think it's a problem with py3exiv2 installation.

Here's the link that helped me resolve the problem. Hope that it can help!

Thanks @vincent10400094 this is helpful, at least I know what direction to look now. I followed the linked instructions:

1. Download the py3exiv2 package from here
2. Run brew install boost-python3 gexiv2 pygobject3
3. pip3.9 install py3exiv2-0.9.3.tar.gz <- this fails

I am still getting the error even if I use the local file:

❯❯❯ pip3.9 install py3exiv2-0.9.3.tar.gz

I tried several earlier releases but same problem. Do you remember if you had to do anything else?

I also notices this dependency doesn't officially support MacOS, so perhaps I am better off using a Linux machine.
