We received a pre release of one of our dependencies from the vendor in a tar.gz file. How can I use this in my project?

Thanks - I think I got it. So that "file://path/to/tar/file" entry goes in pants.toml:

[python-repos]

indexes.add = ["<file://path/to/tar/file>"]

Then just a normal entry in requirements.txt that refers to the package in the tar.gz.

actually just the path to a directory, pip will figure out the file name based on the package name and the version.

Thanks for the help - It seems to be working now
