These two PRs allowed pip-compile --generate-hashes to detect and warn when a file would be uninstallable for hashing reasons. Fortunately pip-compile has all of the information it needs at compile time to know that the file will be uninstallable and to make useful recommendations for what to do about it:
What are package managers?
Package managers help us install software libraries and keep them up to date. If I want to load a URL and print the contents, I can add a dependency on a package like requests …
Why is it not necessary to use version control links with --generate-hashes?

That seems like a bad security tradeoff for several reasons. I filed a bug with pip to open up discussion on the topic.

Distinguish Packages from Dependencies
Packages refer to those Python libraries that are required to run your application. Dependencies are libraries that the packages require to be able to run.
Dependency Resolution
Python dependency resolution refers to the ability for a package manager (like pip) to be able to not only pull in all the dependencies required by the packages in your project, but also be able to ensure they are all compatible with each other. Unfortunately, neither pip nor pip tools are able to accomplish this.
Virtual Environment Creation & Updating
As most Python software engineers know, the best practice is to install each of your projects in a virtual environment in order to isolate dependencies and prevent conflicts.
Multiple Python Environment Configurations
A separate configuration of the Python runtime environment is often required for each environment the application is to be developed, tested and run in.
Non-configured fileMatch
The pip-compile manager has an empty array for default fileMatch, meaning it won't match any files ever by default. You can "activate" the manager by specifying a fileMatch pattern such as:
