Hi,

I'm trying to install the exaworks package, which has py-cryptography as one of its dependencies, on a machine with a firewall that blocks almost all outbound access. I've been successful in installing everything on another machine, and I thought I would be able to create a mirror and copy it over to the the machine without internet access to make it work there. In fact the mirror does appear to function well overall, and all packages except py-cryptography do get installed. The problem is, it appears the installation process for py-cryptography runs commands to download data from https://crates.io/api/v1/crates/quote/1.0.21/download. That won't work on that machine. So, what do I do? The mirror doesn't appear to contain everything py-cryptography needs. Here's some output from the install log:

      ############################
      Python recognizes 'cryptography.hazmat.bindings._rust' as an importable package,
      but it is not listed in the `packages` configuration of setuptools.

      'cryptography.hazmat.bindings._rust' has been automatically added to the distribution only
      because it may contain data files, but this behavior is likely to change
      in future versions of setuptools (and therefore is considered deprecated).

      Please make sure that 'cryptography.hazmat.bindings._rust' is included as a package by using
      the `packages` configuration field or the proper discovery methods
      (for example by using `find_namespace_packages(...)`/`find_namespace:`
      instead of `find_packages(...)`/`find:`).

      You can read more about "package discovery" and "data files" on setuptools
      documentation page.

I am not sure why the installation of py-cryptography needs to download data during installation, but that makes the source mirror an unviable option. I was able to get it to work by creating a build cache instead. Copying that over to the system without open outbound access to the internet solved my problem. It also (of course) makes the install there a LOT faster, so was probably the best solution all along. I suppose the downside is that this won't work when the architecture of the machines is different so you'd need to create build caches for all architectures you need.
