UV exported requirements with editable can't be installed with `pip`

[ion-elgreco]

When exporting the UV lockfile into a requirements.txt with uv export > requirements.txt, will not allow you to install it with pip due to this error:

ERROR: The editable requirement file:///home/<redacted>/<redacted> (from -r requirements.txt (line 3)) cannot be installed when requiring hashes, because there is no single file to hash.

Minimal exported UV requirements.txt:

# This file was autogenerated by uv via the following command:
#    uv export
-e .
aiohappyeyeballs==2.4.0 \
    --hash=sha256:55a1714f084e63d49639800f95716da97a1f173d46a16dfcfda0016abb93b6b2 \

This is a pip limitation, that is tracked in pypa/pip#4995. There is a also a related issue for VCS URLs: pypa/pip#6469.

I think you should use --no-hashes here (uv export --no-hashes).
