uv install -r … fails with comment in -e ./local_package # via other_package

[PeterW-LWL]

The Problem

Running uv pip install -r requirements.txt -v failes with error code 2 and the following output:

INFO Found a virtualenv through VIRTUAL_ENV at: [workspace]/.venv
DEBUG Cached interpreter info for Python 3.12.2, skipping probing: .venv/bin/python
DEBUG Using Python 3.12.2 environment at .venv/bin/python
DEBUG Trying to lock if free: .venv/.lock
DEBUG Using registry request timeout of 300s
DEBUG Building (editable) file://[workspace]/lwl_inclusive_plugins
DEBUG Solving with target Python version 3.12.2
DEBUG Adding direct dependency: setuptools>=40.8.0
DEBUG Building (editable) file://[workspace]/local_package_2%20%20%20%20%20%20#%20via%20local_package_1
error: Failed to build editables
  Caused by: Source distribution not found at: [workspace]/local_package_2

The requirements.txt looks like this:

# This file was autogenerated by uv via the following command:
#    uv pip compile --annotation-style=line --output-file=requirements.txt requirements.in
-e ./local_package_1
-e ./local_package_2      # via local_package_1

The possible solution

Removing the comment in the last line of the requirements.txt fixes the problem.

# This file was autogenerated by uv via the following command:
#    uv pip compile --annotation-style=line --output-file=requirements.txt requirements.in
-e ./local_package_1
-e ./local_package_2

The uv pip compile command will regenerate this comment (as there is a dependency from local_package_1 to local_package_2.

uv pip install -r … should ignore the comment not just for normal lines like

django==5.0.3             # via django-cms

but also for lines starting the -e
