Pip freeze generating '@ file:///' on conda environment

Question

First time this is happening to me, and I have no idea why pip is outputting the requirements in such strange form. I'm using a conda environment. Output example from pip freeze:

aioredis @ file:///home/conda/feedstock_root/build_artifacts/aioredis_1591809643295/work
amqp @ file:///home/conda/feedstock_root/build_artifacts/amqp_1591005859311/work
asgiref==3.2.7
async-timeout==3.0.1
attrs==19.3.0

Why aren't aioredis and amqp listed with their respective version just like the other requirements?

@phd I saw this, but it doesn't solve my problem, as I need to pass the requirements to a different machine. How can I force it to have the version? — Filipe Aleixo, Jul 13 '20 at 08:41

This solves it:

pip list --format=freeze > requirements.txt

This is universal: it prints also packages installed with conda and by pip from both PyPI and Github. – mirekphd Aug 26 '20 at 10:08

This works, but can you explain why the other doesn't? – j7skov Jul 20 '22 at 16:27

This works as long as there is no [pip package installed from a VCS](https://stackoverflow.com/a/35998253/1256347). For those packages the `pip freeze` command does show the correct output. Do you know how to combine the best of `--format freeze` and `pip freeze`? – Saaru Lindestøkke May 01 '23 at 09:42
