Updated version of docker-compose no longer works

[NicoHaase]

Hi there,
as an no that experienced user of brew, I'm posting this here. If this is the wrong place, please help me to find the proper one :)

This morning, I've updated my packages using brew upgrade and a new version of docker-compose was installed:

==> Upgrading 1 outdated package:
docker-compose 1.27.4 -> 1.27.4_1
==> Upgrading docker-compose 1.27.4 -> 1.27.4_1

This fetched a lot of stuff, including Python 3.9. I've posted the full output at https://gist.github.com/NicoHaase/3f1f3c70832bb37273e3c90d5c987b89. Sadly, running docker-compose fails now :( The output:

Traceback (most recent call last): 
  File "/home/linuxbrew/.linuxbrew/bin/docker-compose", line 33, in <module> 
    sys.exit(load_entry_point('docker-compose==1.27.4', 'console_scripts', 'docker-compose')()) 
  File "/home/linuxbrew/.linuxbrew/bin/docker-compose", line 25, in importlib_load_entry_point 
    return next(matches).load()

    import dotenv 
ModuleNotFoundError: No module named 'dotenv' 

What can I do about this? Did I miss some upgrade steps, or is this a bug?

EDIT: For more clarity, I'm using brew on Ubuntu 20.04. If you need any more information, please don't hesitate to ask. Thanks for your great work, and for your help to spot the problem

@Homebrew/linux any ideas?

[zx8]

I'm having a similar issue on Linux. It seems to be related to the wrong Python executable being substituted into the first line of the binary:

#!/home/linuxbrew/.linuxbrew/opt/[email protected]/bin/python3.9

Rather than the formula-specific Python:

#!/home/linuxbrew/.linuxbrew/Cellar/docker-compose/1.27.4_1/libexec/bin/python3.9

So the dependencies aren't being found.

Yes, we're aware of this issue and are working it out. All formulae which use virtualenv_install_with_resources are likely affected on Linux. The relevant code is in language/python.rb and likely related to differing behavior of virtualenv 20 vs 16 on Linux. Any assistance would be appreciated.

[NicoHaase]

Thank you for your answer! I'm sorry that I'm not a Python expert, so I cannot help in fixing the problem. But if you need somebody to test, I'd be happy to help

Homebrew/brew#8880 has fixed this. You can update and try again. The bottle is fixed, if you build from source you need to apply Homebrew/brew#8880 first to make it work.

Thanks, this worked

Experiencing the same with

Homebrew 2.5.6
Homebrew/linuxbrew-core (git revision 086887; last commit 2020-10-16)
Homebrew/homebrew-cask (git revision 4859a; last commit 2020-10-16)

Homebrew/brew#8880 is included for this build, but docker-compose --version outputs

Any ideas? Already removed and cleaned everything, but the error still exists.

A brew link --overwrite docker-compose did the trick, even it was removed and cleaned before.
