Why does composer create-project for Drupal fail in WSL2?

I am a Drupal site builder experimenting with WSL2 and I am finding the routine creating a Drupal project with composer does not complete.

My PC has 16GB RAM and composer is allowed unlimited memory. To the best of my understanding I have Docker configured correctly for WSL2.

The create-project process starts normally but then stalls when installing drupal/core (9.0.2). This appears to be so whether downloading from source or from cache. After a considerable time the process will fail. The contents of the project folder are largely incomplete.

I first attempted this with a Drupal 9 recipe for DDEV, a container based local dev environment which includes composer.

Not wishing to point the finger at DDEV, I then installed composer via Homebrew in the Home directory of WSL2 and tried again, independently of DDEV or Docker. After running composer create-project drupal/recommended-project my_site_name_dir I find that composer fails in exactly the same way.

Composer output follows;

Solution

  • After reading some updated documentation I now understand the problem was that I was attempting to perform this operation under the Windows file system at .mnt/c/Users/Paul instead of the Linux location of /home/paul

    As well as completing without errors, performance is vastly improved.
