Composer error when installing drush in DDEV local dev env.

Adding OS and DDEV version in the Issue Summary, since I don't get this error, using Debian 12 and DDEV 1.23.4. So the major difference seems to be OS ...

What composer version was used when the error occurred?
The output of $ composer -v would be most welcome.

I can't reproduce this as written. Let's also have a look at the composer.json file because those errors don't make sense.

I don't see a connection with this issue and 🐛 [PP-1] Performance issues with path alias generated queries on PostgreSQL Postponed except that someone complained about this there so I am removing it, as I suppose whatever this is could happen any time under some circumstances.

I forgot to remove the link.

I updated the summary to include that this issue follows from the discussion thread on that documentation page, which would have been good to know up front. We really need to see the composer.json file now.

Just checking: is that the one that does, or does not work?

Thats the one that does not work.

That's the default composer.json in the repo.

Following https://www.drupal.org/community/contributor-guide/reference-information... → on a Mac I still cannot reproduce this. Every step runs perfectly and step 9, the workaround, is unnecessary. .ddev/config.yaml is as follows:

name: drupal-test
type: drupal
docroot: .
php_version: "8.3"
webserver_type: nginx-fpm
xdebug_enabled: false
additional_hostnames: []
additional_fqdns: []
database:
    type: mariadb
    version: "10.11"
use_dns_when_possible: true
composer_version: "2"
web_environment: []
corepack_enable: true

# Key features of DDEV's config.yaml:

# name: <projectname> # Name of the project, automatically provides
#   http://projectname.ddev.site and https://projectname.ddev.site

# type: <projecttype>  # backdrop, craftcms, django4, drupal, drupal6, drupal7, laravel, magento, magento2, php, python, shopware6, silverstripe, typo3, wordpress
# See https://ddev.readthedocs.io/en/stable/users/quickstart/ for more

I tested on an M1 architecture Mac. docker image ls shows v1.23.4 for the DDEV image versions.

I use a MacBook Air 2020 M1 Sonoma 14.6.1, I saw someone report this on slack on the #contrib channel and i was able to replicate it, the workaround was recommended by him too.

I believe this is happening on your end and is happening to some others. What we need is to understand why.

I doubt platform issues are very much involved here because this is something to do with Composer.

Run Composer in its most verbose mode when trying to install Drush. Post the output here.

For all I know this could be a regional, CDN issue.

Also let’s see composer show -a drupal/core. Add -vvv if it allows that.

here is the output

That is the output of which command? I asked for two. Please include the command with its output and surround them in <code> tags for readability here.

edited my comment above for readability hope that helps.

Here is the diff between my output (at left) and yours (at right) just after step 7 in the doc → .

The diff made me wonder if this was something to do with docker installation, then i looked into this in more detail - I was playing with rancher and docker desktop, i noticed the context for kubernetes in docker desktop was set as rancher, but rancher i had uninstall. This prompted me to uninstall docker desktop and install docker and colima. after trying this I was able to do the ddev composer require drush/drush.

I will reachout to the other user who faced this issue and check with him - but thanks for your help @cilefen. I will leave the issue open till then, but aim to close soon.

It seems the problem is related to incorrect docker installation.

Great that this got cleared up, thanks for helping out @cilefen, and thanks for updating the documentation @nidash.
