Installation issues

[xpal1]

I decided to download CakePHP for the first time but it didn't work out a bit. At first I downloaded it via Composer in the command line, but it still said that the plugins were not enabled, even though they were, I had created the project but I couldn't view it normally like in my browser on Localhost, so I decided to use Oven. With the help of Oven, I almost succeeded until the end of the installation "Error installing package cakephp/plugin-installer" was displayed and the continuation of the installation was not successful. I'm using CakePHP version 4.0.10 and PHP version 8.1.6, mbstring, openssl and intl extensions are up and running fine, Composer version is 2.4.3. I really don't know where the problem could be.

The text that was written after the failed installation ended:

If someone could advise me, I would be very happy, because I would like to start, try to create a project using this framework :)

Same here.

Oven installs an old CakePHP Version (4.0 instead of 4.4). Try to fix this by changing line 119:

$branches = ['4.4', '4.0.', '3.8.', '3.7.', '3.6.', '3.5.'];

You should now be able to select v4.4.7. I was able to install then. You may have to delete your session cookie to see the change.
