I came across this error when trying to install extensions and I would like to share it with the community to see if we can find a resolution. This is what I have done:
Problem 1
- Root composer.json requires typo3/testing-framework dev-main → satisfiable by typo3/testing-framework[dev-main].
- typo3/testing-framework dev-main requires typo3/cms-backend 13..@dev → found typo3/cms-backend[v13.0.0, …, v13.2.1] but these were not loaded, likely because it conflicts with another requirement.
You can also try re-running composer require with an explicit version constraint, for instance, composer require bk2k/bootstrap-package:* to see if any version is installable, or composer require bk2k/bootstrap-package:^2.1 if you know which version you need.
Installation failed, reverting ./composer.json to its original content.
The error message indicates a conflict in version requirements between the typo3/testing-framework and typo3/cms-backend packages in your composer.json file.
To resolve this, I have tried multiple approaches, including but not limited to:
- Removing the current lock file and attempting to update both dependencies:
composer update typo3/cms-backend typo3/testing-framework
- Using the flag
--with-all-dependenciesto solve dependency-related issues:
composer update --with-all-dependencies
However, the issue persists as there is a conflict between the typo3/testing-framework package, which requires typo3/cms-backend 13.*@dev, and the actual versions of typo3/cms-backend found in the installation.
The persistent conflict between typo3/testing-framework and typo3/cms-backend suggests an underlying compatibility issue between these modules and another module already installed in your system.
I am new to TYPO3 but I am willing to learn because I believe in the platform from what I’ve read about. Any help will be appreciated!
