I have just installed TYPO3 11.1 in DDEV on my Mac.

ddev config --composer-version "2" --docroot "public" --php-version "7.4" --project-name "typo3111" --project-type "typo3" --timezone "Europe/Berlin" --create-docroot

ddev start

ddev composer create "typo3/cms-base-distribution:^11.1" . --prefer-dist

Install Wizard Step 1-4 no problem.

On last Wizard I have chosen "Take me straight to the backend" -> "Open the TYPO3 backend", but the green button does not work.

May be there is a Doctrine version miss-match...



Updated by Stefan Froemken 7 months ago

TYPO3 installs Doctrine 2.13:

➜  typo3_111 ddev composer show doctrine/dbal    
name     : doctrine/dbal
descrip. : Powerful PHP database abstraction layer (DBAL) with many features for database schema introspection and management.
keywords : abstraction, database, db2, dbal, mariadb, mssql, mysql, oci8, oracle, pdo, pgsql, postgresql, queryobject, sasql, sql, sqlanywhere, sqlite, sqlserver, sqlsrv
versions : * 2.13.0

This matches issue ticket on GitHub:

Version of doctrine/dbal 2.13 was released just 3 days ago:

Don't know how we should solve that. Prevent installing 2.13 or solve the problem in Queries of TYPO3 core?

Maybe. The related patch was merged for the unreleased version 11.2 (master) and 10.4. But I have the issue in current TYPO3 11.1.1.

Can you check the latest dev-master (upcoming 11.3) - we've integrated a few Doctrine-related fixes there due to their new version.

IMO this problem was solved with 2.13.2 or 2.13.3. Currently I can not reproduce it anymore.
