i tried to install the introduction package in a fresh installation of TYPO3 10.
- composer create-project typo3/cms-base-distribution => OK.
- Admin Tool till the end => OK.
- Login in the empty Backend => OK, all looks great.
- composer require typo3/cms-introduction
- ./vendor/bin/typo3 extension:activate bootstrap_package => Message OK
- ./vendor/bin/typo3 extension:activate introduction => no message
=> no page tree in the backend.
All extensions are installed but the import script of the introduction package did not run. I tried to deinstall the introduction package in the extension manager and reinstall it but the result is a grey screen in the extension manager.
Seems impossible to install the introduction package with composer. Any ideas? Thanks!
