Is there a way, to activate an extension in TYPO3 without using the extension manager in the backend?
I'm using TYPO3 7.6.4 in composer mode. If I install a new extension with composer, it is deactivated by default.
What am I missing?
Composer does not install the extension TYPO3 wise. It only downloads it to typo3conf/ext
. You can read more about it here if you are interested.
There is, however, an alternative to the extension manager for (un)installing extensions in TYPO3. You can run a CLI command to do so. Go to your web directory and run
./typo3/cli_dispatch.phpsh extbase extension:install <extension_key>
or for the "help page" of the command:
./typo3/cli_dispatch.phpsh extbase help extension:install
