Composer Packages problem on fresh 27.1 installation
Hello,
If you install Tiki 27.1 from a package, you don't need to install composer.
The package should be self-sufficient.

If you install Tiki 27.1 from CSV you need to run first sh setup.sh from your shell.
I wrote an article to install Tiki from Git. May be the Tiki install part will help you.
