Can you please link some help how to continue?

Start over and follow the installation documentation step by step.
You really only have to copy paste and adjust to your system.

If you keep on getting those errors please consider using the package installation which is even easier.

I got the same error message somehow. I double-checked the documentation found here Install from source — Zammad documentation and there is this paragraph:

# Install gems for zammad
$ su - zammad
$ bundle set config without "test development postgres"
$ bundle install

For me bundle set config... produces an error but bundle config set... seems to work. Typo or error in my setup?

Thx, Uli

BTW: I got the error message because I’ve set the environment variables in the wrong startup script (.bashrc vs .profile) and changed executing the commands from an interactive session to a non-interactive one

The documentation has been verified against all supported package installation systems. Not more not less.
If your system does not match those systems, it’s not verified to be working.

The documentation contains the correct commands. Shouldn’t make a difference ruby wise.

5

OK, thx. But why has the documentation been changed from “bundle set config …” to “bundle config set …”? To me, this looks like it has been wrong and is fixed now. But never mind.

6

Well sorry, the times I have every documentation page and issue in my head are over I’m afraid.

Documentation currently states bundle config set without "test development mysql" which should be considered the correct style as of now. Docs will of course change when needed. So having a look at this page should help when ever needed: Install from source — Zammad documentation
