I'm trying a quick eval of Meltano and trying to install the mysql extractor with

meltano add extractor tap-mysql

ran into this error (all other steps seemed to have worked):

Copy code

Building wheel for pendulum (pyproject.toml): started
  error: subprocess-exited-with-error
  
  × Building wheel for pendulum (pyproject.toml) did not run successfully.
  │ exit code: 1
  ╰─> See above for output.

This is on M2 Pro MacOS 14.7 with pyenv running 3.12.6 right after installing meltano with

Copy code

pipx install "meltano"
  installed package meltano 3.6.0, installed using Python 3.13.1
  These apps are now globally available
    - meltano

Any suggestions appreciated

Hy @Kurt Snyder! Can you try again? I just merged a PR that removed a few unneeded dependencies from tap-mysql.

Thanks, installing the same failed in the same way but when I tried it with

--variant meltanolabs

(not in the onboarding instructions) it worked (after having failed yesterday too), thanks

Would you know why this extractor would give me ssh config errors when ssh_tunnel.enable is set to false?

Copy code

ssh_tunnel.enable [env: TAP_MYSQL_SSH_TUNNEL_ENABLE] current value: False (default)
	SSH Tunnel Enable: Enable an ssh tunnel (also known as bastion host), see the other ssh_tunnel.* properties for more details
...

Note that explicitly setting ssh_tunnel to false via the interactive config (versus relying on its default value) did not fix the problem
