Vagrant can't be used with Ruby installed via asdf

[darwin67]

When trying to use vagrant command with a system having Ruby installed via asdf, the embeded ruby with Vagrant will get entangled with the user installed Ruby and fail.

Debug output

https://gist.github.com/darwin67/3311525d2af504751b54ce037c3272ef

Expected behavior

The desired behavior is Vagrant should just use the Ruby version that it comes with from installers and leave the user installed version alone.

Actual behavior

Vagrant embeded ruby calling user installed Ruby. Completely uninstalling Ruby from asdf seems to resolve the issue but that's not a real solution.

Reproduction information

Vagrant version

2.3.0

Host operating system

Arch Linux

Guest operating system

N/A

Steps to reproduce

1. Install vagrant via sudo pacman -S vagrant
2. Install Ruby via asdf asdf install ruby 2.7.0 and then set it as global asdf global ruby 2.7.0 (ruby version doesn't really matter, 3.x also have similar issues)
3. Run vagrant in the command line and the error should show up.

Vagrantfile

FYI, since Ruby 2.3 is end of life and uses an incompatible version of openssl iirc, I can't install 2.3.0 to try to match the embeded version for work around. Just doesn't work.

2.3.0 is the version of Vagrant, not the Ruby version.

That being said, I have the same issue, same error. In my case, Ruby is managed by rbenv.

Would you please provide a gist of the debug output from running the command (all output when the --debug flag is included).

Thanks!

In my case, Vagrant is called from test-kitchen (more precisely, its kitchen-vagrant plugin), and I don't think I can make it use the debug flag. Here's the output as is:

From this output, it's clear that Vagrant's gems in /opt/vagrant/embedded/gems get mixed up with my rbenv gems in /home/geewiz/.rbenv.

I think my issues are not caused by a bug in Vagrant. I just cloned and installed the repo, and it works on my Manjaro Linux. Based on this, it's more likely the most recent Arch Linux build that's broken.
