Sed in place instead?

[raxod502]

Done.

[jonathanmorley]

Can we add some regression tests? (even just the examples you listed above)

[raxod502]

Do you happen to know why the existing test suite didn't find this issue already? I see that you are using asdf-vm/actions/plugin-test, but perhaps it just runs the command and does not check that the version is correct?

I'm having this issue as well - the default bundler with ruby ends up getting used. Using this branch fixes it. What would it take to move forward on this?

[raxod502]

Ah, CI is not passing yet! asdf-vm/asdf#1078 needs to be merged upstream :)
