Can't install bundler

I did rbenv install 2.4.3. I got no errors and I see that's it's there:

> cd ~/.rbenv/versions/
> ls -1
2.4.3

But I can't seem to access it:

I guess this is the problem:

> gem env home
/var/lib/gems/2.3.0

But I'm not sure how to fix it.

@gdonald Did you invoke rbenv shell 2.4.3 or rbenv global 2.4.3 ?

[sptndc]

Oh yes I forgot. To work with gems, you must invoke rbenv shell 2.4.3 or rbenv global 2.4.3 😅
