Should I uninstall rbenv before installing asdf?

Question

I wish to install asdf in order to provide for multiple language environments (ruby/python/postgres..) for macOS development. Previously I have used rbenv to install ruby, and use several ruby gems, including for Cocoapods. Should I first uninstall rbenv?

Is it also necessary to uninstall ruby version(s) installed with rbenv first, as suggested by a previous SO question?

I have reviewed previous FAQ but advice seems dated and relates to previous versions of shell and version managers.

Answer 1

I would recommend keeping rbenv installed, but forgoing the initialization of rbenv.

For example, if you have something like the following in your .bashrc or .zshrc:

eval "$(~/.rbenv/bin/rbenv init - bash)"

Comment that out.

Once you do that, then you can install asdf, then initialize it (like it says to do for your system/shell). We comment out the rbenv stuff so only the asdf things are in the path, and there is no conflict. But, we don't uninstall rbenv in case you want to go back to using it.
