Clarify README to indicate that default-gems file needs to be placed in $RBENV_ROOT

[jsallis]

The README states that the default-gems file needs to be located at ~/.rbenv/default-gems.

I've created a homebrew package for rbenv-default-gems (pull request here) and when installed via homebrew, the default-gems file has to be placed in $RBENV_ROOT which defaults to /usr/local/opt/rbenv instead of ~/.rbenv.

I'm not sure if $RBENV_ROOT is set when rbenv is installed manually without homebrew

Maybe the README could be clarified to indicate that the default-gems file location is potentially not ~/.rbenv though?

I was bitten by that problem: Homebrew/legacy-homebrew@b7f2f88#commitcomment-2576034

Homebrew does not set $RBENV_ROOT automatically (it's just mentioned in the caveats for rbenv). I'm suspecting rbenv-default-gems uses that environment variable, when the definitive information is given by rbenv root.

@cdlm Can you try and set RBENV_ROOT and confirm that rbenv-default-gems behaves correctly after that?

[jsallis]

As a note, here's my environment settings:

$ echo $RBENV_ROOT
/usr/local/opt/rbenv

$ rbenv root
/usr/local/opt/rbenv

[cdlm]

$ rbenv root
/Users/damien/.rbenv
$ echo $RBENV_ROOT
/Users/damien/.rbenv
$ cat $RBENV_ROOT/default-gems

I've tried putting debug statements in default-gems.bash and it looks like it's not even loaded when I rbenv install something… 😕
What did I miss here, is it not supposed to register itself into rbenv ?

[cdlm]

OK, I've removed ~/.rbenv entirely and changed my shell config to have $RBENV_ROOT point to homebrew, and created $RBENV_ROOT/default-gems. Seems to have fixed things.

What threw me off is the wording in brew info rbenv, which suggests setting $RBENV_ROOT is optional even if you intend to use rbenv plugins. Other plugins seemed to work so I supposed it was ok to leave it unset and use ~/.rbenv.

[MikeMcQuaid]

I should have fixed the wording now but if you have any more suggestions then let me know in the Homebrew issue/commit.

What’s the final verdict here please? When installed via/using homebrew should anyone avoid ~/.rbenv?

[MikeMcQuaid]

No, it's fine to use ~/.rbenv (and in fact I'm doing that now). You should set RBENV_ROOT either globally or just use ~/.rbenv; Homebrew is happy with either.

👍

[cdlm]

… and ~/.rbenv/default-gems works fine too

@cdlm I can’t agree on that...
