Bins are not found after installing another version
I had installed 1.9.3-p374 and communized all versions. Then, after a while, I installed 1.9.3-p448. RCG said it had done its stuff. Okay.
RBEnv stopped finding the bins. I looked at the other issues (#3, #4), but I'm not sure this is exactly the same thing.

rbenv rehashdoesn't change anything -
--env-shebangis there
Here's a bit of debugging around.

I think the problem here is that rbenv-communal-gems handles sharing the gems/ directory between ruby versions, but doesn't handle bin/ dirs.
For instance:
# Install a gem
$ rbenv shell 2.1.0-preview1
$ gem install haml
# Result: you get ~/.rbenv/versions/2.1.0-preview1/bin/haml
# Check the gem in another version
$ rbenv shell 2.1.0
$ ruby -rhaml -e "puts 'haml loaded ok'" # okay
$ haml
# command not found: haml
# ~/.rbenv/versions/2.1.0/bin/haml does *not* exist
@rstacruz Thanks, your script works great! Had the same problem, installed a new Ruby version and all bins stopped working. Reinstalling the gems works, or running your script. @tpope Any plans to address this problem?
I only recently managed to reproduce this myself, and haven't had time to dig in. Something like that script in an after install hook sounds promising. Though implementing it in Ruby is just begging for trouble.
Can a symlink be created from .rbenv/versions/1.9.3-p194/bin to .rbenv/gems/1.9./bin ?
The symlink solution seems to work, but I used copy instead.
cp ~/.rbenv/versions/2.1.1/bin/rspec ~/.rbenv/gems/2.1.0/bin
A pure symlink won't work because in addition to the gem executables there are also things like ruby, which cannot be shared.
Any chance we could get something like @rstacruz's gist merged?
I took a stab at it, though it's a bit of a mess: https://gist.github.com/ab/b34fd3dfc7e185cd6e4c
I wasn't sure what to do with files in bin/ that have a shebang like #! $HOME/.rbenv/versions/2.1.6/bin/ruby, but copying them didn't seem like a good idea. There are also a handful of files that have a $!/bin/sh, which was a surprise.
Isn't that doing a lot more than the aforementioned gist? Not saying it's wrong, but if it's right then this problem is even more complicated than I realized.
Had to reinstall ruby 2.3.0 due to Sierra update. rbenv rehash does nothing to restore the bin stubs. Anything I can do to provide debug infos?
