Mislav Marohnić 959968c46d Support GEM_HOME, add limited support for user-installed gems (#1436) ... The rehash process will now discover executables in additional locations: - `~/.gem/ruby/<version>/bin/*` - `$GEM_HOME/bin` The `rbenv which` (and thus `rbenv exec`) command will also search these locations when looking up a command. This enables shims to dispatch calls to executables added by `gem install --user-install`. Note that this support is limited: - It will only work with C Ruby, as it's difficult to guess the `~/.gem/<engine>/<version>` directory for other Rubies without actually loading Ruby; - It will only work for RBENV_VERSION values in the format `X.Y.Z` and not "system".		2022-09-26 02:57:15 +02:00
