Invoke rbenv alias <name> <version>
to make a symbolic link from <name>
to
<version>
in the rbenv versions directory, effectively creating an
alias. The cool part is that if you pass in a point release as the name, you
can give --auto
to link to the latest installed patch level. For example,
rbenv alias 1.8.7 --auto
will automatically create an alias from 1.8.7
to
1.8.7-p371
(or whatever the most recent version you have installed is).
Plus, if you're using ruby-build, rbenv install A.B.C-pXXX
automatically
invokes rbenv alias A.B.C --auto
, so you'll always have up to date aliases
for point releases.
Whether it's a good idea to use these aliases in a .ruby-version
file, I
cannot say. I created this plugin to find out. If your only concern is
having to reinstall gems every time you install a new patch release, check out
rbenv-communal-gems.
