Question

I installed rvm 1.9.3 and now whenever I switch to a directory containing a .rvmrc, I get a perl error message:

~/example$ cd .. && cd example

perl version 5.12.3 can't run /usr/bin/shasum.  Try the alternative(s):

/usr/bin/shasum5.10.0 (uses perl 5.10.0)

Run "man perl" for more information about multiple version support in
Mac OS X.

Answer 1

You may try this dirty approach. This approach will skip those check and directly use shasum in your binary directory

$ cd /usr/bin
$ ls shasum*
  shasum shasum5.10.0
$ mv /usr/bin/shasum /usr/bin/your_backup_shasum
$ ln -s shasum5.10.0 shasum
