Hi

Sorry if wrong forum but im a bit lost. I seem to have multiple ruby
installs and gem commands dont work how i expect.

ruby -v

ruby 1.9.3p374 (2013-01-15) [i686-linux]

/opt/ruby/bin/ruby -v

ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-linux]

/opt/ruby-enterprise-1.8.7-2012.01/bin/ruby -v

ruby 1.8.7 (2011-12-28 MBARI 8/0x8770 on patchlevel 357) [i686-linux],
MBARI 0x8770, Ruby Enterprise Edition 2012.01

grep ruby /etc/httpd/conf/httpd.conf

LoadModule passenger_module
/opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.11/ext/apache2/mod_passenger.so
PassengerRoot /opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.11
PassengerRuby /opt/ruby/bin/ruby

How do i uninstall the unused ones - i am assuming those are enterprise
and 1.9.3?

When i run gem commands, unless i use full path it doesnt work…

gem -v

/usr/bin/ruby: No such file or directory – ‘–prefix=/usr’ (LoadError)

/opt/ruby-enterprise-1.8.7-2012.01/bin/gem -v

1.8.15

/opt/ruby/bin/gem -v

/usr/bin/ruby: No such file or directory – ‘–prefix=/usr’ (LoadError)

So i guess that a path is wrong somewhere? How do rectify this?

Many thanks
JB

Forum is OK - I’m just not sure whether we can answer your questions.
:slight_smile:

You can likely uninstall 1.9.3 with your operating system’s package
manager - whatever that is. For the other ones, it depends whether
they were installed with rvm or compiled from source. Since there
seem to be dependencies to other installations (httpd) I suggest you
ask the person who installed them or who is responsible for the other
software.
