why i cant use gem install command (linux/ ruby / rails)

Question

hi all

I'm having problems when issuing 'gem' command

I have both rubygems1.8 and rubygems1.9 my rails version is rails-2.3.3 my ruby ruby 1.8.7 and i'm on linux

my problem is i cant issue 'gem install ' , instead i have to give 'gem1.8 install '

can anyone tell me why is that ??

thanks in advance

cheers sameera

Answer 1

Because you installed two different versions and they can't both be named "gem."

Answer 2

Create a symbolic link to gem1.8

ln /usr/bin/gem1.8 /usr/bin/gem
