i am new to Mac and Ruby on Rails. so, please do understand me if i am posting a dumb question. but, i have been struggling with this problem for a few days with no progress, so i really need some help.
i installed ruby 1.9.2 with RVM. but, when i type “ruby -v” command after installation, it says that the ruby version i have is 1.8.7. so, i have tried “rvm use 1.9.2” command, but it still says my ruby version is 1.8.7. i even re-installed ruby 1.9.2 using RVM a few more time, but no luck. when i typed “rvm list”, it says ruby-1.9.2-p290. does that mean my rvm did install ruby 1.9.2, but for some reason, i cannot even get my RVM switch to ruby 1.9.2 from ruby 1.8.7?
what can i do to use ruby 1.9.2??
[added on Aug. 15th] By the way, I just type “rvm info”, and it says “ruby-1.9.2-p290” and then all the other stuff explaning. Does that mean that my rvm already has switched ruby to 1.9.2??? But, then, why “ruby -v” keeps saying “”ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]”???
I am writing an answer to my own question for anyone with the same problem that I’ve suffered!
The problem was with “rvm”!
I updated rvm instead of removing it (in some cases, it would be a good idea to completely remove rvm from your system, and re-install it). I followed rvm instructions: http://beginrescueend.com/rvm/install After updating rvm, I was able to install Ruby 1.9.2(!!), and the problem with
“rake” command was gone!!!
I should have suspected rvm sooner, then I wouldn’t have wasted one week!
PS Try avoid using sudo when it is not necessary when installing. Someone mentioned that he/she used “sudo” to install when he/she didn’t have to, and it just created the same problem as I was having!
