问题 Trying to get a gem working so, following a SO suggestion, I deleted older versions of ruby I had as follows: $ which -a ruby /Users/snowcrash/.rvm/rubies/ruby-1.9.2-p318/bin/ruby /Users/snowcrash/.rvm/bin/ruby $ rm /Users/snowcrash/.rvm/bin/ruby However, a couple of hours later I tried which -a ruby again and this file had returned: /Users/snowcrash/.rvm/bin/ruby Any suggestions how that happened?

问题 I installed Ruby 1.9.2. I used rvm use 1.9.2 and then when I type ruby -v it says 1.9.2. Then when I quit terminal and reopen it, it says 1.8.7 again. What am I doing wrong? 回答1: Your default ruby is most likely not set to ruby 1.9.2. Try: rvm --default use 1.9.2 Also if you want to see all ruby versions installed, you can run 'rvm list'. The default ruby is prefixed with a => symbol, as shown below. $ rvm list rvm rubies ruby-1.9.1-p243 [ x86_64 ] => ruby-1.9.2-p136 [ x86_64 ] ruby-1.9.2

问题 I have been trying to install RVM and Ruby 2.1.1 onto my new Mac (OS 10.9.2), and everything seems to be going well until I try to install any version of Ruby. My input $ rvm reinstall 2.1 So far so good... ruby-2.1.1 - #removing rubies/ruby-2.1.1.. Searching for binary rubies, this might take some time.

问题 Is it possible to update the list of known rubies (what you get with rvm list known ) without upgrading the entirety of rvm? 回答1: No it is not, some of the version changes require changes in code, you should be good with sticking to stable to keep more stability (if that is your concern): rvm get stable you should be good with sticking to master (as it's stable) to get latest versions: rvm get master 回答2: mpapis answer and opinion is 100% correct. The settings I had in my laptop is below. Add

问题 I read "Relationships between Rubygems, Bundler, and RVM" before asking it again. Well, there are many questions like this, but people who answered say they work with Rubygems, RVM and Bundler, and they have not explained how each of these work in isolation. I am really confused with how the three work in isolation when we are installing gems. Please do not tell me how you work, which will help me, but I won't learn what is happening when we play with them. My confusion can be broken down

问题 I'm running Ubuntu 12.04 LTS, and installed Ruby via RVM. The problem is, when I type ruby -v into the terminal, it says that my Ruby version is 1.8.7 , and using the shotgun gem for Sinatra also says that I'm running Ruby 1.8.7 .

I installed Ruby 2.0.0 via RVM and it is the only version I had installed on my machine. Now when I tried to install Rails 4 but
