rbenv

I want to use Rails with Ruby 2.1.0, but it's using Ruby 1.9.3 (the system's version). I'm using rbenv to manage my Ruby versions. My steps were something along the lines of: $ rbenv install 2.1.0 $ rbenv global 2.1.0 $ sudo gem install rails -v 4.0.2 $ rbenv rehash $ rbenv versions system * 2.1.0 (set by /home/dennis/.rbenv/version) $ ruby -v ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux] $ rails new app && cd app $ rails server Rails is using is Ruby 1.9.3 (x86_64-linux), according to localhost:3000/rails/info/properties . A log message from rails server gives: INFO ruby 1.9.3 (2012

I'm using rbenv on my Ubuntu 10.04 server and I already installed ImageMagick, but I can't get RMagick to install successfully. I get the following error message Can't install RMagick 2.13.1. Can't find MagickWand.h Any ideas? Thanks! You need to install the development headers for libmagickwand like so: apt-get install libmagickwand-dev 来源： https://stackoverflow.com/questions/9855818/cant-install-rmagick-with-rbenv

Trying to get a cloned Rails app running. When running bundle install I get this error: Using mini_portile (0.5.0) Installing nokogiri (1.6.0) Gem::InstallError: nokogiri requires Ruby version >= 1.9.2. An error occurred while installing nokogiri (1.6.0), and Bundler cannot continue. Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.

I moved from RVM to rbenv on my production server. I uninstalled rvm using "rvm implode" and installed rbenv, ruby 1.9.2 , rails, passenger and nginx-module. I have not modified my originlal nginx.conf apart from changing the passenger_root as follows: 1st Try: passenger_root /root/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/passenger-3.0.9; passenger_ruby /root/.rbenv/versions/1.9.2-p290/bin/ruby; 2nd Try: passenger_root /root/.rbenv/shims/passenger; passenger_ruby /root/.rbenv/shims/ruby; Now, when I try to run my application I see the following error in error.log: [error] 1291#0:

I'm new-ish to Ruby and Rails. I am looking for a purely objective list of features and advantages/disadvantages of each. In an effort to keep preference out of this, please refrain from answering unless you have used all 3 systems. There's three main options available today: rvm which is the most established, but also the most intrusive in terms of shell modifications. rbenv which is lower impact, and still works as well. chruby which purports to be even lighter than rbenv . Personally I prefer rbenv because it works well with Homebrew and doesn't mangle the shell environment as much, but

I installed Ruby 1.9.3-p286 with rbenv. Now, after installing a newer version (p327), obviously, it doesn't know anything about the GEMs installed with the previous version. Is it possible to copy Gems from that version to the newer one, so that it won't be needed to download them all again? Austin Ziegler I've been looking at this specifically from the perspective of upgrading and reinstalling without downloading. It's not trivial, and I recommend you do some cleanup of your gems to minimize the amount of processing/installation that needs to be done (e.g., I had five versions of ZenTest
