rbenv

I tried to get rvm uninstalled in order to use rbenv on my Mac. Everything works fine until ruby comes into play.. when using rbenv install 1.9.3-p194 it compiles it correctly, but after that I'd like to install bundler.. this produces the following error computer:~ computer$ gem install bundler /Users/computer/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/psych.rb:203:in `parse': (<unknown>): mapping values are not allowed in this context at line 1 column 34 (Psych::SyntaxError) from /Users/computer/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/psych.rb:203:in `parse_stream' from /Users/computer/

In my Gemfile I specified ruby version 2.0.0: ruby '2.0.0' But my console tells me I have 2.1.0dev: $ ruby -v ruby 2.1.0dev (2013-09-16 trunk 42951) [x86_64-darwin12.4.0] I am using rbenv and it tells my I don't have 2.1.0 installed, $ rbenv versions system * 2.0.0-dev Bundle update or bundle install says: "Your Ruby version is 2.1.0, but your Gemfile specified 2.0.0" but using 'rbenv local 2.0.0-dev' leaves me with ruby 2.1.0dev again. Furthermore: $ rbenv global 2.0.0-dev $ cat ~/.bash_profile: export PATH="$HOME/.rbenv/bin:$PATH" if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

I seem to be constantly having problems with getting the gems in the right place (and not needing to use sudo when installing them.) To address the sudo issue, I installed rbenv and then use that to install ruby 2.1.0 so that I had a separate one from Mac OSX system. Then I installed bundler. But when I install gems from a Gemfile with bundler, I cannot find them. Between all the steps I have taken, such as adding lines to my .bash_profile and so forth, I have the following, but really just want a clear, straightforward way to manage gems and their local execution: gem env : Edit: I removed

Any commands that use sudo don't seem to work with RBenv. I'm trying to install ActiveRecord and it says I don't have write permission, so when I try this: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/local/rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1 directory. It says: sudo: gem: command not found How can I get around this? The idea behind tools like rbenv and RVM is that you don't need to use sudo , because your entire Ruby environment exists inside your own workspace as a sandbox. RVM allows multi-user configurations though it

I install ruby via rbenv-installer . When I use irb console, I can use history by pressing up and down on keyboard. And when I exited from console and start it again, I can't use prewious history. When I press up-arrow-button, nothing was happened. When I used rvm this option was working. How can I switch on it in rbenv? arturtr I found this way for solving my problem. In file ~/.irbrc write: require 'irb/ext/save-history' #History configuration IRB.conf[:SAVE_HISTORY] = 100 IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history" Found in this question: irb history not working Create ~/

I use plain Vim with ruby support on Lion (installed by gist ). I am using ruby with rbenv so my path looks like /users/me/.rbenv/shims:..... From within vim the path is :!echo $PATH > usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Users/fb/.rbenv/shims:.... Even I can create and modify an environment variable: :let $PATH = "/bar:/foo" :!echo $PATH > /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/foo:/bar paths remains starting with /usr/bin. So how can I access my ruby 1.9.3 in ~/.rbenv/shims instead the system ruby in /usr/bin ? This is a known problem introduced by

TL;DR Don't bother with gemsets; multiple versions of a gem may be installed concurrently. When necessary, specify which version to execute using $ gem-based-binary _version_ args notation. Use bundle exec when you have a Gemfile specifying the version. gem install rails -v 3.2.13 rails _3.2.13_ new Project2 cd Project2 bundle exec rails server UPDATE: 2015-06-04 I wrote this question three years ago. Partly, it was based on a false assumption, and partly the situation has changed since then. With appreciation to @indirect for his original answer, I want to call attention to @kelvin's newer
