rvm

问题 I'm using Postgres.app on OS X (10.8.3). I have modified my PATH so that the bin folder for the app is before all others. Rammy:~ phrogz$ which pg_config /Applications/Postgres.app/Contents/MacOS/bin/pg_config I have rvm installed and can install the pg gem without error, but when I go to require it I get an error: Rammy:~ phrogz$ gem -v 1.8.25 Rammy:~ phrogz$ gem install pg Fetching: pg-0.15.1.gem (100%) Building native extensions. This could take a while... Successfully installed pg-0.15.1

问题 Background: I'm a designer that works well with HTML, CSS, and JS. But when it comes to setting up my environment is where I fall short. I recently purchased a home computer. I want to set up Middleman to use in a project. I already installed rvm and all its requirements. I am on ruby-2.0.0-p0, which from what I understand is the latest stable release. When I attempt to install Middleman, or any other gem for that matter, nothing happens. The cursor just moves to the next line. Some guidance,

问题 I used rvm to install ruby 1.9.3. even though it was successfully installed, it complained about libyaml. and now every time i wanna install a gem (say rails) this warning shows up: It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. I use Mac os X 10.7 (Lion). 回答1: In my case rvm pkg install libyaml and rvm reinstall ruby-1.9.3-p125 solved the problem. For people using Ubuntu, make sure that libtool is

问题 Now I must admit that I'm stumbling around in the dark a little bit as far as this deployment lark is concerned. I'll try and explain the situation best I can; I have set up a test deployment server and am trying to deploy my app to it with capistrano, however, I am encountering some difficulties surrounding my gems and their dependencies, as the error below shoes. [mike-test] executing command [mike-test] rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '1.9.3' -c 'cd /home/deploy/myapp

问题 I am using Ubuntu 12.04 LTS x86_64 Minimal and I have installed Ruby and RVM according to these instructions. Ruby installs fine, and RVM installs fine and works perfectly. I have visited just about every SO question I can find, and article on this issue and nothing has worked. Rails still won't install, and I am unable to do anything to get it to work thus far. gem install rails -v 4.0.0 returns either 'success' (it returns nothing, and rails remains unusable) or fails giving: [ tsujp ~ 437

问题 I had to downgrade Rails and now the gems, the versions, and everything, are completely messed up and I feel like jumping from my window. I just want to destroy everything related with RVM, Ruby and gems to make sure I make a 100% clean reinstallation. How can I do that? 回答1: Linux and installed as regular user ? Than all you need to do is: rm -Rf ./.rvm rm -Rf ./.gem rm -f ./.gemrc You can also check ~/.bashrc and ~/.bash_profile files for lines like this: PATH=$PATH:$HOME/.rvm/bin # Add RVM

问题 I'm trying to install ruby 1.8.7 Searching for binary rubies, this might take some time. No binary rubies available for: ubuntu/12.04/x86_64/ruby-1.8.7-p371. Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

问题 Eventhough I have Ruby 1.9.3 installed via RVM, every time I open a new Terminal and run "ruby -v" I get: ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin11.0] "rvm list" shows: rvm rubies ruby-1.9.3-p362 [ x86_64 ] =* ruby-1.9.3-p374 [ x86_64 ] # => - current # =* - current && default # * - default I've tried entering "rvm use 1.9.3 --default" but it only works for the current terminal session. Opening new terminals always reverts back to 1.8.7. I've also made sure that my ~/.bash
