I am trying to set up a local Rails environment, and I am having issues with getting RVM installed.

Can I use RVM to maintain a single version of Ruby for all users?

阅读更多关于 Can I use RVM to maintain a single version of Ruby for all users?

I love RVM. I realize that the main use case for it is letting different users switch between different versions of Ruby. But let's say I'm deploying a Rails app to a server and I just want a single version of Ruby running. In particular, I want 1.9.2, which is a breeze to install with RVM but a pain without it. Is there a way that I can say "I want this to be the canonical Ruby installation for all users" (along with all of its gems) without having to create a bunch of symlinks by hand and change them every time I update to a newer Ruby release? Install RVM as root and do a sudo rvm use 1.9.2

RVM, Ruby 1.9.2, Rails 2.3.8, Passenger and “invalid byte sequence in US-ASCII”

阅读更多关于 RVM, Ruby 1.9.2, Rails 2.3.8, Passenger and “invalid byte sequence in US-ASCII”

I just started the upgrade process from Ruby 1.8.7 to Ruby 1.9.2 (using RVM). I have all my applications running using 'script/server' (or 'rails server') with 1.9.2, however, only Rails 3.0.0 RC applications work with Passenger. The error message given by Rails 2.3.8 applications is: invalid byte sequence in US-ASCII I'm guessing that this is a Passenger issue. I installed Passenger 2.2.15 using the RVM guide found here . Any ideas how to fix this bug? Thanks. I've updated to include a stack trace: /Users/kevin/.rvm/gems/ruby-1.9.2-p0/gems/actionpack-2.3.8/lib/action_view/template_handlers

when i write in the treminal "rvm list" i get this: rvm rubies ruby-1.9.1-p378 [ x86_64 ] ruby-1.9.2-p136 [ x86_64 ] but when i type "ruby -v" i get this: ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0] what shoud i do? Have you tried rvm use 1.9.2 ? Installing rubies does not make them the executable version of ruby. RVM will only make ruby the 1.9.2 version if you tell it to, with rvm use 1.9.2 or rvm use 1.9.1 If you want rvm to use 1.9.2 by default, use rvm --default use 1.9.2 Without actually looking at your system, I can't say for sure what is happening, but it would appear

Why do I need to use “rvm use default” after opening new terminal window?

阅读更多关于 Why do I need to use “rvm use default” after opening new terminal window?

On opening a new terminal window (Mac OSX 10.7.2) and entering rails , I get the always fun 'rails is not currently installed..." message. But I enter rvm use default 1.9.2 and all is good with the world. Where did I go wrong? nobody Zabba is right in the comments when he says the correct command to use is rvm use 1.9.2 --default . RVM considers default to be a Ruby, equivalent to the Ruby set to the default. If I type rvm use default into my terminal, I get this output: $ rvm use default Using /Users/tom/.rvm/gems/ruby-1.9.3-p0 However, there is the ability to list multiple Rubies in your

How to tell Bundler to use gems installed systemwide (production deployment)?

阅读更多关于 How to tell Bundler to use gems installed systemwide (production deployment)?

问题 When deploying a Rails app with Capistrano, I want Bundler to install gems to shared/bundles dir ONLY IF it can't find gems installed systemwide already. How do I do it? For example, if I have a pg gem v 0.14 already installed on the system, I want Bundler to use it and not build and install a new one into shared/bundles dir of my application. I'm using Ubuntu Server and RVM is installed for multiple users. 回答1: Bundler allows using shared (rubygems) and vendored (bundler) gems, by default

Why doesn't RVM work in a bash script like it works in an interactive shell?

If you type the command in console, it works. But if you put them in a bash script, problem comes. #!/bin/bash rvm use 1.8.7 rvm list # This shows the ruby used in parent shell's rvm. Wayne E. Seguin In the script you are most likely not loading rvm as a function. http://rvm.io/rvm/basics/ Brett The shell functions installed by RVM aren't necessarily exported to subshells. In your shell script, you can re-initialize RVM with something like the same command line that's in your .bash_profile or .bashrc: [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" After you do that, the

I'm a bit of a novice at messing around with my environment and I seem to have rather broken it. Many thanks in advance for any assistance you can offer. The main symptom is that when trying to run rvm install 1.9.3 I get the following trace: Installing Ruby from source to: /Users/duncanstuart/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending on your cpu(s)... ruby-1.9.3-p0 - #fetching ruby-1.9.3-p0 - #extracted to /Users/duncanstuart/.rvm/src/ruby-1.9.3-p0 (already extracted) Fetching yaml-0.1.4.tar.gz to /Users/duncanstuart/.rvm/archives Extracting yaml-0.1.4.tar.gz to /Users
