rvm

问题 So I'm trying to install Ruby 1.9.3 on my Mac running Mountain Lion. I have xCode installed and up to date. I've installed RVM and now am trying to install Ruby using rvm install 1.9.3 When I run this it looks like it's going to install but gives me an error please see below: rvm install 1.9.3 Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p392. Continuing with compilation. Please read 'rvm mount' to get more information on

问题 I'm busy writing up a Capistrano deployment script for one of our applications. One of the steps installs RVM using the following command: run "cat ~/rvm-installer.sh | bash -s stable --ruby" However, I feel the output is too verbose, and I rather want to dump it into a .log file. Is it possible to redirect the output for the entire rvm-installer.sh script elsewhere? 回答1: Like this: run "cat ~/rvm-installer.sh | bash -s stable --ruby >out.log" or, if you want to redirect standard error stream

问题 I would like to install RVM in an offline machine - I can manually transfer any file needed, but it'll be impossible to have an internet connection. Not being online causes RVM to collapse when trying to download source files for ruby or other dependencies (zlib, etc). I'm looking for a way to point RVM to the location of ruby source folder, e.g. something like rvm install 1.8.7 --source=/path/to/ruby-1.8.7-p330/ , or any other dependencies. I've scoured the rvm docs but either missed

问题 I have rails 4 and that's my default version (and I still wants it to be). but I d'like to add rails 3.2 on my computer. On the following command: gem install rails -v 3.2.16 I have this Warning: railties's executable "rails" conflicts with rails Overwrite the executable? [yN] I d'like to know if this will cause some bugs to my 4.0.1? 回答1: You should use rvm and install rails 3 into a new gemset. Exactly do steps as follows: Install rvm.

问题 I am having some struggles with bundler and rake. According to the error message, bundler can't find rake-10.3.1. Here's the thing, everything I've done seems to indicate that rake-10.3.1 is installed. I've been floating in the google-sphere for days without finding a solution that resolves this issue for me. I'm on Mac OSX 10.8.5. Ruby version is 1.9.3-p392. Error: bundle exec rspec spec/bdr_pre_dev_spec.rb /Users/dru.solis/.rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.6.2/lib/bundler/spec

问题 There's a two year old blog post here explaining how to fix the error 'you 'have to install development tools first' error that comes with Nokogiri, a problem that arises if you upgrade to Mountain Lion after having installed RVM. In the blog post he says you have to do rvm update head rvm --force install 1.9.2 gem install bundle ## in your rails app bundle Installing nokogiri (1.4.2) with native extensions ... rvm update head has now changed to rvm get head . However, after that I blindly

问题 I am learning Ruby on Rails and I followed the installation of RVM and Rails from Ryan Bigg's blog and the Agile Wed Development book. This has worked previously on my PC at home, but at work it gives me the error: depot$ rails -v Could not find gem 'sqlite3 (>= 0) ruby' in the gems available on this machine.
