问题 When I run rake db:migrate in Ubuntu Terminal I keep getting the error: rake aborted! You have already activated rake 10.0.4, but your Gemfile requires rake 0.9.6. Using bundle exec may solve this. I saw on stackoverflow a way to solve this problem is to run: bundle update rake So I do this and I get: Fetching gem metadata from https://rubygems.org/....... Fetching gem metadata from https://rubygems.org/.. Enter your password to install the bundled RubyGems to your system: Using rake (0.9.6)

问题 I installed the gcc-4.2 and got Ruby 2.0.0 installed, but in the process I deleted some older versions of ruby. Specifically, Ruby 1.9.3, now I want to go back and install that version using rvm install 1.9.3 but I keep getting errors. It is using gcc-4.2 to install, but gcc-4.2 is buggy to install 1.9.3. How do I install 1.9.3 now that I am in this state? Any thoughts or suggestions? These are the errors: Error running '__rvm_package_extract /Users/marty/.rvm/archives/yaml-0.1.4.tar.gz

问题 I am on Mac OS an I am running Snow Leopard Version 10.6.8.

阅读更多关于 RVM and Passenger: No such file to load - bundler

问题 I've seen other similar errors, but none of the solutions have worked for me: On Snow Leopard, I'm using RVM with project-based gemsets. I have both Rails 2 and Rails 3 apps. When I use bundler with Rails 2 or with Rails 3, I get: no such file to load -- bundler In my Rails 2 apps that don't use bundler, I just get a message that Rails needs to be installed when it is. My RVM install has a global gemset with REE version of Ruby. $ rvm list rvm rubies => ree-1.8.7-2011.03 [ x86_64 ] ruby-1.8.7
