ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
I apparently have all gems in my system, but when I run the command: gem install rails -v 4.0.0
it states that one gem was installed. But Rails isn't installed yet.
When I use gem install rails -v 4.0.0
or gem install rails --version=4.0
occurs that:

How I can install Rails 4.0.0 using RVM?
Almost seems like running 'gem install' adds it to the global available gems (and hence terminal can run the package's commands), whereas adding it to the gemfile and running bundle install only adds it to the application. Similar to npm install --global. that's basically it.
Installing Gems The install command downloads and installs the gem and any necessary dependencies then builds documentation for the installed gems. Here the drip command depends upon the rbtree gem which has an extension.
These error messages are being created while the Rails documentation is being installed on your machine. I found two Rails issues discussing this: #9590 and #11814.
This is ultimately an issue with rdoc and ruby 2.0 that was fixed but isn't in a released version of rdoc yet.
There are a few ways to get around this, I'm listing them in the order I would probably try them:
Don't install the documentation with the rails gem; instead of running gem install rails
do gem install rails --no-rdoc --no-ri
. I hardly ever use built in documentation anyway, so I actually have gem: --no-ri --no-rdoc
in my ~/.gemrc
file so that documentation is never installed for any gem.
Install rails without documentation as in #1, but then build the documentation by hand using rdoc and the --exclude='.dat'
flag, like rdoc --exclude='.dat' activesupport/lib
to build the activesupport docs, as recommended in this comment.
Install rdoc from github at a commit that is later than ceb81dd11. Using bundler's git
or github
options in your Gemfile make this easy, but there must be other reasons that a new version hasn't been released yet, so there might be bugs.
