在Mac OS 10.8.3中安装滑轨时遇到问题

Question

I'm trying to install RoR following railstutorial.org which is pretty similar to this one: http://www.creativereason.com/how-to-install-ruby-on-rails-mountain-lio.html

But, when i type "gem install rails" in command, i'm getting this error and couldn't install RoR.

I'm getting this error:

ERROR: Could not find a valid gem 'rails' (>= 0) in any repository ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError) too many connection resets ( http://production.s3.rubygems.org/latest_specs.4.8.gz )

Does someone know how to fix this and install rails correctly?

Answer 1

Install RVM and ruby:

$ curl -L https://get.rvm.io | bash -s stable --ruby

Then Rails:

rvm gem install rails

Answer 2

Another possibility is that rubygems is out of date:

gem install rubygems-update

and/or

gem update --system

Answer 3

I found the solution: I had to disable Avast antivirus! Now, it's working!
