Unable to install Rails

Rails
1

Hello,

I’m currently encountering a strange issue when Im trying to install
Rails for a new project. Id like to work with the latest versions, so
this is my initial starting point:

C:\Windows\System32>gem env
RubyGems Environment:

  • RUBYGEMS VERSION: 1.7.1
  • RUBY VERSION: 1.9.2 (2011-02-18 patchlevel 180) [i386-mingw32]
  • INSTALLATION DIRECTORY: C:/Ruby/1.9.2/lib/ruby/gems/1.9.1
  • RUBY EXECUTABLE: C:/Ruby/1.9.2/bin/ruby.exe
  • EXECUTABLE DIRECTORY: C:/Ruby/1.9.2/bin
  • RUBYGEMS PLATFORMS:
    • ruby
    • x86-mingw32
  • GEM PATHS:
    • C:/Ruby/1.9.2/lib/ruby/gems/1.9.1
    • H:/.gem/ruby/1.9.1
  • GEM CONFIGURATION:
    • :update_sources => true
    • :verbose => true
    • :benchmark => false
    • :backtrace => false
    • :bulk_threshold => 1000
  • REMOTE SOURCES:

When I run the following command : gem install rails I receive the
error message:

C:\Windows\System32>gem install rails
Fetching: activesupport-3.0.5.gem (100%)
ERROR: While executing gem … (Gem::FormatException)
builder-2.1.2 has an invalid value for @cert_chain

Is this related to the H: directory in the GEM PATH? Or am I missing
something?
