Building a Ruby stack on Windows Server: msvcrt-ruby18.dll

Question

I'm attempting to run mongrel_rails, but I get the following:

    the program can't start because msvcrt-ruby18.dll is missing from your computer

Ruby then gives me the following:

    C:\Users\Administrator>mongrel_rails
    C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 126: The s
    pecified module could not be found.   - C:/Ruby193/lib/ruby/gems/1.9.1/gems/mong
    rel-1.1.5-x86-mingw32/lib/http11.so (LoadError)

            from C:/Ruby193/bin/mongrel_rails:19:in `load'
            from C:/Ruby193/bin/mongrel_rails:19:in `<main>'

I've tried to uninstall json and reinstall with --version=ruby to no avail. I've also tried using mongrel --pre, which results in a different set of errors:

    NOTE: Gem::SourceIndex#each is deprecated with no replacement. It will be remove
    d on or after 2011-11-01.
    Gem::SourceIndex#each called from C:/Ruby193/lib/ruby/gems/1.9.1/gems/gem_plugin
    -0.2.3/lib/gem_plugin.rb:112.
    !!! Path to log file not valid: log/mongrel.log
    mongrel::start reported an error. Use mongrel_rails mongrel::start -h to get hel
    p.

My stack looks like this:

Answer 1

Seems you're trying to install binary gems for Mongrel on Ruby 1.9.3 when mongrel binaries only work for Ruby 1.8.x

Mongrel hasn't been updated to work with latest Ruby or Rails, so please avoid using it at this time.

You can use Thin as alternative:

gem install eventmachine --pre
gem install thin

The pre-installation of eventmachine pre-release version is required since latest stable 0.12 does not work with Ruby 1.9.x on Windows.

Also, if you're using a version of Windows Server, please ensure Ruby executable (ruby.exe) is added to the DEP exclusion list:
