Could not find a valid gem 'xxx' in any repository

I am attempting to install Ruby/Rails on an Windows XP box. After following these instructions - (Installing Ruby and Rails on Windows) including the comments at the bottom about Devkit.

I get an error when trying to do a 'gem install sqlite3-ruby'. The reply is 'Could not find a valid gem 'sqlite3-ruby' <>=0> in any repository.'

Any instructions on what I did wrong would be great.

Thanks!

Most likely you're behind a proxy and you are not aware of.

Please check your browser settings. take note of the HTTP proxy information and then use the --http-proxy option of gem install command.

More details in the syntax use "gem help install"

Also, you can see if your proxy is not blocking S3/CDN downloads by manually downloading in the browser one gem from rubygems.org:

http://rubygems.org/

HTH,

Using a browser I can download gems from http://rubygems.org. Does this mean I should NOT have to use the --http_proxy switch on the command line?

No, you *should* use --http-proxy option, please check your browser options about proxy connection and use that information in the --http- proxy option

You will end with something like this:

gem install xxx --http-proxy=http://user:password@server
