Hi All,

1.I installed ruby 1.9.3 for win7 successfully
2. I extract DevKit 3.4.5.2 an install successfully
3.But when i run C:\Ruby193\gem install ruby-debug-base193 --http-proxy=http://10.10.10.10:8080/ but not complete
The log showed :

First point: you're behind a proxy. Remember this later on.

 

Second point: you're using ruby-debug-base193, that gem I'm not familiar with, only ruby-debug-base. The author of that gem:

http://rubygems.org/gems/ruby-debug-base193

Has no provided any link to the source code so we can see the differences between this and ruby-debug-base.

C:\Ruby193>gem install ruby-debug-base193 --http-proxy=http://10.10.10.10:8080/

ruby_core_source, a gem dependency, will attempt to download Ruby source code:

 

C:/Ruby193/lib/ruby/1.9.1/net/http.rb:762:in `initialize': A connection attempt

d. - connect(2) (Errno::ETIMEDOUT)
        from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:762:in `open'

And it is failing because you're behind a proxy.

The code in ruby_core_source is not aware that you're behind a proxy, simply because the code is not considering that scenario.

In theory, if you setup HTTP_PROXY environment variable prior calling gem install, Net::HTTP (used by ruby_core_source) should work.

Please note that I'm guessing based on some documentation, it might not work, in which case you should report to ruby_core_source author that he should add support/detection for HTTP_PROXY environment variable.
