Hi,

When I set the HTTP\_PROXY env var to  
user:pass@[http://proxy.monash.edu.au:8080](http://proxy.monash.edu.au:8080) and run gem to install  
Rials, I get the following error:

C:\Documents and Settings\Behrang\>gem install rails --remote  
ERROR: While executing gem … (URI::InvalidURIError)  
can not set user with registry or opaque

Any ideas what is probably causing the error and how can I fix it?  
(The environment is Win XP)

Regards,  
Behi

It should be

[http://user:removed\_email\_address@domain.invalid:8080](http://user:removed_email_address@domain.invalid:8080)

if I remember correctly

You can also set this up in your .gemrc-file
