Solve the rails upgrade problem

First, execute:

 
C: \ Ruby> gem install railserror: While executing gem... (GEM: remotesourceexception) HTTP Response 302
 

Failed to install rails because the gem version is too low. My current version is:

 
C: \ Ruby> gem-v0.9.4
 

Now, you need to upgrade it first. You can download it from this connection address:

Rubygems-update-1.3.7.gem, http://rubyforge.org/frs/download.php/70695/rubygems-update-1.3.7.gem

You can also download: http://jifeng3518.download.csdn.net/from my csdn/

Then run CD under cmd to the directory where the rubygems-update-1.3.7.gem is located:

 
C: \ Ruby> gem install -- local rubygems-update-1.3.1.gemSuccessfully installed rubygems-Update, Version 1.3.1
 

The update is not completed yet. The next step is crucial.
