ruby - Would 'gem update --system' make my previously installed gems incompatible? -

-

i tried install hoe , encounted this:

installing hoe (2.9.1) /library/ruby/site/1.8/rubygems/installer.rb:170:in `install': hoe requires rubygems version >= 1.4. try 'gem update --system' update rubygems itself. (gem::installerror)

i worried update might corrupt previous installed gems...

gem update --system update rubygems itself.

previously installed gems not affected , should run before.

or there specific gem or situation worried about?
