Gem::FilePermissionError

while i updating my rails version with command,

gem install -v=2.3.8 rails

i got,

ERROR: While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /usr/lib/ruby/gems/1.8
directory.

how could i solve the problem?

Try,

sudo gem install -v=2.3.8 rails

or su to root before you run the command.
