Updating Rails

Rails
1

Hi there,

Brand new to RoR just reading thru agile development with rails. I’m
currently on version 2.1.0 and attempting to update to 2.1.2 however
when I issue the command ‘gem update rails’ I see the following
output:

Updating installed gems
Updating rails
ERROR: While executing gem … (Errno::EACCES)
Permission denied - /usr/local/lib/ruby/gems/1.8/cache/
activesupport-2.1.2.gem

Has anyone else come across this problem now or in the past? If so
please can you help me!!

Thanks in advance.

you don’t have permission to write in that location.

Run the update as root.

With questions like this, it’s extremely helpful
to post some details about the used OS.

Guess, it’s Linux or OS X, then you should run
it as root like:

sudo gem update rails

goes for most permission errors.

If it’s Windows, you must login as Admin I guess

Hi guys, after posting I suddenly remembered I used the ‘sudo’ command
when initially installing rails!! Have been a mac user for nearly 10
years and new to unix & the shell in os x but quickly getting the hang
of things through practice! Thanks for the swift response anyway, much
appreciated.
