Hi Everyone,
For most of my time working with Rails I have installed gems using a
command like this from the command line:
sudo gem install blahblah
and this has worked great.
Now I am seeing more and more install instructions for gems that call
for adding a line like
config.gem 'blahblah'
to your config/environment.rb file and then entering the following:
rake gems:install
Why the difference? What are the advantages to the second approach?
If you have have multiple lines in config/environment.rb file like:
config.gem 'abcdef'
config.gem 'xyzzzz'
and then run "rake gems:install" will existing gems be reinstalled or
updated? If yes, how do you prevent this from happening?
I suppose these questions might fall into the "dumb" category but I
don't know the answers and I'd like to learn more about how this works.
Thanks, Ken
