bundle install request to do each gem install manually - how to avoid?

Question

This is probably very simple question.
Each time I do "Bundle install" in the folder of the project I get an error like this

 An error occured while installing json (1.6.6), and Bundler cannot continue.
 Make sure that X succeeds before bundling.

where X can be
'gem install json -v '1.6.6'
or
'gem install execjs -v '1.3.2'
or 'gem install coffee-script -v '2.2.0'

Now, after I gradualy do each gem install manually the bundle install succeeds.
Is there a way to do them all in one command?
is there a way to do it in ruby mine?

Answer 1

That's what Bundler is supposed to do for you.

It looks like you have a problem with your Bundler or Ruby Install somewhere.

Without more information I can only suggest that you checkout the Bundler Troubleshooting page.

Answer 2

I've run into the same problem before if my network connection was an unstable/low bandwidth wireless connection. It tries to install all the gems at once, but stalls on one of them because of the lack of bandwidth. Then you can of course install one at a time maybe, but if your connection keeps going in and out this may be the cause of your inability to install them all at once.
