Why does Ruby “script/generate” return “No such file or directory”?

Question

I am having trouble using script/generate. I am following the tree based navigation tutorial, which says to use script/plugin install git://github.com/rai

Answer 1

you may try a couple things, first, make sure since you are using rails 3 that you have run 'bundle install'. depending on how you installed rails and which version of bundler you are using, it may not be finding your rails binary to execute the rails generate .. so you may try prefixing it with bundle exec rails g but that is deprecated and you should get a warning if you call it. Also, make sure you are following ryan's instructions for rails 3 (and run bundle install once you add to the gemfile) on his library: https://github.com/ryanb/nifty-generators

Answer 2

As a shortcut to rails server, you can use 'rails s'. Similarly for the console, 'rails c'.

Answer 3

Rails 3 is your problem (or rather the cause of). Since rails 3 all of the "script/whatever" commands have been replaced with "rails whatever".

So now you want "rails generate ..." or "rails server" instead.

Be sure to watch version numbers or post dates when looking at tutorials :) linkage: Missing script/generate in Rails 3

Answer 4

There is a LOT of out-of-date information on the interwebs for Rails now as a result of it evolving quickly and being so popular. I use the Ruby on Rails Guides as my first stop for information as those pages seem to be the most current.

The rails generate info seems current.
