This question should be addressed to the rubyonrails talk list not
core (which is for rails development issues).
(Hint - run bundle install after modifying gemfile.)

All true, and this provokes the issue: can we set up the initial install to 
provide reasonable defaults so that it would "just work" out of the
box?
Has this been discussed?

The defaults already are reasonable, in my opinion. I wouldn''t mind
hearing
a concrete proposal to improve them, though.

Working outside-in, I''d say our goals should be:

* A person can install and run a new rails app without "error"
messages.
* If an "error" message must be shown, then it should clearly describe
(1)
the source of the error, and (2) what''s needed to remedy it.

So IMO the current set up isn''t reasonable because (1) the behavior is 
designed-in (I.e., we''ve designed Rails to fail) yet (2) we''re
telling the
user they''ve made an error. Also, (3) the error message is really just
a
fall-through which doesn''t give a high level semantic understanding of 
what''s going on.

Contrast this with the more helpful message of rake''s checking for 
db:migrations which haven''t been run.

I realized I could be more concrete. To achive the goals I named, we should:

* Attempt to use or install a default javascript runtime. (I don''t have
the
background to know if this is possible. It seems like an odd thing for the 
system to get hung up on, though.)
* If that fails, arrange for a more helpful error message, a la db:migrate.

With respect, I think this might be where you''re getting tripped up.
Most platforms _do_ come with one pre-installed, but there are
sometimes cracks. For instance, Windows is _supposed_ to have a
default Javascript runtime installed: JScript. But you can''t ever be
100% sure of what people''s PATHs are, if they''ve screwed
around with
things...


I''m not sure how the error message could be made better: it says
exactly what to do to address the problem.
