copy app to another server

[Robert Fitzpatrick]

I've only dealt with PHP or ASP in the past, brand new to Ruby on Rails
and trying help with an existing app. I've copied a production app to
another server for development and troubleshooting, which is running
Apache 2.2 on Ubuntu 12.04 LTS. I installed ruby and passenger module as
the root user, when I pull up the site in a browser, I get 'Web
application could not be started' with the following message....

"It looks like Bundler could not find a gem. Maybe you didn't install
all the gems that this application needs. To install your gems, please run:

bundle install"

When I try to to run as root, it warns that I should not run Bundler as
root and that the Gemfile lists several gems more than once. I tried
running bundle install on the production server, which was setup using a
sudo user, it finishes successfully as complete with no warnings. When I
try to run as my own sudo user on the development server I'm trying to
copy to, it errors...

"The program 'bundle' is currently not installed. To run 'bundle'
please ask your administrator to install the package 'ruby-bundler'"

I did install ruby via rvm as root, so I do not have an .rvm directory
under my home directory as the sudo user. I have /usr/local/share/rvm,
but can't find any bundle or gem command in the bin directory under that
location. Should I have installed something as a sudo user or should I
continue to run the bundle install as root?

Thanks in advance for any help.

You should never run bundle as root (or using sudo). When deploying, all the gems get installed to <yourapp>/vendor so there should not be any need for elevated permissions. I don't recall off the top of my head whether rvm installs bundler by default - it doesn't then you do need to install the bundler gem (which for a systemwide rvm install does require running as root.

rvmsudo gem install bundler

will use sudo to do this, while preserving the environment variables RVM needs

Thanks for the help. It successfully installed the bundle under my user,
but get this error when trying to run 'bundle install':

Fetching source index from https://rubygems.org/
Could not find sprockets-2.2.2.backport2 in any of the sources

But interesting to find those seem to be commented out in the Gemfile:

$ grep sprockets Gemfile
# gem 'sprockets-rails', '=2.0.0.backport1'
# gem 'sprockets', '=2.2.2.backport2'

I found some info about trying 'bundle update' and that gives an error
as well:

$ bundle update
<snip warnings about gems listed more than once in Gemfile>
Updating https://github.com/alicetragedy/pagedown-bootstrap-rails
Updating https://github.com/ruport/ruport.git
error: cannot open .git/FETCH_HEAD: Permission denied

My user owns the app directory I am running this in, is there some other
directory git is trying to use?

Having run bundle as root may well have left some directories owned by root.

Where bundler tries to write files to depends on how its configured - (the .bundle/config file, if it exists may have some of these settings). In a production environment passing --deployment should result in everything being installed in your app's directory (or in whatever --path setting you have previously passed).

I have not ran bundle completely, but I guess it could have altered some
directories when I ran it the first time and hit Ctl+C while it was
still trying to download and after seeing the warning not to run as
root. I don't have a .bundle directory in the app directory or in my
user home directory. I do see a .bundler directory in my home folder,
but no config file, just cache. I cleaned it out and ran bundle update
again to find the folder recreated and references to ruby 1.9.1, which I
did install the Ubuntu package once but thought removed after reading
that is was broken and all examples I find suggest using rvm to install
ruby. I last used rvm to install ruby 1.9.3p392. I was trying to match
the version of the production server where I copied this app from. So it
seems something is messed up with versions. Also found I had the Ubuntu
version of rvm when I had also downloaded via curl.

Anyway, since I seem to have screwed this install up with no experience
setting up ruby and have learned a lot here and reading since my first
try, I decided to start over and completely remove ruby and rvm. I used
this to remove...

http://stackoverflow.com/questions/9056008/installed-ruby-1-9-3-with-rvm-but-command-line-doesnt-show-ruby-v/9056395#9056395

I installed all before as root, this time as my own user using sudo and
this to setup ruby with rvm except I did line 7 as 'rvm install
ruby-1.9.3-p392' and adjusted line 8 with same version:

https://www.linuxcasts.net/casts/ubuntu/1004.shtml

My question now is if rubygems current is acceptable? I'm not sure what
version the production server is running, should that be checked and
matched as well?
