Starting rails server

[Peter Heylin]

Hi, 

My apologies if a similar topic exists already. I did search, but could not find anything related to below.

I am new to Ruby on Rails. I am currently setting up a Ruby on Rails environment on a CentOS 6.4 64-bit server. 

When I attempt to start the rails server, I get the following: 

/usr/local/lib/ruby/gems/2.1.0/gems/activesupport-4.0.3/lib/active_support/key_generator.rb:2:in `require': cannot load such file -- openssl (LoadError)

Would anyone have any advice or suggestions that might help to steer me in the right direction with regard to resolving the above error. 

Thanks in advance,

Peter

At a glance, have you confirmed that openSSL is installed in the location where the gem expects it? Also, how did you install Ruby on this machine? (Package, source compile, ?)

That sounds  like ruby's openssl bindings are missing. Make sure then openssl development headers (i think on centos that would be the openssl-devel package) are installed before you install ruby. You can build those extensions after ruby has been installed but it's probably easier just to reinstall ruby

Fred

[Peter Heylin]

@Walter - I have installed Ruby via the source compile method. I am using Ruby 2.1.1 and RubyGems 2.2.2

@all - I have just installed the package openssl-devel and re-compiled Ruby. This has gotten rid of the error relating to Open SSL. 

I am now getting a different error when I attempt to start the rails server.

Have you installed a JS runtime, like 'therubyracer' or 'nodejs', on your server?

Thanks for the reply.

I have just installed therubyracer and the error remains. 

nodejs is not installed on the server.

Hi, 

I got it sorted. Here is what I did to fix it: 

I found a commit in the Sprockets Github repo (https://github.com/sstephenson/sprockets/commit/743c1b1a6433195e440e2d863e5d4767cc41271a) when searching for a fix for the undefined method error relating to default_mime_type. I then applied this change to the following ruby scripts in the sprockets 2.11.0 gem directory: jst_processor, sass_compressor, closure_compressor, uglifier_compressor, sass_template, scss_template. 

I then edited my GemFile to activate therubyracer within my gem environment. 

Thanks for your assistance.

Javix,

ROR on Windows is basically unsupported (particularly on this list). The recommend path for you is to virtualize Ubuntu inside of you Windows setup and run ROR in Ubuntu.

Thank you, Jason, for your response.

It is totally false about Rais is not supported on Windows.

I managed to code in RoR on multiples Windows boxes without any problem. Virtualizing it with VirtualBox or something else would be a real overkill :).

Who provides that support? I’ve been on this list for several years and every time someone comes to the list asking about ROR on Windows they got hostile responses. It’s possible to do, but it is not supported by this forum. That’s what I meant by “unsupported”

Really, you are like the 12th person in the last 6 months who has asked every time someone asks Colin Law always gives the same answer: Virtualize Ubuntu if you want to run ROR on Windows.

-Jason

[Serguei Cambour]

I think it comes outside the current topic because talking about non-supporting of Rails on Windows is too vast, - rails (as gem ) depends on multiple gems; Most of them propose OS-dependent versions, including Windows.

I'm talking about sprockets gem and rails.

I don't think it is true to say that hostile responses are given, I
think it is more a matter of pointing out that most rails developers
use Linux or Mac and getting support for windows problems will be more
difficult.

Or dual boot Win and Ubuntu (my preferred route), or of course run
windows in VM inside Ubuntu for the rare occasions you absolutely need
windows.

Perfect. Two posts asserting that Rails on Windows is "supported",
zero posts actually *supporting the Windows user with the problem*.

Sounds about right :-)

The problem is that I had to download and install all the Rails related gems and their dependencies separately because of firewall and proxi restricitions (it was a real headache). The problem was due to the tilt version (1.1) in the generated Gemfile.lock file; After deleting that file and re-running

bundle install --local

everything came to normal and

rails s

comand worked without any problems. Unfortuantely, nobody of the above responders had the idea to do that. Thank s to Josh from Sprockets repo for the idea.

What version of tilt are you seeing in Gemfile.lock now?

How did it get to be 1.1 in the first place, which is an ancient
version from 2010? Are you upgrading an existing app, or possibly the
app was initially created with an old version of rails?

[Serguei Cambour]

No, I didn't upgrade the app. As I explained previously, I had to download all the gems and install them locally one by one. Some of them were dependent on 1.1, that's why I had to install it instead of 1.4.1.

Oh, I see, so you had picked up a version of another gem that required
tilt 1.1. So as part of your fix you presumably also got a later
version of that gem.

I think it was smth lik that. Anywa, it seems a bit strange: when trying to install a Rails-related gem that was dependent from exactlly 1.1 of tilt, running 'bundle install --local' was OK. But failed when running 'rails s'. And after removing Gemfile.lock and re-running bundle again, everything came to normal.

I can't see any gems in Gemfile.lock that require exactly tilt 1.1. I
wonder whether you misinterpreted the dependency for sass-rails and
sprockets for for tilt ~> 1.1. That does not mean exactly 1.1 but
anything between 1.1 and 2. Generally in that situation you should go
for the latest in the range, so 1.4.1. Presumably when you ran bundle
initially you had downloaded only 1.1. When you ran it again 1.4.1
must have been available so it used that.

By the way, it is easier to follow the thread if you insert your
replies inline rather than in front of the previous message
