Starting with rails and I had a problem with 'rails s' and the following error appears:
/usr/bin/ruby1.8: symbol lookup error: /var/lib/gems/1.8/gems/therubyracer-0.11.0beta5-x86_64-linux/lib/v8/init.so: undefined symbol: rb_intern2
You should consider updating to the latest version of Ruby and Rails (1.9.2 and 3.2.7, respectively). Also, you should make sure you have the latest version of the gem by running
gem uninstall therubyracer
gem install therubyracer
Note that servers such as WEBrick need to be restarted after installing gems; you can't just install the gem, include it in your code, and refresh the page like you can with new JS or CSS.
I'm having this issue but it seems that my local version requires the beta of therubyracer (to support libv8 as it throws a compile error without it on OS X 10.8), but my production system does not (CentOS).
I tried specifying group :production do in my bundle, but it throws an error saying i've called the gem twice. http://gembundler.com/rationale.html was what had me try that.

I know the question to this is probably very straight forward, but Im a bit new to rails, so please bear with me. I have had rails version 5.1.5 on my Mac and I need to update rails to version 5.1.6 and I'm not able for the life of me to do that.
I tried
`sudo gem install rails -v 5.1.6`
but this gives the error
ERROR: Failed to build gem native extension.
Using gem list gives that I have
rails (5.1.5, 5.1.4)
I also tried bundle update rails
I keep getting Could not locate Gemfile
What am I doing wrong??
gem is the native package manager for Ruby.
Bundler (bundle) is a gem to manage bundles of gems via a Gemfile.
I recommend you use a version manager for Ruby like rvm, rbenv or chruby and also install xcode and the commandline-tools package of xcode. Some gems have dependencies written in C that need to be configured and compiled, all of that and some more comes with xcode.
So I had a rails app up and working on my hostmonster account just fine. I then updated a few things in my dev environment / pushed them up to github / pulled them back down on my production environment. Now its giving me the error Could not find pg-0.17.1 in any of the sources (Bundler::GemNotFound).
This is a new gem i installed in my dev because i was attempting to move to postgresql for dev and live....for now im using postgresql in dev and mysql2 in production. I know this isn't optimal but im working on it.
I tried running bundle install to get the pg gem installed and it fails with the error
Gem::Exception: Cannot load gem at [/usr/lib64/ruby/gems/1.9.3/cache/rake-10.2.2.gem] in /home4/muscorei/workspace/vollapp
An error occurred while installing rake (10.2.2), and Bundler cannot continue.
Make sure that gem install rake -v '10.2.2' succeeds before bundling.
I try installing rake and it works fine...try again..same error. I have found one question on here that seems to fix this for others but it requires running of gem update --system which you cannot do for hostmonster. Any ideas?
So here is another "related" issue. When i type in gem list --local I see that rails is installed at version 4.1.0....however when i do rails -v it shows the systemwide version of 3.2.13. I don't EVER have any of these annoying issues on my dev environment.
am a newbie in rails. working on Windows 7, 64 bits. Installed my environment through RailsInstaller. latest version ofcourse.
When creating a new project, (keeping the gem file as default) and having the bundle install run, am getting the error
gem::package::FormatError: no metadata found in
D:/RailsInstaller/Ruby1.9.3/bin/cashe/activereocrd-3.2.9.gem
and error occurrend while installing activerecord (3.2.9), and bubndler cannot continue.
Make sure that gem install activerecord -v '3.2.9' succeeds before building.
I tried to run the gem install activerecord..as instructed still bundle install does not work and i cannot run the rails server. (rails s)
When changing the rails version in the app gem file to 3.2.8 instead of 3.2.9 everything seems to work and the rails server runs succefully. What is wrong?
I uninstalled railsinstaller and all other leftover folders.
reinstalled railsinstaller. Problem solved.
Is there anywhere that there are step by step instructions on how to install gems?
My google-fu is weak and those that I could find did not resolve my error.
My errors are detailed here:
Getting gcal4ruby gem to work
Basically my error sums up as:
gem installs properly and is detectable by,
but whenever I try to reference it in my application it just says:
Could not find 'gcal4ruby (= 0.0.5, runtime)' in any of the gem sources Try running 'bundle install'.
(* I tried bundle install -> no help *)
Your error states:
Could not find 'gcal4ruby (= 0.0.5, runtime)' in any of the gem sources Try running 'bundle install'.
It's looking for 0.0.5 of gcal4ruby, which you don't have installed, rather you're saying yourself that the gem list -d shows:
gcal4ruby (0.5.5)
Which is not the correct version. I would recommend attempting to discover what's trying to require this older version of gcal4ruby. I think it's in your Gemfile, but I have been known to be wrong occasionally.
If this answer doesn't solve your question, then please attach the errors you're getting and your Gemfile to your question.
As a guess, you are using rails 3? Rails 3 uses a project called bundler for dependencies, so instead of installing the gem in your system ruby, add gem 'gcal4ruby to the Gemfile in the root of your app. after that, a bundle install will install the gem locally into your app.
Bundler means that rails 3 apps have their gems completely isolated from the system gems. Even if the gem is installed in the system, it will not be accessible in the app.
I'm on Mac OS X 10.6 Snow Leopard. I just updated my Ruby stuff using:
sudo gem update
Unfortunately, it broke everything. When I try to run a simple command in my website directory, like:
rails generate model User
It failed, with this error:
Could not find gem 'rails (= 3.0.3, runtime)' in any of the gem sources listed in your Gemfile.
Try running bundle install.
So I tried running bundle install rails. It succeeded! So I tried running rails. It failed. So I tried getting the Rails version by entering:
rails -v
Which failed with this error:
Could not find rake-0.8.7 in any of the sources
Try running bundle install.
But not only did it fail, it also created an empty folder rails/ruby/1.8 in my website directory.
This is a complete disaster for me as I am just a beginner in Ruby and Ruby on Rails, and even in the Terminal. Any help would be MUCH appreciated. Thanks.
all this stems from having a version of rack that is not exactly 1.0.1 iirc.
Even if you have a version ahead of it, your whole setup will not install properly.
Uninstall all versions of rack and make sure you only have that one.
As Justin said in your comments, now get rvm. Run, don't walk.
