ubuntu#server1:~$ type ~/.rvm/bin/rvm | head -1
/home/ubuntu/.rvm/bin/rvm is /home/ubuntu/.rvm/bin/rvm
ubuntu#server1:~$ which rvm
/home/ubuntu/.rvm/bin/rvm

rvm is a function
ubuntu#server1:~$ type `which rvm` | head -1
/home/ubuntu/.rvm/bin/rvm is /home/ubuntu/.rvm/bin/rvm
Running RVM works okay when you're ssh'ed into the box, but capistrano throws out RVM is not a function, selecting rubies with 'rvm use ...' will not work. errors because capistrano is using ~/.rvm/bin/rvm default do $command and it kind of bothers me. Deploying seems to work though.
I don't think this is related to Capistrano, but for reference here's part of my Gemfile:
group :development do
gem 'capistrano', '3.0.1'
gem 'capistrano-bundler', '1.1.2'
gem 'capistrano-rails', '1.1.0'
gem 'capistrano-rvm', '0.1.1'
end
Basically, my questions are
Is RVM behaving properly?
How do I suppress the capistrano error if I shouldn't be worried?

An error occurred while installing sqlite3 (1.4.0), and Bundler cannot continue.
Make sure that gem install sqlite3 -v '1.4.0' succeeds before bundling.
I tried to install earlier version on sqlite, not working.
Tried one of the solutions from stackoverflow :
gem 'sqlite3', '~> 1.3.6'
getting this error
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command sqlite3,
Please help i'm new in Rails , this is my first project in rails.
Add gem 'sqlite3' to Gemfile in the root directory of your rails project. Then run bundle install and it should install sqlite and make it available to use in your rails project.
Specify git and branch for the gem sqlite3 in your Gemfile should fix the problem.
gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"

Replace gem 'sqlite3' with gem 'sqlite3', '~> 1.3.11' which is in Gemfile in the root directory of your rails project. Then run bundle install.
I'm starting up a new rails app with the latest version of rails (3.1.3). Rails crashes when I try to start up the server. First I fixed this bug, and now I'm getting this one
ruby-debug-base19-0.11.25/lib/ruby_debug.so: undefined symbol: ruby_threadptr_data_type
There's a discussion about this going on here, but I can't make enough sense of it to get things to work.
UPDATE
I updated the version of ruby-debug
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
and have now moved on to this error
linecache19-0.5.12/lib/trace_nums19.so: undefined symbol: ruby_current_thread
Ok, it turns out that both ruby-debug and linecache needed to be manually updated to the latest versions. These lines in my gemfile did the trick
gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'
To run specs, you need to run bundle exec rspec -d spec
At last I found the problem. The debugger in RubyMine starts without bundle exec, so it doesn't use linecache19 from git. You need to install it manually.
Resolution of the problem found here: http://youtrack.jetbrains.com/issue/RUBY-9418?projectKey=RUBY
gem uninstall linecache19
gem uninstall ruby-debug-base19x
curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
gem install linecache19-0.5.13.gem
gem install ruby-debug-base19x –-pre
Make sure to uninstall all linecache19 and ruby-debug-base19x!
The following lines worked for me:
gem 'linecache19'
gem 'ruby-debug-base19x'
gem 'ruby-debug19', :require => 'ruby-debug'
(Hat tip to declan. His comment didn't work for me, but it gave me the idea to add linecache19.)
after trying all advise on stackoverflow, the following combination worked for me
gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'
I'm running Rails 3.1.3 on Ruby 1.9.3-p0 with RVM
when I set :require => 'ruby-debug' the server would not start.
It's repost from this
I also ran into this, and found the solution in Ruby 1.9.3 and ruby-debug. You need to install not-yet-officially-released versions of ruby-debug-base19 and linecache19. The currently released versions indeed cause the exception you had.
Use this gist.
#To install ruby-debug on Ubuntu ruby-1.9.3 you need to download from http://rubyforge.org/frs/?group_id=8883
linecache19-0.5.13.gem
ruby_core_source-0.1.5.gem
ruby-debug19-0.11.6.gem
ruby-debug-base19-0.11.26.gem
#Then in your console
export RVM_SRC=/your/path/to/ruby-1.9.3
# Note, your source path should be something like /home/user/.rvm/src/ruby-1.9.3-p0
gem install archive-tar-minitar
gem install ruby_core_source-0.1.5.gem -- --with-ruby-include=/$RVM_SRC
gem install linecache19-0.5.13.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=/$RVM_SRC
gem install ruby-debug19-0.11.6.gem -- --with-ruby-include=/$RVM_SRC
I tried it and it's work!
This is solve of our problems.
I wonder if anybody has the following issue:
in a jruby environment, I can do:
gem install glassfish
no problem
But if I add
gem 'glassfish'
to my Gemfile and do
bundle install
it always complain glass fish gem cannot be found.
Any solution to this? Thanks
Do you have source "http://rubygems.org" in your Gemfile? I just tested
source "http://rubygems.org"
gem 'glassfish'
and it was fine:
$ cat > Gemfile
source 'http://rubygems.org'
gem "glassfish"
$ jruby -S bundle install
Fetching source index for http://rubygems.org/
Using rack (1.3.5)
Installing glassfish (1.0.3)
Using bundler (1.0.21)
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
Having said that, please keep in mind that glassfish gem is not maintained at this time. For the alternatives, please check this blog post: http://www.engineyard.com/blog/2011/taking-stock-jruby-web-servers/
It turned out to be something wrong with the Gemfile.lock. deleted the file and reinstall fixed the issue.
I'm try to add a debugger to my rails 3.1.1 application which uses ruby 1.9.2. I have added the following to my gemfile:
gem 'ruby-debug19', :require => 'ruby-debug'
and I get the following error:
/.rvm/gems/ruby-1.9.2-p290#rails31/gems/ruby-debug19-0.11.6/cli/ruby-debug/interface.rb:55:in `block (2 levels) in initialize': uninitialized constant Debugger::LocalInterface::Readline (NameError)
by the way i have the following:
$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
$ rails -v
Rails 3.1.1
$ rvm -v
rvm 1.8.6 by Wayne E. Seguin (wayneeseguin#gmail.com) [https://rvm.beginrescueend.com/]
What made is work for me is:
sudo gem install ruby-debug19
gem install linecache19
gem install ruby-debug-base19
bundle update
rails server -u
Did you install all the prerequisites listed in rvm notes before you installed Ruby? I'm not positive, but I think readline is a dependency for MRI on Linux.
You may also follow these instructions from the RVM site:
If you have an error when compiling pertaining to readline, you may
need to attempt installing with the procedure defined below.
NOTE: Before you follow the procedure below please be sure to verify
that you have installed any dependencies for the Ruby you are
installing listed by the 'rvm notes' command. If you have not yet done
that do so then run 'rvm remove X ; rvm install X' where X is the Ruby
that you are concerned with.
$ rvm pkg install readline
$ rvm remove 1.9.2
$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr
I am trying to deploy to heroku.
Rails 3.1.0.rc4,
I get the following error from Heroku logs:
Starting process with command: `thin -p 48902 -e production -R /home/heroku_rack/heroku.ru start`
2011-06-20T11:25:44+00:00 app[web.1]: /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in `rescue in establish_connection': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) (RuntimeError)
I tried to install the activerecord-postgresql-adapter but then I get this error:
Could not find gem 'activerecord-postgresql-adapter (>= 0)' in any of the gem sources listed in your Gemfile.
So I tried to add this to my gem file
gem 'pg'
which produced this error:
Installing pg (0.11.0) with native extensions /Users/imac/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:533:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)
any ideas?
You don't have to install Postgres locally. In your Gemfile, put 'pg' in group :production, as johnny-grass suggests, and then when you run bundle, just specify --without production, like this:
bundle --without production
Unfortunately, you have to remember this argument when you run bundler, but at least you don't have to install and maintain postgres locally.
Please note that Heroku "strongly recommends against" using sqlite, saying that "Your production and development environment should be as close to identical as possible" http://devcenter.heroku.com/articles/rails3
Do you have PostgreSQL installed on your computer? If you don't then install it first, then install the pg gem.
# gemfile
group :production do
gem 'therubyracer-heroku', '0.8.1.pre3' # you will need this too
gem 'pg'
end
I found a solution in this Heroku article.
As Jared said, they suggest to create a different group for postgresql.
