I was following an online tutorial to create an Ruby on Rails application on App Engine.
There is one command which other people can run, but it didn't run on my Ubuntu 10.10:
ruby script/plugin install http://svn.avdi.org/nulldb/trunk/
When I try to run it, it complains: ruby1.8: No such file or directory script/plugin (LoadError)
What is wrong with my computer?
ruby -v ==> 1.8.7
rails -v ==> 2.3.10
gem -v ==> 1.3.7
if using rails3, cd into your rails app root dir then use
rails plugin install http://url/of/your/package
If you are using Rails 3, you no longer have a script/plugin directory.
Rails 3 now runs commands through the "rails" script.
You can find your version of rails with rails -v
I had similar problem with rfacebook on rails 3
solution that worked for me:
cd \MyAppName\app
rails plugin install svn://rubyforge.org/var/svn/rfacebook/trunk/rfacebook/plugins/rfacebook
Have you tried just plain old script/plugin install http://svn.avdi.org/nulldb/trunk/ ? Also are you sure that you're in the correct directory?(the rails project main directory) And are you sure that you have the file script/plugin?
First of all make sure that you are running that command from the root of your rails app.

This may sound very basic to many of you. I have just started a Ruby on Rails tutorial in Linux. I'm very new to the Linux OS. I have installed a rvm. But I am unable to install Rails. It's saying "cant load such file --zlib". And I can see two source files for Ruby. Not sure if I have two Ruby installed.
Just take a note that you have selected the correct build system:
"Tools -> Build System -> Ruby"
Then press CTRL+B.
This should work.
You can execute .rb file in sublime using ctrl + b.
It seems you are a bit confused about how Ruby on Rails work.
Sumblime can run your ruby code but not on Rails stack.
My suggestion it's to work always with an open terminal on the directory of your rails application.
Let's assume you created a new rails project as
rails new helloWorld
The rails generetor will create a subfolder helloWorld.This will be your working directory in the terminal.
So you have to do:
cd helloWorld
and then
rails s
It will run your rails application on an embedded server on localhost:3000 by default.
What method did you use to install ruby?
If you compiled from source you may need to do
sudo apt-get install libssl-dev
And then recompile ruby
Otherwise, you may not have the most recent version of Rubygems
Try:
go to https://github.com/rubygems/rubygems/releases/tag/v2.2.3
download rubygems-update-2.2.3.gem
call the directory where the file was dl'ed, then
gem install rubygems-update-2.2.3.gem
update_rubygems --no-ri --no-rdoc
rubygems --version #Should show 2.2.3
gem install rails
I entered a existing ruby application, and type:
$ rails s
wanted to start rails server here.
but it said:
Your Ruby version is 1.8.7, but your Gemfile specified 1.9.3
Actually, I had a 1.8.7, but I deleted it. And if I do:
$ ruby -v
it said:
ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin11.4.2]
So I don't know how can I fix it. Can you give me a help?
If you are using rvm, run this:
$ rvm use 1.9.3
try using bundler
bundle exec rails s
I had similar problem:
$ bundle install
Your Ruby version is 2.1.0, but your Gemfile specified 1.9.3
but:
$ ruby -v
1.9.3-p484
$ which ruby
/home/malo/.rvm/rubies/ruby-1.9.3-p484/bin/ruby
I've found five answers: 1, 2, 3, 4, 5. Also it was open issue on github. However, I've resolved the problem as follows:
Got path to my bundler:
$ which bundle
/home/malo/.rvm/gems/ruby-1.9.3-p484#global/bin/bundle
Opened it to edit (or just cat it), and saw that it has invalid link to ruby in the first line:
$ cat $(which bundler)|head -n 1
#!/home/malo/.rvm/rubies/ruby-2.1.0/bin/ruby
Then I get the path to current valid ruby, and just replaced that invalid with it:
$ which ruby
/home/malo/.rvm/rubies/ruby-1.9.3-p484/bin/ruby
Of course you can also try replace it with the common form:
#!/usr/bin/env ruby
This should pick up the currently used ruby version.
I found out the reason I was getting this error was that I was shelling out to a Heroku command line program inside of my configuration files and Heroku Toolbelt comes with it's own version of Ruby.
The two solutions to that problem are to either not shell out to Heroku or use a Bundler.with_clean_env block instead of the backticks to shell out the heroku command.
Please try this:
1. Open your gemfile
2. Specify rails version
3. Run bundle update
4. Run rails server - rails s
Every now and then this happens with me. However I often don't like switching ruby versions here and there. So instead what I do is I just go to the Gemfile and switch the ruby version to the one that I am using. Doing this allows me to fire up my server and keep working on things.
so for instance, right now for the app i'm working on, my Gemfile is at
ruby ENV["CUSTOM_RUBY_VERSION"] || "2.1.6"
and I would just alter it to
ruby ENV["CUSTOM_RUBY_VERSION"] || "1.9.3"
Hi there thanks for looking into this.
after a clean install of Linux ubuntu 10.10 i tried to re-install rails.
after doing sudo gem install rails, I can see I am returned version 3.2.3 of rails
But after generating a new project i couldn't find my gemfile so i tried ruby -v which returns 2.3.4 wich is odd since I know I got the latest.
Also when trying sudo gem update --system I get an error because I might override system files. any solution here?
I'd recommend using rvm to manage your ruby sets -- as well as defining gemsets for each project that will allow you to make sure each project has just the gems it needs.
Here's a link to the rvm installation instructions (they should work with ubuntu):
https://rvm.io/rvm/install/
Here's some info on basic use of gemsets with rvm:
https://rvm.io/gemsets/basics/
Also, when using rails 3+, you should make a practice of typing bundle exec rails -v -- that way you'll use the gems defined for the project you're in.
Can you try typing bundle exec rails -v and letting us know what you see?
I am trying upgrade Rails. I am pretty sure that Rails 3.1 is now installed, however my rails apps still have no Gemfile, and rails -v returns 2.3.5. When I type "gem uninstall rails" I get:
aheine#ubuntu:~/www$ gem uninstall rails
Select gem to uninstall:
1. rails-3.0.9
2. rails-3.1.0.rc1
3. rails-3.1.0.rc5
4. All versions
How can I get rid of Rails 2, and make rails 3 the default version to use?
I am using Ubuntu 11.04
Your running with the system provided Rails, run apt-get remove rails and then you may need to make a configuration change so the system can find the proper rails command. So see if that works and then try running rails -v if that returns command not found add this line to the beginning of your .bashrc file in your home directory.
export PATH=/var/lib/gems/1.8/bin:$PATH
After that's done open a new shell and try running rails -v again.
I am trying to install LESS in a Ruby on Rails project. I am able to run the gem successfully, but when I try to install the plugin for LESS, I get an error. Here's what shows in the terminal:
MacBook:benji jesse$ sudo gem install less
Successfully installed less-1.2.21
1 gem installed
Installing ri documentation for less-1.2.21...
Installing RDoc documentation for less-1.2.21...
MacBook:benji jesse$ sudo script/plugin install git://github.com/cloudhead/more.git
sudo: script/plugin: command not found
I am a .NET developer trying to learn Ruby on Rails (on a Mac), so I am new to all this stuff.
My question's are:
Is the script/plugin command a standard command?
What does it do?
Where can I learn more about this command?
Why does it say command
can't be found?
Is the script/plugin command a standard command?
It is in rails 2, it has changed in rails 3:
rails plugin
# or
script/rails plugin
What does it do?
installs the given plugin into the RAILS_ROOT/vendor/plugin, but you should look if there is a gem version of the plugin, than you can add a gem dependency to this gem.
Where can I learn more about this command?
run the command without any parameters
Why does it say command can't be found?
try ls script/ and see if the file exists.
You have to be in the application directory. Say you created your rails app in the folder development/rails_app. You must execute the script/plugin command from there (and you don't need super user permissions for that):
cd development/rails_app
script/plugin install git://github.com/cloudhead/more.git
The plugin installation will apply only to the current rails application (in this case, rails_app). So if you create another application, you must run the script/plugin command again.
