I have a Gemfile with the following contents:
source 'https://rubygems.org'
gem 'knife-cloudstack', :git => 'git://github.com/CloudStack-extras/knife-cloudstack.git'
On doing a bundle-install, i get the following output
bundle install --binstubs
...
Using knife-cloudstack (0.0.13) from git://github.com/CloudStack-extras/knife-cloudstack.git (at master)
...
But now when i do a bundle show, bundler cannot find the knife-cloudstack gem
bundle show knife-cloudstack
Could not find gem 'knife-cloudstack (>= 0) ruby' in the gems available on this machine
I am not sure what i am missing here. Please assist
just tried the exact same thing, and seems to work fine for me. What version of ruby are you using? What's the output of "gem environment"? Does running "bundle show" show any gems? Are you running on a linux machine? if so, you might be able to find out where it writes the gems to using: "strace -f -eopen -o/tmp/strace.log bundle install"
cheers

I cannot require a custom gem I developed to a ruby project. I use RVM. Here's what I've done:
I added gem locally via Gemfile:
gem 'my-gem', git: 'https://github.com/username/my-gem.git'
I installed the gem:
bundle
Fetching https://github.com/username/my-gem.git
Fetching gem metadata from https://rubygems.org/............
Fetching version metadata from https://rubygems.org/..
Resolving dependencies...
Using my-gem 0.1.0 https://github.com/username/my-gem.git (at master#dcdac02)
Using bundler 1.11.2
Bundle complete! 1 Gemfile dependency, 2 gems now installed.
I confirmed it was installed:
bundle show my-gem
/Users/myuser/.rvm/gems/ruby-2.2.2/bundler/gems/my-gem-dcdac02a8b69
I confirmed my gem paths:
GEM PATHS:
- /Users/myuser/.rvm/gems/ruby-2.2.2
- /Users/myuser/.rvm/gems/ruby-2.2.2#global
When I run gem list, my gem is missing. When I require 'my-gem', the gem cannot be found.
When I run gem which my-gem, I get:
ERROR: Can't find ruby library file or shared library my-gem
I'm not really sure what else to try. Any ideas?
Rubygems have no concept of git installed gems, so Bundler includes a specific mechanism for loading these paths into the GEMPATH, you need to do the following before you can require them:
require 'bundler'
Bundler.setup
See the Bundler git gems docs for more info.
I would make sure the installed version of the gem has all the files you expect, especially lib and its contents. This past discussion might help you:
gem which cannot find gem despite it being installed
I found a similar issue
bundle show kubernetes_metadata_filter
/fluentd/vendor/bundle/ruby/2.3.0/bundler/gems/fluent-plugin-kubernetes_metadata_filter-0cd7e29eacec
while the rest of my gems were install here:
/fluentd/vendor/bundle/ruby/2.3.0/gems/
notice the subtle difference between 2.3.0/bundler/gems/... and 2.3.0/gems/......
HACKY SOLUTION:
after bundle install, i did the following:
gem install specific_install
gem specific_install -l <url to a github gem>
That did the trick and installed the gem to the gems directory, and not just bundler. I beleive the correct fix is the project needs to require bundler on startup, then it will get the bundler installed gems as well, but not all projects are well suited for that solution. good luck!
I'm just trying to learn to write the example-output-plugin,follow this page:
http://www.elastic.co/guide/en/logstash/current/_how_to_write_a_logstash_output_plugin.html#_clone_and_test_4
when I type the "bundle install" in the folder ~/logstash-output-example,I get the the error:
Could not find gem 'logstash-devutils (>= 0) ruby' in any of the gem sources
listed in your Gemfile or installed on this machine.
it seems the gem 'logstash-devutils (>= 0) ruby' missed,but when I type the
"sudo gem install logstash-devutils", I get the error
ERROR: Could not find a valid gem 'logstash-devutils' (>= 0)
Here is why:
Found logstash-devutils (0.0.12), but was for platform java
Anyone else can help me?
environment:MAC OSX 10.9.5
I just ran into the same problem. Solved it by just downloading the gem via the download link on its rubygems.org page and installing it with:
sudo gem install logstash-devutils-0.0.13-java.gem
That worked for me.
Update:
Well, that will install the gem but it will not solve the real problem. I needed to switch to jruby for the tutorial to work. This can be done via the RVM:
sudo rvm install jruby
I tried installing the gem manually and got a different error:
There was a RuntimeError while loading logstash-devutils.gemspec:
Only JRuby is supported from
/Users/bnewton/.rvm/gems/ruby-2.2.1/bundler/gems/logstash-devutils-15c59bfaab59/logstash-devutils.gemspec:2:in `'
This leads me to believe the logstash-devutils requires jruby rather than the usual ruby. I use rvm, so it was a matter of installing and using jruby instead of regular ruby. So if you are using rvm, run:
rvm install jruby-1.7.19
rvm use jruby-1.7.19
gem install bundler
bundle install
This fixed it for me, and I was able to run bundle install without error.
I just got Ruby motion, and I wanted to try out Cocoapods. I installed it just as it asks on the website:
http://www.rubymotion.com/developer-center/articles/cocoapods/
I add
require 'motion-cocoapods' to my simple 'Hello' project. And I get this error when trying to rake it:
rake aborted!
Unable to activate cocoapods-0.16.1, because rake-10.0.3 conflicts with rake (~> 0.9.4)
I guess this has something to do with my version of rake, but I have no idea what I need to do to fix this problem. Please help!
This is caused by having a version of rake newer than 0.9.x installed. When you just run rake, it loads up the newest version (10.0.3 in your case). Then, when the cocoapod gem tries to load, it tries to activate rake 0.9.x and fails (the ~> 0.9.4 means that it will accept any version starting with 0.9.).
One solution would be to completely remove the rake gem and install the 0.9.4 version explicitly:
gem uninstall rake
gem install rake --version '0.9.6'
However, this could become an issue if you have any other projects that require a newer version of rake. A better solution would be to use Bundler:
gem install bundler
Create a Gemfile in your project folder containing:
source :rubygems
gem 'rake'
gem 'motion-cocoapods'
Add the following to Rakefile, immediately under the require 'motion/project' line:
require 'bundler'
Bundler.require
Then run bundle install from the console. This will lock this specific project on rake 0.9.6. The only catch is that you'll probably need to prefix all of your rake commands with bundle exec.
I was able to solve this issue by following the steps on this japanese blog:
http://blog.amacou.net/post/37702092871/rubymotion-cocoapods-rake
First uninstall:
gem uninstall motion-cocoapods
gem uninstall cocoapods
download cocoapods :
git clone git://github.com/CocoaPods/CocoaPods.git
find the gemspec file
and change this:
s.add_runtime_dependency 'rake', '~> 0.9.4'
to this:
s.add_runtime_dependency 'rake', '> 0.9.4'
then install it as a gem
rake gem:install
then reinstall motion-cocoapods:
gem install motion-cocoapods
My feeling is this is a hack though, and I'm worried it could cause problems else where. If anyone has a better answer, please post it.
Seems like every Ruby tutorial I find centers around Rails.
Anyway, I simply want to install a gem from a GitHub repo and have that gem work in irb.
I want to install the exifr gem. When I do a gem install exifr it doesn't get the newest version.
So I created a Gemfile and put:
gem 'exifr', :git => 'git://github.com/remvee/exifr.git'
Then bundle install. Installs OK but now gem list doesn't find the gem. So I can't require it in irb.
Any help for NON Rails applications?
Thanks
You need to kick off the bundler setup if you want to use the gems from a gemfile:
require 'bundler/setup'
require 'exifr'
or:
irb -rbundler/setup
> require 'exifr'
This is equivalent to running bundle exec irb, except it doesn't depend on a specific invocation to work, and instead presumes that a Gemfile is available and the gems were installed with Bundler.
Try...
bundle exec gem list
And..
bundle exec irb -rexifr
And see if that works. That should help gem/irb find the installed gem.
I'm using rbenv with Ruby 1.9.2-p290, Rails 3.1, and the database is MySQL.
When I try
rake db:create
I get the following error:
Could not find multi_json-1.0.3 in any of the sources
I've also tried bundle exec rake db:create.
My GemFile looks like this:
source 'http://rubygems.org'
gem 'rails', '3.1.0'
gem 'mysql2'
gem 'json'
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
gem 'jquery-rails'
Quite old, but in case anyone else comes across this and is looking for the real answer: upgrade your bundler gem.
For me didn't work neither smathy and kalleth answers.
Always getting:
Could not find multi_json-1.3.0 in any of the sources
What it worked for me was deleting Gemfile.lock and running again bundle install
It installed a new version of multi_json:
Installing multi_json (1.3.2)
I ran into this problem too with a Rails 3.1 application + rails engines .
bundle exec rake -T reported the error you're reporting.
What solved it for me was running the following command to tell bundler to install the gems to the local 'vendor/bundle' path within the application with the following command:
bundle install --path=vendor/bundle
After I did that, bundle exec rake -T worked correctly.
I had the same problem, and used Jorge's answer to get to my solution:
bundle update multi_json
This just updates multi_json, and not all the other gems, which would potentially happen when you delete the Gemfile.lock and run "bundle install".
Always run your commands through bundle exec. That way you ensuer that you load the correct environment which is expected by your app. Use it like:
bundle exec rake db:migrate
Also make sure you have actually run bundle install to install all required gems and their dependencies.
