Does anyone know what's happening here?
root#ip-172-31-5-114:/home/bitnami/htdocs/kicksharer/kickscraper# gem install rails
Successfully installed rails-5.0.0.1
Parsing documentation for rails-5.0.0.1
Done installing documentation for rails after 0 seconds
1 gem installed
root#ip-172-31-5-114:/home/bitnami/htdocs/kicksharer/kickscraper# bundle show rails-5.0.0.1
Could not find gem 'rails-5.0.0.1'.
Any suggestions for troubleshooting would be really appreciated.
When you gem install rails it installs it on your system. You need to make sure rails is specified in your gem file and then bundle install in order to install those gems in the bundle. (It should use the already installed gems on your system)

I have a new Mac computer and installed rails on it, and then I tried out the command
gem outdated
for some reason, it showed one of the gems outdated:
webrick (1.4.2 < 1.6.0)
I wonder why it is outdated on the first installed, and when I did
sudo gem install webrick
it actually installed 1.6.0 onto the system. Doesn't it require gem update instead of install to update something? How come install also updated it?
Not exactly, gem install GEM_NAME will install the last version available if you don't specify a version when installing, and you can have more than 1 version of the same gem on your machine.
you can run gem environment, and check where gems are installed, go to that folder and you will see both version gems folder there.
so when you create a rails project for example and add a specific version of a gem in the gemfile and another version on another project, you can have both without problems
I'm having a problem with the rails
bundle install
command not being able to find a local gemfile.
The gem is located here::
~/.gem/ruby/2.1.5/gems/mygemname-1.5.0.SNAPSHOT
I included the gem in my Gemfile. But when I try to bundle my application, it get this error::
Could not find gem 'mygemname-1.5.0.SNAPSHOT' (>= 0) ruby' in the gems available on this machine.
I can see the gem sitting on my hardrive, but the bundle install command says it doesn't exist. Does anybody have any ideas on what may be going on here?
Thanks for your time.
As I can´t comment yet...
I would check:
- Is it really the .gem folder holding the gem or is it symlinked (I am not confident that symlinks work on bundle install)
- Is rbenv or rvm in the game and is the installed gem installed with one of those or globally?
As the question states - where does the gem install?
Is it installing within the app directory that I'm working in (i.e. user/sites/sample_app)? Or is it being installed on my computer? If the latter where exactly?
Thanks!
gem install process
first download gem and save desktop
1.next step open command prompt and set location that means c:/desktop> gem install --local "gemname"
2.next step com to rails consoler and type $bundle install --local.
3. type the gem name on gem list
I have two questions:
Where do you install your ruby?
Did you use RVM or rbenv?
Now I will explain your question using my situation as an example.
I use RVM to manage rubies on my mac os.
now the ruby install in path
/Users/pin/.rvm/rubies/ruby-2.1.1
and these will be a gems directory under .rvm path. In this directory,
/Users/pin/.rvm/gems
there are many gems group, I have a group named
ruby-2.1.1#global
which is used by the default ruby version.
This is a directory and there will be a gems directory under it.
/Users/pin/.rvm/gems/ruby-2.1.0/gems
In this directory, you will find all of the gems you installed using cmd
bundle install
If you don't use ruby version management tools like rvm or rbenv, you may find the gems
around your ruby path. If you still can't find them, you can post the details of how you
install the rubies and other system configs, so that we can discuss here.
If you are using rvm then its get installed in
/home/user/.rvm/gems/ruby-version#global/ or /home/user/.rvm/gems/ruby-version/
If you are using specific gemset for gems then
/home/user/.rvm/gems/ruby-version#gemset_name/
If you want to know where gem is installed use gem which *gem_name* e.g.:
gem which rails
If you installed your gems with bundle install use bundle show *gem name* e.g.:
bundle show rails
Gems
If you use gem install x, you're adding the gem to the local ruby version on your system. This is a system-wide installation, and will be stored in your rubylib/ruby/gems dir:
The install command downloads and installs the gem and any necessary
dependencies then builds documentation for the installed gems.
Bundler
Using the bundle install command (when you have a Gemfile & use bundler), you basically tell bundler to install the gems relative to your specific applicaiton:
Bundler makes sure that Ruby can find all of the gems in the Gemfile
(and all of their dependencies). If your app is a Rails 3 app, your
default application already has the code necessary to invoke bundler.
If it is a Rails 2.3 app, please see Setting up Bundler in Rails 2.3.
For example, if you have a Rails 3.2 app, and a Rails 4.1 app on your system, using bundler allows you to instal the dependencies (gems) for each app independently
If you use gem install x, it will install the gem for all applications, and should only be used for things like rmagick and the database connection gems
Generally, if I need a gem, I put it in the Gemfile and bundle install. However, I don't understand if there is a benefit to downloading the gems locally first with gem install _____. Is there any benefit to this? Does bundle install no longer have to connect to the net in that situation?
Bundler installs the gems located in your Gemfile locally the same as if you ran gem install for each of those gems.
Gem install needed for gems that can be used outside of bundler applications. For example request-log-analyzer need to be installed outside of any apps for be available in command line.
I myself use gem install _______ then i use bundle install --local which doesn't require internet connection if the gem is found locally but will return an error if the gem was not found locally...
I find this method faster in downloading and installing gems, plus if the gems are found locally then i have also the benefit of altering the gemfile and install the gems without having internet connection.
I have installed ruby193 and I've installed rails via the command prompt (I also installed a DevKit). However, whenever I try the command:
rails server
I get this error:
←[31mCould not find gem 'jquery-rails (>= 0) x86-mingw32' in the gems available
on this machine.←[0m
←[33mRun `bundle install` to install missing gems.←[0m
I've tried a bundle install and it gives me an error with when trying to install the json gem. Any suggestions?
make sure in your Gemfile you are including the right gem (no misspellings, etc)
Looks like you are on Windows.
I defeated the very same problem on Windows by manually installing my gems from Gemfile (gem install gem_to_install). After successfully installing a particular gem I ran bundle check to see what else I need to install. And this way after few installed gems I ran bundle check again and saw the output The Gemfile's dependencies are satisfied.
And then server started. I wish you the same!
P.S. You can install few gems at once: gem install gem1 gem2.
