I am learning Ruby on Rails and I followed the installation of RVM and Rails from Ryan Bigg's blog and the Agile Wed Development book. This has worked previously on my PC at home, but at work it gives me the error:
depot$ rails -v
Could not find gem 'sqlite3 (>= 0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
I am trying to generate a scaffold but this is what i get:
depot$ rails generate scaffold Product \ title:string description:text image_url:text price:decimal
Could not find gem 'sqlite3 (>= 0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
I have sqlite3 installed, RVM 1.9.2-p320, and running on Ubuntu 11.04.
Any ideas what can be causing this and how to fix it?
Run
bundle install
in your Rails app's directory just like both error messages instruct you to.
i had the same issue you could try to run sudo apt-get install libsqlite3-dev and bundle install in the app directory.
You need to run it from your app directory so it can find the Gemfile to know which gems it needs to install from the Gemfile.
Yes. I was also having the same problem
when I started with rails, then when writing "rails new " I got this problem of sqlite3 . This appears due to the reason that "bundle install" is not executed. When we try to 'bundle install' then it will show some gemfile missing error. This happens due to the reason that we haven't changed the directory to that folder where we are using the rails application. So for solving this problem follow these steps :
type 'rails new app' // instead of app you can type any name you want.
now a folder named app will be created in your home.
now start new terminal.
type 'cd app'
now you can continue your work, and you will not face any such problem.

I'm trying to create a project with mysql as a database, ran command
rails new project_name -d mysql
got the following errors
Could not find gem 'mysql2 (~> 0.5)' in locally installed gems. rails importmap:install
Could not find gem 'mysql2 (~> 0.5)' in locally installed gems. Run bundle install to install missing gems.
rails turbo:install stimulus:install Could not find gem 'mysql2 (~> 0.5)' in locally installed gems.
Run bundle install to install missing gems. "
so i ran
bundle install
but it fails and at the end it tells me
An error occurred while installing mysql2 (0.5.4), and Bundler cannot continue
full error https://pastebin.com/jiX7V0Z0
I'm running windows (all answers I found were for linux or mac), any help is appreciated
Edit : as Christos-Angelos Vasilopoulos mentioned, answer in this issue worked https://github.com/brianmario/mysql2/issues/1210#issuecomment-965862944
what I did was the first two steps
1 - Start a cmd terminal and run ridk explicitely by running:
c:\your path to Ruby31-x64\ridk_use\ridk.cmd enable.
This gives you the right environment to do the rest.
2 - From that cmd, run
gem install mysql2 --platform=ruby -- --with-mysql-dir=c:/your path to Ruby31-x64/msys64/mingw64
(no particular quote was neeeded and I used forward slashes).
It is an open issue with mysql2 though there is a workaround. Check this thread from GitHub the last comment is the thing you need.
I've no idea what happened, but I've started getting this error:
c:\Sites\Project>ruby bin/rails server
Your bundle is locked to rake (12.0.0), but that version could not be found in any of the sources listed in your Gemfile.
If you haven't changed sources, that means the author of rake (12.0.0) has removed it.
You'll need to update your bundle to a different version of rake (12.0.0) that hasn't been removed in order to install.
Run `bundle install` to install missing gems.
I've been using railsinstaller 2.3, and after getting it switched over to 2.2, but it is not helping.
Running bundle install produces exact same error text.
Ran
gem install rubygems-bundler
gem regenerate_binstubs
then
bundle install
I'm learning Rails with tutorials from Ruby on Rails by Michael Hartl: https://www.railstutorial.org/book
I used the following command to generate a controller:
rails generate controller StaticPages home help
Which generates the following error regarding version conflicts:
check_version_conflict': can't activate bundler-1.12.4, already
activated bundler-1.13.0.pre.1 (Gem::LoadError)
I don't know which bundler version to use. The current version of bundler is: 1.13.pre.1
The following command continued failing due to about five gem dependencies that failed to install automatically, which included listen and nokigiri.
bundle install --without production
I tried installing the dependent gems manually, but I'm still having issues.
How do I resolve the check_version_conflict issue with Bundler when generating Rails controllers?
I'll accept an answer that instructs removing current Ruby libs and installing a new development environment from scratch.
Bundler will install project-specific versions of your gems so that you don't have to manage global dependencies.
In effect, if you install Rails with bundler and you also install it with sudo gem install rails or something like that, you'll have two versions on your computer. By default, calling rails will refer to the global version.
If you call bundle exec rails (or bundle exec <gem_name>), it will call the bundler-specific version.
Ten steps to resolve your issues with Bundler
(optional) Uninstall Ruby. There are many ways to do so, here's one: https://superuser.com/questions/194051/how-to-completely-remove-ruby-ruby-gems-on-mac-os-x-10-6-4
(optional) Use rbenv to install Ruby. Follow instructions here: https://github.com/rbenv/rbenv
Make a repo directory that will house your future Rails app
From the command line:
mkdir repo
cd repo
Install Bundler and create a Gemfile for the directory
From the command line:
gem install bundler
bundle init
Open the repo/Gemfile with your editor, and configure it to instruct Bundler which version of Rails to install
In repo/Gemfile:
source "https://rubygems.org"
gem "rails", "4.2.6"
Install Rails via Bundler
From the command line:
bundle install
Create a new Rails app using Bundler, and cd into it
From the command line:
bundle exec rails new whatevs
cd whatevs
Your Rails app will have a Gemfile by default. Open it and add the gems you wish to use in your app.
In repo/whatevs/Gemfile:
gem 'nokogiri', '1.6.8'
From repo/whatevs/ directory, install your app's Gems via Bundler
From the command line:
bundle install
From repo/whatevs/ directory, generate a controller
From the command line:
bundle exec rails generate controller static_pages home help
Um quite new to rails and um getting an error when run the command
rails s
it says
Could not find rake-0.9.2.2 in any of the sources
Run bundle install to install missing gems.
when I run bundle install nothing happened
my gem list has rake 0.9.2.2
what can go wrong?
my ruby version is 1.9.3
Thank you in advance
Remove all the versions of Rake ==> gem uninstall rake
Remove your gemfile.lock => rm Gemfile.lock
Remove gem 'rake' on your gemfile
Run bundle install
Install Rake manually : gem install rake --version=10.0.4
When you use command gem list, you will get a list of gem installed on your machine.
For example : rake (10.0.4, 10.0.3, 0.9.2.2)
Just see the console which gem is compatible with your application. It is already mentioned in the error log message.
Use
gem uninstall rake
Keep the suitable one and remove the version who is creating trouble. And then run rails s or bundle exec rails s
Try using rvm and go back to ruby 1.8.7 instead of 1.9.2. This fixed it for me. Don't forget to install rails again (sudo gem install rails while already on 1.8.7) if you have only installed rails for 1.9.3.]
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.
