I am following this backbone rails turotial.
The tutorial says they are using Ruby 1.9.2 and rails 3.0.3.
I am using Ruby 1.9.3, and I created an rvm gemset for this tutorial and installed rails 3.0.3 into the gemset.
I ran bundle install which installed mysql2 version 0.3.11
When I ran rake db:create I got this error:
WARNING: This version of mysql2 (0.3.11) doesn't ship with the ActiveRecord adapter bundled anymore as it's now part of Rails 3.1
WARNING: Please use the 0.2.x releases if you plan on using it in Rails <= 3.0.x
So I ran:
gem uninstall mysql2
gem install mysql --version 0.2
rake db:create
Then I got this error:
Could not find mysql2-0.3.11 in any of the sources
Try running bundle install.
If I run bundle install it takes me back to the first problem.
Not sure what the I should try next.
place in Gemfile
gem 'mysql2','0.2.7'
then run
bundle install

I am trying to run rubocop on ruby 3.0.3 console
rubocop
and I am getting the following.
rbenv: rubocop: command not found
The `rubocop' command exists in these Ruby versions:
2.3.3
2.5.1
2.5.3
2.6.5
2.7.0
If you want to use RuboCop as a "naked" command from anywhere, you need to install it in your system gems:
gem install rubocop
Ruby needs to install the gems for each Ruby version independently.
If you are using bundler, and in a project that has RuboCop installed from its Gemfile, you can invoke that particular version using bundler:
bundle exec rubocop
I've replaced the gem mysql2 for a sqlite3 in development environment. However Rails keeps looking for it. I've tried to delete Gemfile.lock and it didn't work. I've also changed the database.yml file.
This is the error when I do rails db:create
LoadError: cannot load such file -- /home/gn09/.rbenv/versions/2.6.1/lib/ruby/gems/2.6.0/gems/arel-9.0.0/lib/arel/visitors/mysql.rb
replace gem in Gemfile
#gemfile.rb
gem 'sqlite3'
database.yml
something like this
bundle
bundle update - update Gemfile.lock correctly
rails db:create db:migrate
rails s
First uninstall ruby
rbenv uninstall 2.6.1
Then install again to get a fresh set of gems
rbenv uninstall 2.6.1
Then install bundler
gem install bunder -v '2.1.4'
Then
bundle install
I'm working on a project in ruby 2.1.10. it should be using rails 4.0.13.
I'm using rbenv.
I've installed everything, I believe. I ran bundle install for the project. eventually I got it to run.
However, now I get:
turlingdrome$ rails
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
turlingdrome$ gem install rails -v 4.0.13
Successfully installed rails-4.0.13
Parsing documentation for rails-4.0.13
Done installing documentation for rails after 1 seconds
1 gem installed
turlingdrome$ which rails
/Users/brianp/.rbenv/shims/rails
turlingdrome$ rails -v
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
turlingdrome$ ruby -v
ruby 2.1.10p492 (2016-04-01 revision 54464) [x86_64-darwin16.0]
in case it matters, I'm on a mac running 10.12.6
ETA from comment:
turlingdrome$ bundle exec rails -v
Rails 4.0.13
so, bundle exec lets me run rails. rbenv exec rails seems to work too.
So, the problem seems to be in the shim!
Rehash the shims:
rbenv rehash
Now you should be able to run only rails without bundle exec or rbenv exec.
Hi i'm new to ruby on rails
I have 3 ruby version in my computer.
In a project i had to use rails 3.2.1 and ruby 1.9.2
So I switched using rvm use 1.9.2 in terminal. But after that my rails commands are not detected.
$ rails g model abc
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
Why is this happening? And how to solve this?
You may need to differentiate your gem set that contains that specific version of rails from the old ones.
rvm use 1.9.2#new_gem_set_of_yours --create --default
And then retry installing the 3.2.1 rails
gem install rails --version 3.2.1
Or specify the new rails version in your Gemfile and let Bundler take care of it
gem 'rails', '3.2.1'
and run bundle install.
Type in your terminal
gem install rails -v 3.2.1
if it does not work, first try
rvm install 1.9.3
then
rvm rubygems current
and repeat.
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.]
