I am very new in Rails. after I created a new rails project.

no such file to load -- bundler/setup

Answer 1

Run:

gem install bundler
bundle install
bundle exec rake db:create

You might want to learn about Bundler.

See the link on "Creating new Rails Project".

Answer 2

I had the same thing and here's what I found: You probably have more than one version of rake installed (type gem list to see), and your project is specifying you must use the older version of rake.

If you do, then the default rake is the newer one.

If you are in your project directory, and your project's Gemfile specifies the older version of rake, and your type rake db:migrate then the error message is telling you that the 'new' version of rake is not the one you specified in Gemfile, so run bundle exec rake db:migrate so bundler can pick the correct version of rake for you.

Answer 3

try

gem install bundler

bundle install

to install the gems needed.

rake tasks will fail if you do not have the gems necessary for the rails app.

Answer 4

I just had the same issue. I didn't solve it fully but by running:

bundle exec rake <task> 

I was able to finally run the task I wanted without the error you have.
