Can't create a database in Ruby on Rails

Question

I'm following some tutorials of association in rails database, the first step is to create the app with rails new newProject -B . Then i create the two models with rails g scaffold Father name:string and rails g scaffold Child name:string sex:string father:references .

After that i try to create the database with the command rake db:create , but an error appears:

Could not find nokogiri-1.6.7.1 in any of the sources Run bundle install to install missing gems.

I run the command bundle install normally, but when i tried again, the same error appears. I tried to insert in the GemFile gem 'nokogiri', '~> 1.6', '>= 1.6.7.1' and the same error persists.

Answer 1

I had a similar issue with nokogiri a couple of months ago.

I solved it by adding '-rc3' to the end of the gem version, like this:

gem "nokogiri", ">= 1.6.7.rc3"

Answer 2

我之前曾遇到过这个问题，您可以尝试使用gem install nokigiri手动gem install nokigiri

Answer 3

Have you try

$bundle update ?

Can you post the error logs to see if it is a Permissions Error or something else?
