Ruby on Rails missing nokogiri /nokogiri

Question

I'm doing a tutorial on Ruby on Rails from Lynda, and everything has gone the way it should. All installations and everything has worked flawless.

But after creating a project, when I try to start the server (cmd: rails server) I get the error message:

LoadError: cannot load such file -- nokogiri/nokogiri

I have * Windows 7 x64 * Rails 4.2.4, * Gem 2.4.8.

I'm in the directory of the project. All files are there, everything looks ok. I created my project like this: ruby new test_cms and I also tried this: ruby new my_cms -d mysql . Same result.

Any ideas?

Answer 1

It looks as though nokogiri isn't be loaded, so you need it. So first think to do is check that it is in your Gemfile. If it is - move it to the top (I know - strange but it sometimes sorts out similar issues). If it's not, add it:

  gem 'nokogiri'

Then run bundle install again.

Then try running bundle exec rails server to run the server with your bundle. You may be running it out of context.

Answer 2

If 'nokogirl' is located in your Gemfile maybe try updating your gems. try $ gem update --system .
