bundle exec rake test:models throws Errno::EACCES: Permission denied

Question

I am doing the draft version of the railstutorial, when I try to run bundle exec rake test:models I get this error message:

rake aborted!
Errno:         


        

Answer 1

I deleted the old test.sqlite3 and replaced it with a copy of development.sqlite3 and renamed it test.sqlite3, this seems to have solved the problem.

Answer 2

I noticed this happens if I have one terminal open running the rails server and another terminal to work on. My work Terminal is what gives me the issue when I try to drop or reset a database. I close the server ans try again and it works fine.

Answer 3

Run rake db:migrate RAILS_ENV=test before running the tests.

I'm not a rails expert, so I don't know if the test DB should be migrated automatically when migrating the development DB, but this will migrate it, and it resolved my similar problem.

Note: My OS is Windows 8.1

Answer 4

Yes, the issue is with Windows. when you read the code for fileutils.rb found in railsinstaller directory. It wants to unlink and want to give permission 700(which is found in unix/linux) but not in windows. so will not work.

Here is the snippet from the fileutil.rb file.

def remove_file
  platform_support {
    File.unlink path
  }
end

def platform_support
  return yield unless fu_windows?
  first_time_p = true
  begin
    yield
  rescue Errno::ENOENT
    raise
  rescue => err
    if first_time_p
      first_time_p = false
      begin
        File.chmod 0700, path()   # Windows does not have symlink
        retry
      rescue SystemCallError
      end
    end
    raise err
  end
end
