LoadError：无法加载此类文件-ffaker

Question

Please forgive my ignorance. I'm having issues raking my database on heroku. When I run :

heroku run rake db:migrate

I get

rake aborted!
LoadError: cannot load such file -- ffaker

I've tried following the solutions from heroku rake db:migrate > no such file to load -- faker with no luck. I really am not sure where else to go from here. I would greatly appreciate any help. Thanks.

Answer 1

您应该在代码中指定此代码：

require 'ffaker'

Answer 2

Also, make sure you have ffaker in the right gem group. I was setting up a staging environment and wanted to load dummy data and forgot ffaker was only in development and testing environment groups.

Answer 3

I was using the git URL to add ffaker in my Gemfile. I removed this URL, run bundle again and everything works ok now.

-  gem 'ffaker', '~>2.10.0', git: 'https://github.com/ffaker/ffaker.git'
+  gem 'ffaker', '~>2.10.0'
