LoadError：無法加載此類文件-ffaker

Question

請原諒我的無知。 我在heroku上耙數據庫時遇到問題。 當我跑步時：

heroku run rake db:migrate

我懂了

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

我嘗試遵循heroku rake db：migrate的解決方案>沒有要加載的文件-造假者沒有運氣。 我真的不確定從這里還能去哪里。 我將不勝感激任何幫助。 謝謝。

Answer 1

您應該在代碼中指定此代碼：

require 'ffaker'

Answer 2

另外，請確保您在正確的gem組中有更偏愛的人。 我當時正在建立一個暫存環境，並希望加載虛擬數據，而忘了ffaker只在開發和測試環境組中。

Answer 3

我用的是git的URL添加ffaker在我的Gemfile。 我刪除了該URL，再次運行bundle，一切正常。

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