LoadError：无法加载此类文件--ffaker

Question

请原谅我的无知。我有问题在heroku上搜索我的数据库。我跑的时候：

heroku run rake db:migrate

我得到了

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

我尝试过heroku rake db:migrate > no such file to load -- faker的解决方案但没有运气。我真的不确定从这里可以去哪里。我非常感谢任何帮助。感谢。

Answer 1

您应该在代码中指定：

require 'ffaker'

Answer 2

此外，请确保您在正确的宝石组中有ffaker。我正在设置一个临时环境，并且想要加载虚拟数据，忘记了ffaker只在开发和测试环境组中。

Answer 3

我正在使用git URL在我的Gemfile中添加ffaker。我删除了该URL，再次运行bundle，现在一切正常。

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