当我在生产模式下运行我的Rails应用程序时出现以下错误,但是当我在开发模式下运行我的应用程序时它工作正常.
我可以在生产模式下使用任何宝石吗？

解决方法
您的app / controllers目录中有一个测试quarterly_export_statement_test.rb.
在生产中,Rails急切地加载所有类,因此它会尝试加载您的测试.您的测试确实需要’test_helper’.包含test_helper的测试目录不在生产环境的加载路径中(好！),因此require失败.
要解决此问题,请将测试移动到它所属的测试目录,该目录似乎是/ home / nyros / Documents / Projects / DFL / Working / DFL / test.
