What is the difference between require_relative and require in Ruby?

推荐答案

只需查看

require_relative通过允许您加载相对于包含require_relative语句的文件的文件来对内置方法require进行补充.

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

例如，如果您在"test"目录中有单元测试类，并且在"test/data"目录中有它们的数据，那么在测试用例中可以使用如下代码:

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1"
