`require': cannot load such file — spec_helper (LoadError)

问题

I am creating

bundler gem --test=rspec MyGem.

in which I'm getting the repository structure.

When I try to run the rspec code I get the following error:

 `require': cannot load such file -- spec_helper (LoadError)

I then try to apply require relative but I still get an error:

回答1:

You're running the specs from the spec folder. This messes up the load path. Run specs from the root of your project: ~/sheetal.

rspec spec/sheetal_spec.rb

Rspec adds the spec and lib folders to the load path automatically. If you're already in the spec folder, rspec is going to add spec/spec to the load path instead.

Assuming that you have your code in the lib folder, you would have to add both . and ../lib to the load path if you want to run your tests in the spec folder.
