每当我使用 `npm start` 启动我的应用程序时，它都会将我带到 Rails 主屏幕上的 Ruby 而不是我的 index.html 文件

Question

I am new to software development, but I know how to use React/Redux very well, as well as Ruby-On-Rails . I am trying to have a React Frontend powered by a Rails backend. I understand conceptually how Node.js works, but not exactly the minutia. My app worked perfectly in the beginning stages before I committed any migrations, thus during testing I did not ever run rails s. Now, whenever I do, as soon as I run npm start it brings me to the rails homepage and nowhere in any of the code I've created. I've created apps before and never ran into this problem, and I know enough to surmise that the issue probably lies in the packagae.json file inside the src directory, but other than that I have no idea what to do and no errors to even google. I don't even know what files or code I should be showing... regardless, here is my packagae.json file as my index.js file

package.json
