Rails app accidentally installed in root folder

Question

I accidentally created a Rails app in my root directory. I ran the following command and got an error:

rails new test_app
Can't initialize a new Rails application within the directory of another, please change to a non-Rails directory first.

So I tried running

bundle exec rails server

and it looks like the server is listening on port 3000.

How do I remove this app from my root directory?

Answer 1

只需删除文件夹，或者您可以执行此命令

rm -rf test_app

Answer 2

Hoping you're on *nix based system.

1. Stop the running server using:

    kill -9 $(lsof -t -i :3000) 

2. Change working directory to root using:

    cd / 

   or wherever you're defining your root as.

3. Remove the accidentally created Rails application directory using:

    rm -fr rails_project_in_root_dir 

   where rails_project_in_root_dir is the Rails application directory in your root directory.

Answer 3

Okay, I'm not sure how it got installed in the root directory, but I ended up just manually deleting all the folders and files that get created when you run

rails new app

Here's where I found the list of files:

That ended up resolving the issue. Thanks for the help guys.
