No files matching 'path/to/app/src/.' were found.

Describe the bug

I have recently installed a new project with npx create-react-app my-app and tried to run it with npm start my-app. There is an empty space in the path, in example:

'C:/some folder/my-app'
        ^

I receive a message:

Failed to compile
No files matching 'C:/some folder/my-app/src/.' were found.

If i use a path without empty spaces for my app, everything works fine. Is important to note that this error started yesterday.

Which terms did you search for in User Guide?

I searched in the recent issues, but not found anything relevant. This problem started to happen yesterday, so I think it has to do with the new version, the previous one works fine.

Environment

The problem persist in Ubuntu and Windows, I tested in both. npm 6.14.5 node 12.18.2

Steps to reproduce

1. $mkdir ‘./my project/app’
2. $cd ‘my project/app’
3. $npx create-react-app my-app
4. $cd my-app
5. $npm run start

Expected behavior

New browser window opens with the React logo.

Actual behavior

Failed to compile

No files matching 'C:/my project/app/src/.' were found.

This error occurred during the build time and cannot be dismissed.

Check to ensure your ENTIRE absolute path to your project has no spaces or non-standard metacharacters in it…or move/re-create the project to a folder that complies. The main dropbox folder is a common culprit for spaces and parentheses. This is absolutely a bug and should be fixed.

I found that if you Ctrl + C in the terminal and do npm start again, this error does not show again.

Tried it many times didnt work for me
