sh: react-scripts-start: command not found - node.js

Question

I have a project that I cannot run npm start on.
I haven't touched this project in two weeks. The only thing I did yesterday was add a git repository, that's it.
When I tried to run npm start I got this error:
sh: react-scripts-start: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! bk-react-replica#0.1.0 start: 'react-scripts-start'
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the bk-react-replica#0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
I've looked at the solutions on other posts about this same error but none work for me. I've deleted the node_modules directory and package-lock.json files, then ran npm install.
However, I still get the same error message. Does anyone know what's wrong?
This is my package.json file:
{
"name": "bk-react-replica",
"version": "0.1.0",
"private": true,
"homepage": "http://qhafeezdomain.dreamhosters.com/projects/bkreplica",
"dependencies": {

},
"scripts": {

}
}

As I will reference you to an answer I provided to a question similar to yours, run this:
npm i -g npm //which will update npm
rm -rf node_modules/ && npm cache clean // to remove the existing modules and clean the cache.
npm install //to re-install the project dependencies.
Edited:
I just noticed your package.json it should be:
"scripts": {
"start": "react-scripts start",
not
"scripts": {
"start": "react-scripts-start",
