I am currently trying to use create-react-app which uses three different packages: react, react-scripts and react-dom. I have installed create-react-app and then when I change into the directory and hit npm start I get a react-scripts: command not found. I've ran into a lot of problems with this. I can see react-scripts is in my node_modules folder but I keep getting command not found when trying to run npm start. I tried to delete and re-install all of my node_modules but it didn't work. Anyone else having this issue?

Firstly Delete package-lock.json file in your project folder.
And then install dependencies again by npm install. That should solve this issue.
This usually happens because of a bad npm packages installation (using npm and yarn at the same time?). It can be desperating, but if you try these steps, it should work.
1st solution:
Remove node_modules folder. At the project's root folder, run
> yarn
> yarn run start
2nd solution:
At the project's root folder, run
> yarn upgrade
> yarn
> yarn run start
Next time you want to add a dependency using create-react-app, I recommend you to use 'yarn add' instead of 'npm install'. (Source: https://github.com/facebook/create-react-app/issues/1155)
Delete the /node_modules directory and the package-lock.json file using the rm command:
rm -rf node_modules
rm -rf package-lock.json
Install react-scripts using the following command:
npm install react-scripts
Install the dependencies using the following command:
npm install
Start the local server by running the following command:
npm run start
Note: If you are a Linux user then don't forget to add the sudo command before npm.
