I have installed all required libraries using npm install
and I also done npm install --save react-router-dom@4.0.0
but I am still getting this error.
My Package.json

You need React in your package.json
Try the following in the folder where your package.json
is placed:
npm install react --save
If react
is already present in your package.json
verify that the version is higher then 15.0.
If that's not fixing your error, please provide us your package.json

With the help of @rieckpil, I have followed following steps and it fixed my problem.
1: On this page I collected latest version for all following libraries react, react-dom, react-redux, react-router, react-router-dom, redux and replaced it in my package.json
file.
2: Run npm install
3: Run npm start
. If getting errors like above, simply restart you computer and run npm start
again.
