Missing peer dependencies

Simply install the dependency yourself:

npm install [email protected] --save

Although --save is optional I recommend to put it, so the next time you simply can type only npm install and both bootstrap and jquery will be installed. You can read about peer dependencies on npm documentation.

You should read the terminal whether all important dependencies have been installed. If it hasn't install those manually.

npm install <MISSING DEPENDANCY> --save

In your case

npm install [email protected] --save
