Missing peer dependencies

I am new to npm and angular projects, and I am using bootstrap@4.1.1 in my package.json. When I do npm install, I get the following error - 

bootstrap@4.1.1 requires a peer of jquery@1.9.1 - 3 but none is installed. You must install peer dependencies yourself.

Does this mean that I need to add jquery@1.9.1 - 3 to my package.json under peerDependencies section, apart from installing it locally with no-save option?

Also, do we need to install this missing peer dependency on the build server as well? Or can it be ignored?

Solution

  • Simply install the dependency yourself:

    npm install jquery@1.9.1 --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.
