ReferenceError: Unknown plugin "babel-runtime-es2015-instance-methods" specified in "base" at 1

I installed through npm and added 'babel-runtime-es2015-instance-methods' to my plugin array but I am still getting this error. What am I doing wrong?

@UX-Unicorn I have not been using and maintaining this plugin for while. However I just tried using it with the latest version of Babel and I works fine. That being said you have to make sure that babel-runtime-es2015-instance-methods/call-instance-method.js is picked up by Babel because otherwise the methods will be missing.

How you ensure that this is the case totally depends on your build setup. If you provide me your configuration (.babelrc, webpack.conf.js, etc.) I will have a look at it.
