Unknown plugin "@babel/plugin-proposal-class-properties"

Hey, I am using your library with a react-native app with

"babel-cli": "6.24.0",
"react": "16.0.0",
"react-native": "^0.50.4",

And I get this error:

ReferenceError: Unknown plugin "@babel/plugin-proposal-class-properties" specified in "/home/circleci/rnapp/node_modules/prism-react-renderer/package.json" at 0, attempted to resolve relative to "/home/circleci/rnapp/node_modules/prism-react-renderer"

I also tried this this by updating babel-cli to 7.0.0 but I get the same error

Oh, that's really odd! I wasn't aware that Metro Bundler now picks up all custom babel configs for modules. Is your setup as usual? As in, the package is simply installed with npm/yarn?

If so, I'll prepare another release that splits out the babel config into a babelrc and excludes it from the published package.

Yes, I used npm to install the package
