Merging/yarn installing didn't produce working build process #23461
Description
What's the issue?
Merging the latest master on a fairly outdated branch and running yarn install still produced a failing gulp run.
Issue was fixed by blowing away node_modules and re-yarn installing.
I also had to gulp clean to solve a different issue that occurred later in the build.
Error: @babel/plugin-proposal-dynamic-import depends on a modules
transform plugin. Supported plugins are:
- @babel/plugin-transform-modules-commonjs ^7.4.0
- @babel/plugin-transform-modules-amd ^7.4.0
- @babel/plugin-transform-modules-systemjs ^7.4.0
If you are using Webpack or Rollup and thus don't want
Babel to transpile your imports and exports, you can use
the @babel/plugin-syntax-dynamic-import plugin and let your
bundler handle dynamic imports.

How do we reproduce the issue?
Probably not easily reproduceable - have a really old branch and then merge the latest code? :)
