ERROR in compiler_1.StaticSymbolCache is not a constructor
webpack: Failed to compile.

This problem started after I had to upgrade node from 4.5 to 6.9.5. And then upgraded angular-cli from beta 16 to beta 31.

It has been raised at https://github.com/angular/angular-cli/issues/4464 but not currently assigned and nothing happening.

Is anyone else having this problem?

So I possibly fixed it.

I created a new project and used the package.json file values in the existing project's json file.

Then I removed node_modules and dist folders, rerun npm install --save-dev @angular/cli@latest and npm install

and now ng serve works.
