After updating various packages with npm install --save <package-from-package.json>@latest, our UI-project in React can no longer be started (in developer mode in Visual Studio Professional 2017). The frontend error message is:
bootstrap:83 Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js):
TypeError: Cannot read property 'bindings' of null
at Scope.moveBindingTo (C:\myProject\node_modules\@babel\traverse\lib\scope\index.js:860:13)
at BlockScoping.updateScopeInfo
I did some research (on Stackoverflow), and the suggestion is to change stuff within .babelrc which was up to now empty, so I suppose that cannot be the thing to do. What does the error message tell me?
