I'm new to using npm and react inside Visual Studio. Tried to install Material-UI@next for my React project but got these warnings when running the project.

enter image description here

Something obvious I am missing?

  • Are you using an AMD module loader (i.e. CommonJS or RequireJS)?... Commented Oct 17, 2017 at 19:51
  • No, I don't think so. I am using webpack to pack the js-files. The project is based on the Visual Studio template "React.js and Redux", and the only change I've made so far is adding Material-UI. Commented Oct 17, 2017 at 20:07
  • what version of visual studio? Commented Oct 17, 2017 at 20:23

I had the exact same issue getting the latest Material-UI working with .Net core's 'react/redux' template. I found it to be a matter of getting the correct versions of the dependencies in order.

In order to get it working, I updated all of the packages to the latest versions:

$ npm install -g npm-check-updates $ npm-check-updates -u $ npm install

Once I updated those refs, some of the sample code broke. So I simply removed the broken bits as all I cared about was getting Material-UI working.

Once I had that part, I just had to do the proper imports and was able to use the Paper element.

Here is an example of how I got it working.

Good Luck!

Edit: I've updated the repo and fixed any version issues I found. I'm going to try and keep this repo updated as best I can. Cheers!
