[dasarishiv]

its mentioned that version 4.1.0 is updated for React 16. but its package.json have dependency : "react": "^15.6.1",
"react-dom": "^15.6.1",

which cause multiple node_module installation dependency error:

I have been getting the same issue when using the navbar example from the docs.

I am getting the same issue here for the nav bar, so I uninstall React 16.0 version and install 15.6.1 version react and react-dom instead

Hello,
We've updated our product to the latest React version. Please delete mdbreact from package.json and then add to dependencies this line:

"mdbreact":"git+https://github.com/mdbootstrap/React-Bootstrap-with-Material-Design.git#react-upgrade"

We'll update it also in npm with the next release of mdbreact.

Regards

that "fix" did not work for me

What are Your errors? If console still shows same errors, it means that You haven't reinstall mdbreact properly.

[jstgermain]

I deleted the mdbreact file from node_modules and changed the package.json, did npm install and get same error. I then blew away entire node_modules, and reinstalled, same error. Docker could be messing up, so I will try to reinstall entire app today and do a build. I will keep you posted. Thanks for the quick response.

mdbreact or mdbootstrap? what I installed is the mdbootstrap package and it's the folder I see in node_modules

[jstgermain]

So the react update branch is the one installed, but no styles are loading. No more errors.
