Element ref was specified as a string (node) but no owner was set.

[andreperegrinah]

I getting this error when I try to use the <MathJax.Node>

react-dom.development.js?cada:55 Uncaught Invariant Violation: Element ref was specified as a string (node) but no owner was set. This could happen for one of the following reasons:
1. You may be adding a ref to a function component
2. You may be adding a ref to a component that was not created inside a component's render method
3. You have multiple copies of React loaded
See https://fb.me/react-refs-must-have-owner for more information.

@webMasterMrBin What part of that linked issue worked for you?

[liu0fanyi]

@mjyoung I did this it was work
rm -rf node_modules/react-mathjax2/node_modules/react
this is why

[webMasterMrBin]

@mjyoung add this resolve: { alias: { 'react': path.resolve(__dirname, '../../node_modules', 'react') } } in my webpack.config.js

Why is React included as a dependency if it causes issues?

I know this thread is old but this issue is still causing problems.

This issue also makes deploying React apps to GitHub pages impossible. This really needs to be fixed. I'm using my own fork (the PR) to fix it for now.
