Missing “react-dom.production.min.js” file

[EFanZh]

I was using a fresh installation of Jupyter Notebook 6.0.0. After opening the web page, the console shows the following error message:

http://localhost:8888/static/components/react/react-dom.production.min.js net::ERR_ABORTED 404 (Not Found)

Thanks for the report, fixed by #4772.

[meetri]

is there a work around for this until 6.0.1 is released?

[hss14]

I encountered the same issue. Anyone know a work around?

workaround: #4772 (comment)

TypeError: undefined is not an object (evaluating 'U.unstable_cancelCallback')\

After attempting the workaround, I'm having the same problem as sunsan05 above.

What I really cannot understand is how the hell this happened to my machine without me upgrading Jupyter. Ten minutes ago Jupyter was working fine and has been all morning, now it is broken, and I cannot get work done. Is Jupyter auto-upgrading my notebook server without asking me?

@sunsan05

I think the problem is a mismatch between the linked react-dom.production.min.js and the react.production.min.js. The first is v16.9 while the one already in Jupyter is v16.0

I found a version of react-dom.production in v16.0 here: https://gist.github.com/aweary/92db2b795b85fe29d096aca2c57cd3ec#file-react-dom-production-js

It is not minified. So when you copy it to the directory you'll have to change the name to react-dom.production.min.js or minify it yourself.

I'm now back up and running, but I would like to know from a dev who understands the internals of jupyter how I wasn't having this problem twenty minutes ago (and have been using Jupyter all morning with the ipywidgets I developed) and suddenly this problem crops up without me updating anything on the jupyter end.

I'm getting the same issue.

[W 21:27:55.214 NotebookApp] 404 GET /static/components/react/react-dom.production.min.js (192.168.9.1) 14.07ms referer=http://192.168.9.4:8888/tree?token=6f406c28c3753e2ebf7b383ffeabacd1f5dbcf5e98bb5670

I'm running Jupyter on a server at 192.168.9.4. My laptop that I'm browsing from is at 192.168.9.1. Maybe there's a CORS issue happening here? Would love to see this fixed.

Could you please try to update to Release 6.0.1 and let us know if you can still reproduce the issue.

Using this command "import site; print(site.getsitepackages())", you can find where the "site-package" folder is (site-packages\notebook\static\components\react). Then you know where to save the file "react-dom.production.min.js".
