Steps to reproduce:

git clone https://github.com/reactjs/reactjs.org.git
cd reactjs.org
yarn
yarn dev
open http://localhost:8000 in chrome



edit: don't know if related, but in #1065 I see changes to error-decoder.html.js of fields { path { id } }

edit2:
I am assuming everything in the readme works for windows as it doesn't say otherwise.

Also, when it says "Node: install version 8.4 or greater" in the readme, does that mean 8.x.x? Inside the package.json, I see:

"engines": {
    "node": "^8.4.0",
    "yarn": "^1.3.2"
  },

what does that mean for my globally installed node and yarn programs? And should the readme be updated to reflect the contents of the package.json?

Hi!
I reproduced your steps and got no errors on console.

I used the following:

• OS: Windows 10
• Node 8.11.3
• Yarn 1.9.2

Also, to see those "engines" on package.json means that, If you have a version lower than Node 8.4.0 or Yarn 1.3.2, it won't work properly or, at some case, won't work at all if you don't have those or major versions installed.

I attach an image of the console output after running the command yarn dev

Maybe updating to the newest versions of Node and Yarn and re-reproducing the scenario will make it work.

Also having the same issue here but on windows 8 pro

OS: Windows 8 pro
Node: 8.11.3
Yarn: 1.9.2
->yarn versions

->yarn dev

-> IN Browser

[th7nder]

Having a similiar issue.
OS: Windows 10
Node: v8.11.4
Yarn: 1.10.1

Also localhost:8000 is blank, and errors like this pop up.

I had something like this a few times.

Removing .cache directory in the project root, removing node_modules and re-running Yarn solved it.

[AlmeroSteyn]

Having the same issue as above.

OS: Windows 10
Node: v8.11.2
Yarn: 1.10.1

Deleting .cache and node-modules did not work.

Did a clean git clone from master and then I first had the first error in this issue. After cleaning I got the second again.

[gaearon]

Now Netlify builds have the same issue.
I have no idea what it means.

[th7nder]

Got the same issue as @killynathan on Linux (Ubuntu 18.04).
I've had Node 8.10.0, tried removing .cache and node_modules and the same thing happened.
Then installed NVM, used node lts/carbon (8.12.0), removed .cache and node_modules and it started to work.

[DSchau]

Whoa, fun. @th7nder the Node 8.10.0 comment was a helpful one. I am able to semi-reliably reproduce the issue now once I'm using that. I'll take a look at this and report back.

Although the failing Netlify build is using v8.12.0, it seems like it's something in Node 8 at least.

[DSchau]

Also @th7nder the issue I solved is slightly different than the issue you ran into. If you run into that again, please open a new issue! Thank you!
