yarn start doesn't work anymore?

See original GitHub issue

Does yarn start still work for other devs? I get the following error:

Out of habit, I tried npm install and npm start and this actually worked fine. So perhaps I’m just using Yarn incorrectly? yarn --version reports 2.2.0. (I do wonder whether it’s still worth sticking with Yarn, given the many improvements to NPM in recent years.)

I could reproduce the issue on my Windows machine, however I cannot pinpoint the source of the issue. It seems like webpack or webpack-dev-server issue and I’ve opened https://github.com/webpack/webpack-dev-server/issues/3235.

As reported in https://github.com/webpack/webpack-dev-server/issues/3235, this was fixed in a recent update to webpack. I confirmed that I no longer have issues with KaTeX’s master branch.
