git clone https://github.com/facebookincubator/create-react-app.git
cd create-react-app/packages/react-dev-utils
yarn
yarn link

cd my_app
yarn link "react-dev-utils"
yarn start

will be fixed in the next Facebook create-react-app release, we just rebased on their latest code.

I have unpublished 2.9.0. Mistakenly I published the incorrect version on the facebook code. I will now republish 2.10.0 with the last publish from facebook 51ee648f2517d6e86ba8bcffdf9144ef8954b19e.

Thanks everybody - help in real-time. Impressive!

@wmonk Has 2.10.0 been published ?

[rnemec]

I believe the dependency react-dev-utils has not been published with the latest code yet, by the facebook team. So the rebase from CRA needs to be carefully selected. Right now, it's either wait for @wmonk to be comfortable what he is merging, or go with the @bootstraponline suggestion (link).

@bootstraponline , if you can rewrite your solution using npm only, some folks may appreciate it, I'd guess. It's no big deal, those who cannot do that by themselves, maybe should not use the link approach. 😉

[quantuminformation]

@changLiuUNSW 2.8 is still the publish version

facebook/create-react-app@36cd35d#diff-0ed7fc71b70cf1d8c98f8fcabdd35f17 is the commit.

I think it's easier to wait for FB to publish a new https://www.npmjs.com/package/react-dev-utils before releasing create-react-app-typescript Ideally we'd have a small diff from upstream so creating another custom patch would increase the maintenance burden.

[wmonk]

Closing this, as it's no longer an error. Wainting to integrate latest fb changes again.
