does it still happen after running npm i -D preact-cli@rc in the project and then npm run dev?

[mkrl]

does it still happen after running npm i -D preact-cli@rc in the project and then npm run dev?

Unfortunately, it still fails, I'm experiencing the same problem. Tried both @latest and @rc preact-cli to initially set the project up, as well as updating to @rc within the project.

5.3.0-61-generic #55~18.04.1-Ubuntu Linux
node -v 10.17.0
npm -v 6.11.3

[ForsakenHarmony]

It should be fixed with the latest rc

[mkrl]

It should be fixed with the latest rc

Can confirm it was fixed for me in rc 18. Thanks!

[rmtsrc]

This is now working correctly for me, thanks 👍
