Gatsby: Unknown browser query `dead` - WTF

[xblue-light]

I have a project using a Gatsby theme starter and last week I was building my project with no problems what so ever, this morning I tried to run a new build without having done any prior changes at all I get some intimidating error. I need to fix this this project is due to go live soon..

Error Generating CSS failed
BrowserslistError: Unknown browser query dead

FYI - Also getting this on some NEW starter Gatsby repos.

@xblue-light can you provide relevant environment information by running gatsby info --clipboard?

I also had the same issue... impossible to debug, working well on develop then crash on build.

gatsby info --clipboard gives me that :

This is a compatibility bug between gatsby-cli v2 and gatsby v1. Working on a fix which should be out later today.

[PierreBresson]

Found the problem, it's because gatsby-cli is 2.x and should be 1.x.
Fix it with : npm install --global [email protected]

Thanks for the workaround @PierreBresson 👍

This should be fixed in [email protected] and later.
