@dfadev Did you figure out the issue? Mind providing some insight?

[dfadev]

No. I wasn't able to repro on another machine. Are you getting the same exception?

[sailor27]

Hi, I am having the same exception when running npm start in the website directory.

I am getting the same issue. Anyone have an idea why this is?
BrowserslistError: Unknown browser query 'dead'

Are you getting this issue only with npm start? Does yarn start work? I know that yarn --cwd website start was causing an issue. I am wondering if cd website; yarn start works?

[twhite96]

Getting the same error. yarn start and npm start give the same error.

Updated node_modules deleted and reinstalled node_modules. Same thing happens.

There is a BroswerList object in your package.json in the main part of whatever app your docs live in. I deleted that and got it to work. Try that and see if it works for you.

Is it correct to assume that this bug only occurs if your docusaurus app lives inside another app with another package.json ? 👍

[dfadev]

@twhite96 is correct, thank you! -- I am able to repro this on multiple machines by placing the following package.json in my home directory:

{
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

Am closing this because according to Browerslist docs, it's the expected behavior to search for a browerslist key in package.json in current and parent directories.

You can resolve this error by adding a browerslist key to website/package.json.
