create-next-app fails with error Command failed with exit code 1.

[pkail]

I typed create-next-app into the terminal. When it had downloaded everything, I typed yarn dev as described here: https://nextjs.org/docs/getting-started
I also tried the 'manual install' several times. I deleted the entire directory in between each attempt.

Additional context

It's got something to do with not being able to find autoprefixer.

Couldn't someone have tested it before putting it online? I have lost all faith in next.js.

Add any other context about the problem here.

There are errors going back to 2018 with autoprefixer. It doesn't work properly in any of the tutorial videos on YouTube. I have tried looking at various solutions on SE, but everything is for much older versions, and doesn't seem to work even for them.

[timneutkens]

Looks like you have a global postcss.config.js:

/home/p/Data/WS/postcss.config.js

Which imports a module that you don't have installed. Probably you didn't intent to have a postcss configuration file in your home directory so I'd recommend deleting the file.

The getting started guide works fine and we have extensive integration tests to ensure Next.js doesn't break between versions.

[pkail]

It does work without the config file. But Next put it there, not me.

[timneutkens]

A postcss.config.js file is not created by Next.js, it's only read for configuration.

[pkail]

That's a mystery.

Anyway, thanks for your help.
