Answer 1

NODE_TLS_REJECT_UNAUTHORIZED=0 npx playwright install

use this if you are trying in mac os

Answer 2

I work behind a netskope proxy. They way I got past the self signed cert in chain error is to set the NODE_EXTRA_CA_CERTS using a powershell command.

Open a powershell command window and enter the following being sure to update the file path to your cert

$Env:NODE_EXTRA_CA_CERTS="C:\certs\root.crt"
