Open package.json, added following rules under rules line:

"rules": {
  "linebreak-style": 0,
  "global-require": 0,
  ...

for VScode users: click the option at the bottom-right of the window and set it to LF from CRLF errors will fixed for me

Against it, if you are using Windows line breaks just change your editor to use LF instead. 99% of the WP ecosystem is geared towards Linux and by allowing Windows line breaks it will just lead to issues for 98% of other developers.
