postcss-svgo: TypeError: Cannot set property 'multipassCount' of undefined (Gatsby)

my project is solved, use npm install [email protected] -E, detail see: https://github.com/svg/svgo/issues/1174

"resolutions": { "svgo": "1.3.0" }

Add the above to your "package.json" and then rm -rf node_modules to remove "node_modules" and then reinstall "node_modules" again.

This will resolve issue. This issue is related to latest version of postcss-svgo.
