Changing the path for wkhtmltopdf


I am using ERPNext on Bitnami/Mac Sierra. And I’m getting messages like

The resource you are looking for is not available

I’ve installed wkhtmltopdf and wkhtmltoimage on /usr/bin (SIP disabled)

and still it doesn’t work.

If I would like to change the PATH of wkhtmltopdf, to the ERPNext at Bitnami directory, what parameter I should change?

Copy to /usr/local/bin and make executable.
