Install libvips to your Heroku instance, without any other dependencies.
heroku buildpacks:add https://github.com/Verumex/heroku-buildpack-libvips
By default the buildpack will install the latest release of libvips to your
application, but you can install a specific version of libvips by setting a
variable. For example:
heroku config:set LIBVIPS_VERSION=8.7.4
The buildpack will install the latest libvips if the value of
latest or the variable is omitted.
The first time you deploy, libvips will be compiled during deployment, adding minutes to the deployment time. The installation will be cached, so subsequent deploys will not recompile unless the libvips version changes.
Copy the snippet above into CLI.
