Error: "pybind11" must be installed before running the build.

hello team,

i tried to install GrovePi with the Detailed Directions
but the script bash ./update_grovepi.sh
does exit with an error:

"Error: "pybind11" must be installed before running the build.
error: setup script exited with 1"

i tried with the official guide for installing pybind11
but this did not help.

also i tried

• curl -kL dexterindustries.com/update_grovepi | bash
• curl -kL dexterindustries.com/update_grovepi | bash -s -- --bypass-gui-installation
  same error for both..

i am on

$ uname -a

currently i have no idea what i am doing wrong - or if it is really a incompatible os version i am using?

iam open for any tips & ideas ;-)

Start by reproducing the failure with bash ./update_grovepi.sh on the reported Raspberry Pi and Raspbian versions. Inspect update_grovepi.sh and the pybind11 installation/build output to determine why the dependency is not detected; done means the documented update command completes without the reported error.
