Can't compile – no such file or directory

Mac OS 10.11.6
ESP32-Cam MB
At the last line in the compiling window is the following message.

fork/exec /Users/*******/Documents/Arduino/hardware/espressif/esp32/tools/esptool/esptool: no such file or directory
Error compiling for board AI Thinker ESP32-CAM.

It is correct that there is no such directory or file. Under esp32/tools there is only esptool.py, the script file

I tried putting it in a folder called esptools but no effect.

I'm new at this so have no more ideas.
Anyone else?

Uninstall/re-install with board manager or make sure to run tools/get.py if using git to clone the repo.

I'm out of ideas...
