Install Dependencies for I/O Expander: MCP23017 (16 Channels): On/Off

[grux77]

RPi4
Linux Mycodo 5.10.60-v7l+
Mycodo Version: 8.12.6
Python Version: 3.7.3 (default, Jan 22 2021, 20:04:44) [GCC 8.3.0]

Failure:
The I/O Expander: MCP23017 cannot be added.

Reproduction:
Try adding the I/O Expander: MCP23017 in Setup/Output. There is a hint that dependencies have to be installed:
"Dependencies not installed: adafruit_mcp4728". After the installation you can still not add the MCP23017 although the log does not show any errors.

My solution was:
First install the dependencies for Digital-to-Analog Converters: MCP4728. Then the Expander MCP23017 can also be added.

Please paste the dependency log excerpt when you were prompted to install the dependency and you pressed the Install button.

[kizniche]

I'm not understanding the issue. You're showing the log of the dependency successfully installing, which is the expected behavior.

[kizniche]

Oh, I see the issue. The MCP23017 output has the MCP4728 listed as the dependency, which is the wrong dependency. I'll fix that for the next release. Thanks for the bug report.

[grux77]

That's it
