To Reproduce

idf.py menuconfig

Expected behaviour

There is only one qrcode at https://components.espressif.com/components/espressif/qrcode
It should just download it and continue building.

@Panometric thank you for the issue,

I've just tried, but didn't manage to reproduce your problem.
Could you please provide more details?
Do you have EXTRA_COMPONENT_DIRS configured in your project? Could you please share the content of your main/idf_component.yml?

Could you please also try to reproduce the problem on an empty project by running:

idf.py create-project tstqrcode
cd tstqrcode
idf.py add-dependency qrcode
idf.py reconfigure

@kumekay Thanks for the quick reply. I agree, your tstqrcode project works fine.

My EXTRA_COMPONENT_DIRS is set in CMakeLists.txt. And that appears to be a problem.

set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/qrcode)

My file is simply this:

dependencies:
  qrcode: "^0.1.0"
  ## Required IDF version
  idf:
    version: ">=4.1.0"

I added the idf_component.yml because the example would not compile, the qrcode was missing.

I can see why I should not define it twice, but it's an easy mistake to make and the error did not lead me to understand where it was coming from.
