Unable to install library after 6.0.1 update from Github

Hi everyone!

I have an issue with my project https://github.com/stscde/modbus-esp8266-solaredge after updating to platformio 6.0.1. The issue also persists after updating to 6.0.2b1. I am on Windows 10.

The following output shows the issue when I try to install the project as a library. I use the following library in platformio.ini and library.json (see below) https://github.com/emelianov/modbus-esp8266.git. When the PlatformIO library manager downloads the library it seems not be able to extract the https protocol correctly. Instead it adds some kind of library path or name in the protocol parameter.

I already checked the latest docs for lib_deps and “dependencies”. Seems my settings match the docs.

Any help is appreciated.

Best wishes

Interesting, not reproducable for me with Windows 10 + git 2.34.1.

>pio pkg install -g  -l https://github.com/stscde/modbus-esp8266-solaredge.git

Can you try to remove the .pio of the project and do another pio upgrade --dev, then try the command again?

Hi Max,

thank you for your really fast feedback. Got it working thanks to your input :slight_smile:

  • updated to git 2.36.1 64 bit
  • deleted .pio folder
  • pio upgrade --dev

After these steps clone+compilation was working again.

Thank you very much and have a nice weekend
