Hey @Motarbio

From the output it looks like PlatformIO is identifying conflict between libraries.

Can you try updating platformio.ini file and changing lines Line 29 and Line 30 (https://github.com/SasaKaranovic/DIY-Filament-Dryer/blob/master/Firmware/platformio/platformio.ini#L29-L30) to be as follows

    https://github.com/me-no-dev/ESPAsyncWebServer.git
    https://github.com/me-no-dev/AsyncTCP.git

[Motarbio]

Hi Now the error is please install  git client

[SasaKaranovic]

@Motarbio Can you try doing that? You can install a Git client from https://git-scm.com/download/win (assuming you use Windows)

[Motarbio]

Done, nothing same error

[SasaKaranovic]

Please try restarting your computer after installing Git client and then try again.

p.s. When you reply via email, it messes up the formatting on the GitHub issue.

pc restarted, same error Library Manager: Installing git+https://github.com/me-no-dev/ESPAsyncWebServer.git UserSideException: Please install Git client from https://git-scm.com/downloads

Hi there, downloaded manually the libraries, compiled succesfully but with 2 warnings

Library Manager: Installing ESPAsyncWebServer-master Warning! Could not find the package with 'ESPAsyncWebServer-master' requirements for your system 'windows_amd64' Library Manager: Installing AsyncTCP-master Warning! Could not find the package with 'AsyncTCP-master' requirements for your system 'windows_amd64'

[SasaKaranovic]

You should double check if git is in your system PATH variable. Then PlatformIO should be able to pull those libraries for you automatically.
