Exception: it seems 'yarn' is not installed/available on your system:

[modmt]

Hallo all,
I have a problem compiling the .bin for WT32-ETH01 to update my old firmware from last year. In Visual Studio Code I get an error that yarn is missing. But yarn is installed on the computer. By entering yarn -v i get the version 4.4.1. Also the right folder is added to the system nvironment variables (PATH). Ich checked it on two computers, but always got the same error.
When i compiled the old firmware mid 2023 i had no problems with it.

Does someone has an idea what could be the problem?
Unfortunately there is no precompiled firmware that I can use on github for the WT32-ETH01, so there is no way around to compile.

Thank you.

Did you check the installation and compiling documentation ?
Especially are you able to find yarn -v inside the PlatformIO Terminal / Shell Environment ?

Hello Stefan,
thank you for the fast reply.
Yes, I checked the documentation and did it like described there. Also the build of the webApp seems to work (?).
I also can find yarn -v inside the PlatformIO Terminal or the shell environment (s. Screenshot).

Only the compiliation does not work.

Due to the fact that this issue is related to OpenDTU-OnBattery and does not apply do OpenDTU itself I would suggest that you ask this question there.

I'm sorry, I posted in the wrong group :-( Had too much windows opened and accidentally choosed the wrong page.
I tested OpenDTU also. Compared to OpenDTU-on-Battery compiling worked fine here.

I will post my problem in the right group. Sorry again.
