Another issue installing ESP32 toolchain

chico · Post by **chico** » Fri Aug 18, 2023 8:07 pm

Hi - Long-time FC user here who's finally taking a closer look at v10...

I'm sure there's a fairly easy fix for this, but I haven't been able to make anything I've found in the forums work for me.

I'm attempting to install the ESP32 toolchain. I followed exactly the clear instructions posted here: https://www.flowcode.co.uk/wiki/index.p ... _Toolchain

The install seems to have gone well, but when I attempt to compile a simple blink project it appears that esp-ide is trying to use Python 2.7 instead of the Python 3 it installed in the installation process.

From the compilation output:

I'm thinking this is an environment or path or esp-idf setup issue, but I'm not sure how to fix it. I provide more verbose output information below. I'm hoping this a commonly seen issue and there's a simple fix (fingers crossed

)

Thanks in advance...

Presumably your PATH environment variable is pointing at the older v2.7 Python installation. You could try manually editing the PATH (Windows Settings...System...Advanced System Settings...Advanced...Environment Variables) so it points at the 3.7 installation instead.

Thanks for the response. Your suggestion solved the problem, although there was an intermediate step which I'll document here in case it might help someone else.

The various installers had done their job, but had left the path pointing to "\Python 3.7\Python.exe" instead of just the folder "\Python 3.7". This caused the compiling process to use Python 2.7 instead of Python 3.7.

Here are the screen shots of what did NOT work correctly:

That setup caused the esp32 compiler to access Python 2.7:

The fix was to change the environment variable from "\Python 3.7\Python.exe" to just the folder "\Python 3.7".

Thanks for the assistance...
