ESP32 Forum

Hi,

I am trying to run the esp-rainmaker examples on a esp32s2 soala dev kit and running into lots of issues getting setup.

I got all the tools installed and found 4.1 doesn't support esp32s2 only esp32s2beta. So following the instructions from https://docs.espressif.com/projects/esp ... et-esp-idf

I have downloaded and installed all the software however when i run install.bat from the master branch repo it fails because i don't have zlib.

Error i get below:

Could this be an issue with python 3.8?

Hi markirwin,

this is very weird and a haven't seen an error like this. Have you installed your Python from Windows Store? If yes then please download one from python.org. The interpreter from Windows Store have many known issues. I recommend to install version 3.7 or 3.8 and not 3.9.

I'm sorry for the inconvenience. We are working right now on a new improved version of the installer.

finally figured it out, i had python 2.7, 3.8 installed so removed them both and started again.. but could still run python. at cmd but not pip, i found I have another dev environment on the system path for a FOMU dev board and there tools has python.

Made some edits then reinstalled Python 3.7 and now it builds.
