Eclipse IDE - No module named serial

[glamperd]

It looks like esptool runs under Python 3 in recent versions. It's working for me, although I did initially have the 'No module named serial' problem.
My config is:
- In make menuconfig, the python command is simply 'python'
- In Eclipse, set the PATH to point to the Python3.5 environment.
- Make sure pyserial is installed for Python 3.5. This happens when you run setup.py in esptool. From the esptool readme:

esptool.py depends on [pySerial](https://github.com/pyserial/pyserial#readme) version 2.5 or newer for serial communication with the target device.

If you choose to install esptool.py system-wide by running `python setup.py install`, then this will be taken care of automatically.

Glad to hear you got this working. esptool supports Python 2 & 3, however the other Python tools integrated into IDF (which are used for partition table generation, etc.) only support Python 2 at the moment. So you may still get some odd build errors if Eclipse is using Python 3 rather than 2.

If you installed IDF with a Python 2 environment, then you should be able to redirect the Eclipse PATH to use this environment instead.

Hi,

Code: Select all

#> python -V

Python 3.9.0

Code: Select all

#> pip3 install virtualenv 
#> mkdir ~/venv_arduino
#> cd $_ 
#> virtualenv .
#> source ./bin/activate
#> vim ~/Library/Arduino15/packages/esp32/hardware/esp32/1.0.4/tools/esptool.py

Change:

Code: Select all

#!/usr/bin/env python

to

Code: Select all

#!/usr/bin/env python3

Code: Select all

#> pip install serial

Install arduino-cli: https://github.com/arduino/arduino-cli/releases unzip and copy to /usr/local/bin/andruino-cli
Go to your sketch folder:

Code: Select all

#> cd ~/code/adruino/esp/projektX

Compile your Code and deploy to Board:
-b is the fqbn. in this example "esp32:esp32:esp32". Change this to your Modelname

#> grep name ~/Library/Arduino15/packages/esp32/hardware/esp32/1.0.4/boards.txt
#> arduino-cli -b esp32:esp32:esp32:PSRAM=enabled,PartitionScheme=huge_app,CPUFreq=80 compile --verbose
#> arduino-cli -b esp32:esp32:esp32 upload --verbose -p /dev/tty.usbserial-A50285BI

Press the reset button on your esp32 board and have fun.
