Ubuntu: exec: "python": executable file not found in $PATH

I normally use ESP-IDF on Windows, but also installed ESP-IDF on Ubuntu and was able to compile and flash the board.

Then I installed Arduino from "Ubuntu Software", then used the boards manager with additional boards manager URL and obtained the ESP32 boards.

When compiling an example, I see "exec: "python": executable file not found in $PATH"

I can type python from a terminal and it runs. Adding /usr/bin/python to $PATH in profile.d (similar to adding paths for installing ESP-IDF) makes no difference.

Installing from running install.sh from the downloaded tar works for anyone else with the same problem.

Hi, I've been having the same issue. What "install.sh" file are you running? And which tar file are you pulling it from?

I just figured out where the "install.h" file is. For those who come across this in the future:

The "install.h" referenced in this post is from the Arduino IDE folder. If you're on Ubuntu re-download the Arduino IDE from their website (https://www.arduino.cc/en/Main/Software) and then once you have extracted the folder to where you would like the IDE, run the "install.sh". All this command does is create an application for Ubuntu.

I found out that I was having issues with python not being included in the $PATH when I was using the Arduino IDE from the Ubuntu Software Store.

I am having this same problem. I have tried the remedies above with no luck.

Cannot get away from:

Code: Select all

exec: "python": executable file not found in $PATH
Error compiling for board TTGO LoRa32-OLED V1.
What else could I try?

Thanks.

P.S.: It was the pySerial thing again. Thought that I had installed it on this laptop.

This was the solution for me. You have to install python if have not install it.

sudo apt install python

Hi all,

I know the post is a bit old, but I just ran into the issue. Since *ubuntu 20.04, you just need to install the package python-is-python3 in order to have the python command to execute python3 by default.

I also had to install python3-serial to have arduino working.

PE.

CONFIRMED: 26 Aug 2020

In order to support the ESP32, you will need to install the following packages:

Code: Select all

  sudo apt update && sudo apt upgrade -y \
    python-is-python3 \
    python3-serial
The Arduino IDE MUST NOT be installed as a .deb or .flatpak. Instead, it must be installed from the .zip file downloaded from the Arduino downloads page (https://www.arduino.cc/en/Main/Software).
