I'm trying to use esptool.py to flash ESP32. Since I use Arduino IDE I assume it is installed and work correctly. But since I need to work using command line I encounter problems regarding python2.7 which send an end of life messages, and python3.8, both installed on my mac.

I followed esptool github pages, for example:

guydvir@Guy-MacBookPro ~ % pip install esptool
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

I mostly get this warning regarding v2.7. By the way, when using a venv problem was solved, but I rather know what is wrong.

  • Is the end of life message the only problem? – mmmmmm Mar 30 '21 at 11:48
  • Typing ‘esptool’ yields an error – guyd Mar 30 '21 at 11:56
  • Since you have two Python versions, you should select the right pip when installing something - aka check/verify first paths with which pip and pip --version, and for Python very 3.x use pip3 install ... or python3 bla... to start Python 3x. Take care the command suggested on esp githhub pages is esptool.py rest-of-command. You may need to chmod +x esptool.py to allow it to be started simply esptool. – Yoan Mar 30 '21 at 12:12
  • re "Typing ‘esptool’ yields an error " what is the exact error? – mmmmmm Mar 30 '21 at 12:32
  • The same with me: Mac OS M1 Monterey 12.4 can't install esptool (with python 3.10) – Coliban Jun 10 '22 at 15:08
