Suggestion: Allow Python 2.7 in unsupported mode #176

Closed pitosalas closed 3 years ago

pitosalas commented 3 years ago

This may be a terrible idea, but I just updated platformIO and was kind of tripped up by needing to install Python 3.7 to allow me to simply update my teensy. If the code still works with python2.x but you don't want to support it, it would be nice, as long as feasible to allow me to take the risk and still run it on 2.x, for example with a switch "--unsupportedpython

What is your OS? Do you use PlatlformIO IDE for VSCode?

pitosalas commented 3 years ago

I'm on Ubuntu. And I am just using the command line, and in fact am struggling a little because the PlatformIO cli keeps saying I have the wrong python even though I now have installed 3.6. It's a path problem which I am sure I can solve but really all I want to do is to refresh my teensy. The command I am issuing is

$ platformio run --target upload

And I am getting:

Error: Python 3.6 or later is required for this operation. Please check a migration guide: https://docs.platformio.org/en/latest/core/migration.html#drop-support-for-python-2-and-3-5

I followed those steps and it is still giving the error message:

2-nd step. sudo apt-get install python3-venv?

then

python3 -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/master/scripts/get-platformio.py)"

Thanks, I got it to work. Unfortunate that they decided to de-support python2.7 because I think many in the ROS robotics work are on that!
