Platformio currently only supports python 2.7 not 3.0. This leads to issues when having both python2 and python3 installed.

I ran into the following error:

Installing platformio...
Collecting platformio
  Downloading platformio-3.5.0.tar.gz (91kB)
    100% |████████████████████████████████| 92kB 2.5MB/s 
    Complete output from command python setup.py egg_info:
    PlatformIO Core v3.5.0 does not run under Python version 3.6.4.
    Minimum supported version is 2.7, please upgrade Python.
    Python 3 is not yet supported.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-8vfq5sgq/platformio/

Is there a way to make this work universally?

Why wouldn't this work? In my experience, pip aliases itself to pip2.7 when installing, so this would only fail if you don't have pip installed. Am I wrong?

Also, a way to avoid needing sudo for this is to attempt a user installation with --user. You'll need to refer to the full path as the directory might not be in the user's path afterwards, but that might be acceptable and it's cleaner than installing system-wide.

I fixed this locally by creating a virtualenv, but this means I had to remove the --user from pip install platformio --user. imho if you're going to run this outside of docker you should use a virtualenv.
