Platform-io home doesn't work in Atom (ImportError: cannot import name DependencyWarning)

It seems that you have a deprecated Python 2.7.6 in a system.

  1. Please uninstall ALL Pythons < 2.7.9. Minimum supported version is 2.7.9 for Windows
  2. Close IDE
  3. Remove %HOME_DIR%/.platformio/penv and %HOME_DIR%/.platformio/python2 folders if they exist.
  4. Start IDE.

All should work.
