[Fixed]-Django 1.10 path is on mount 'C:', start on mount 'D:'

You are running makemigrations from another drive (not from C: where django is installed).

There was a bug with makemigrations on Windows:

• see this Django ticket,
• and the commit that fixed the bug:
  makemigrations crash when creating migrations on a separate drive than where Django is installed

So to fix this error you should:

• move your Django project (your Python code) on C: drive
• or update your Django version (to Django 1.11)
