'os.path.expanduser' func create the temp dir question

[taozywu]

• Fixed: Change 'os.path.expanduser' func to 'tempfile.gettempdir' func for create the temp dir.

• Question:
  When you install with root, the normal account will be called with the following error:

Traceback (most recent call last):
  File "/usr/bin/myqr", line 9, in <module>
    load_entry_point('MyQR==2.3.1', 'console_scripts', 'myqr')()
  File "/usr/lib/python2.7/site-packages/MyQR/terminal.py", line 34, in main
    args.directory
  File "/usr/lib/python2.7/site-packages/MyQR/myqr.py", line 92, in run
    os.makedirs(tempdir)
  File "/usr/lib64/python2.7/os.py", line 157, in makedirs
    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/root/.myqr'

• Location:
  os.path.expanduser('~')：the value i get in my Linux system is root，so i try to fix it!
  I don't know much about python, so i am not sure this is a bug!
