python - pip install rauth fails : syntax error -

I just installed Python 3.3 and then by issuing the command I tried to install Ruth: < P> pip install roulette

And I get this error:

  Rouge Download / Unpacking Package Runup is running setup_apple_info for Ruth Traceback (most recent call Last): File "& lt; string & gt;", line 16, & lt; Module & gt; The file "c: \ users \ pipul \ appdata \ local \ temp \ pip-build -Pilip \ rauth \ setup.py", l 4 in, in & lt; Module & gt; Ruth imported the __version__ file from ". \ Rauth \ __ init__.py", line 30, in & lt; Module & gt; .

 Similarly installing oauth2 also fails. But installing Selenium succeeds.  
 Now what can be the reason for this failure?  
 Thanks in advance. Like many packages, Rauth currently does not support Python 3.   
 
 
 Like many packages, Rauth currently does not support Python 3. However, it seems that one branch where they are working on it. See.  
 In general, if you use Python 2.7, you may have more luck installing the package.
