    text
    copied!<p>I asked a similar question prior but i finally got further along in solving it, but now i am stuck.</p> <p>I am running python on a webserver on dreamhost. I shell into it using putty and run my python script and it works great. But when i run it from php using exec, it crashes.</p> <p>Using the passthru() function in php i get returned with this error:</p> <pre><code>Traceback (most recent call last): File "newwork.py", line 20, in api=lastfm.Api(api_key) File "lastfm/api.py", line 22, in __init__ File "lastfm/filecache.py", line 19, in __init__ File "lastfm/filecache.py", line 76, in _InitializeRootDirectory File "lastfm/filecache.py", line 70, in _GetTmpCachePath File "lastfm/filecache.py", line 66, in _GetUsername OSError: [Errno 22] Invalid argument </code></pre> <p>i have no clue what that means or where i should start. for more info i am using the python lastfm module found here: <a href="http://code.google.com/p/python-lastfm/" rel="nofollow">http://code.google.com/p/python-lastfm/</a></p> <p>and my python script simply does this:</p> <pre><code>import sys import lastfm import MySQLdb sys.stderr=sys.stdout value="testuser" api_key='---my api key is here' api=lastfm.Api(api_key) user=api.getUser(value) top_artists=user.topArtists </code></pre> <p>any help would be greatly appreciated, or any ideas whatsoever. I dont even know where to start.</p> <p>Edit: i did a little more work and found the full last line is:</p> <pre><code>line 66, in _GetUsername os.getlogin() or \ OSError: [Errno 22] Invalid argument </code></pre> <p>and the GetUsername function simply is this:</p> <pre><code>def _GetUsername(self): '''Attempt to find the username in a cross-platform fashion.''' return os.getenv('USER') or \ os.getenv('LOGNAME') or \ os.getenv('USERNAME') or \ os.getlogin() or \ 'nobody' </code></pre> <p>with indentation corrected not here.</p>
