Dtella Errors

ImportError: No module named dns.resolver

Problem Description:

This occurs primarily in *nix environments, or when you try to run the Python source instead of the executable. Usually Python gives you a traceback that ends with "import dns.resolver".

Solution:

You need the python-dnspython package. In Debian or Ubuntu, "sudo apt-get install python-dnspython" will fix it. Not using an apt-style repository? Look for a similarly-named package for your OS. I can't think of a distro that lacks the Python dns library. If you happen to use such a distro, you can get the source code from http://www.dnspython.org/ and compile it yourself.

ImportError: No module named twisted.python.runtime

Problem Description:

This occurs primarily in *nix environments, or when you try to run the Python source instead of the executable. Usually Python gives you a traceback that goes dtella.py->dtella_core->dtella_fixtwistedtime->import twisted.python.runtime.

Solution:

Like the previous error, you need to add a python package. This time, it's the python-twisted packages. In Debian or Ubuntu, "sudo apt-get install python-twisted" will fix it. Not using an apt-style repository? Look for a similarly-named package for your OS. If you can't get a package, you can get the source code (and Windows installer) from http://twistedmatrix.com/trac/.

ImportError: No module named Crypto.Cypher

Problem Description:

Another problem that comes from running the Python source. The traceback goes dtella->dtella_core->dtella_crypto->"from Crypto.Cypher import AES".

Solution

Add another Python module. I can't find the source or webpage for this one, but "sudo apt-get install python-crypto" solved it (Debian/Ubuntu).
