Python/Tornado error on app launch

I am repeatedly getting this error with my Tornado app on launch:

  File "/Library/Python/2.7/site-packages/tornado/database.py", line 59, in __init__
    args = dict(conv=CONVERSIONS, use_unicode=True, charset="utf8",
NameError: global name 'CONVERSIONS' is not defined

I have installed Tornado and MySQLdb with pip. I have uninstalled and re-installed both. I am running against a remote MySQL instance.

I am baffled and not sure how to troubleshoot. Any advice?

if you run it within MAC OS and Eclipse, you should add DYLD_LIBRARY_PATH into eclipse' environment setting.

Ultimately this was masking this error:

ImportError: dlopen(/Library/Python/2.7/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Library/Python/2.7/site-packages/_mysql.so
  Reason: image not found

I was able to resolve this by setting DYLD_LIBRARY_PATH:

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
