I get the following error installing sasl in my Bluemix app: ``` Installing collected packages: sasl, thrift-sasl Running setup.py install for sasl: started Running setup.py install for sasl: finished with status 'error' Command "/app/.heroku/python/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-9mi8225r/sasl/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('

Accepted Answer

The solution for me was to use pure-sasl and install imypla and thrift_sasl from application code rather than my requirements.txt:

```
try:
    import impyla 
except ImportError:
    print("Installing missing impyla")
    import pip
    pip.main(['install', '--no-deps', 'impyla'])

try:
    import thrift_sasl
except ImportError:
    print("Installing missing thrift_sasl")
    import pip
    # need a patched version of thrift_sasl.  see https://github.com/cloudera/impyla/issues/238
    pip.main(['install', '--no-deps',  'git+https://github.com/snowch/thrift_sasl'])
```

I added this code to a view in my flask application: https://github.com/snowch/movie-recommender-demo/blob/master/web_app/app/main/views.py
