Which versions of sanic-cors, sanic, and sanic-plugins-framework should I use when installing allennlp==0.3.0?

Which versions of the python packages sanic-cors, sanic, and sanic-plugins-framework should I use when installing allennlp==0.3.0 with Python 3.6 or 3.7?

When I run:

conda create --name selector-py36 python=3.6 
source activate selector-py36
pip install allennlp==0.3.0

I get the error message:

sanic-plugins-framework 0.6.3.dev20180717 has requirement sanic>=0.7.0, but you'll have sanic 0.6.0 which is incompatible.
sanic-cors 0.9.6 has requirement sanic>=0.8.1, but you'll have sanic 0.6.0 which is incompatible.

which later on prevents my program relying on allennlp from running (RuntimeError: You cannot use Sanic-CORS with sanic < v0.7.0):

Solution

  • allennlp==0.3.0 doesn't have the proper dependencies:

    • it installs sanic-cors 0.9.6, which requires sanic>=0.8.1, but allennlp==0.3.0 requires sanic>=0.6.0.
    • it installs Sanic-Plugins-Framework==0.6.4.dev20181101, which will cause some ImportError: cannot import name 'logger' with sanic-cors==0.9.3.

    To fix the issue:

    pip install allennlp==0.3.0   # this will install sanic-cors==0.9.6, sanic-0.6.0 
                              # and Sanic-Plugins-Framework==0.6.4.dev20181101
pip install sanic-cors==0.9.3 # this will uninstall sanic-0.6.0 and install sanic-0.8.3 
pip install Sanic-Plugins-Framework==0.6.3.dev20180717 # this will install sanic-0.8.3
pip install sanic==0.6.0
