Answer 1

You should download VC+ compiler for windows and then try the pip install.

You can download it here https://download.microsoft.com/download/7/9/6/796EF2E4-801B-4FC4-AB28-B59FBF6D907B/VCForPython27.msi

Answer 2

As a suitable alternative would you consider running Rasa NLU in docker. The rasa/rasa_nlu:latest-full docker image includes duckling. If you wanted to get started with it and you have docker installed you should be able to just run

docker run rasa/rasa_nlu:latest-full

Then you can interact with Rasa over it's HTTP API https://github.com/RasaHQ/rasa_nlu#example-use

The docker file allow's more complicated setups like over writing the default config file and saving the logs/models/etc to a persistent disk

I had the same issue! This is basically the issue of jpype modules. You need to first install the jpype in your environment. you can use conda install -c conda-forge jpype1 For installing the jpype you can also refer to official link for jpype installation.

On successful installation of jpype duckiling can be installed using

pip install duckling -U

I hope this would help!
