Troubleshooting

By using the following module you might experience as unhandled promise rejection issue such as:

    at new Promise (c:\users\...\visual studio 2017\Projects\NlpTest\NlpTest\node_modules\es6-shim\es6-shim.js:1427:15)

(node:6888) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
Waiting for the debugger to disconnect...

The following issue actually occurs in es6-shim.js module, and NOT in the nlp-wordpos module itself. To resolve this issue you must comment out line 1427 in c:\users...\visual studio 2017\Projects\NlpTest\NlpTest\node_modules\es6-shim\es6-shim.js file, after installing nlp-wordpos module.

Conclusion

That's All Folks :)
