Cannot install pynput using talon's pip

[mqnc]

I am running Ubuntu 18.04.

Running ~/.talon/bin$ ./pip install pynput causes

   ERROR: Command errored out with exit status 1:

Just for testing I also installed matplotlib which worked fine.

EDIT:

Sorry, matplotlib was already there. However, I could install flask but not dragonmapper.

fixed in next beta by setting LD_LIBRARY_PATH in .talon/bin/python
