This looks an nmslib error not a scispacy error, can you do:
pip install nmslib and see what happens ?

I just did again, and that is the error I get ...

nmslib.cc(454): error C2017: illegal escape sequence
  nmslib.cc(454): error C2001: newline in constant
  nmslib.cc(459): error C2059: syntax error: 'pybind11::enum_<similarity::DistType>'

ERROR: Failed building wheel for nmslib
  Running setup.py clean for nmslib

Then automatically runs setup.py clean for nmslib and it also fails giving:

Installing collected packages: nmslib, conllu, scispacy
    Running setup.py install for nmslib ... /

Closing as an nmslib issue.
