[Python] Install polyglot on Mac

reference: https://medium.com/hackernoon/install-polyglot-on-mac-3c90445abc1f

 

There is no mac-compatible version of polyglot python package in conda channels. Therefore, we have to install it via secondary method. It is a bit problematic as it raised error when installing via "pip" (even though no error, when it is imported, it raised a dependency errors). 

 

• First let us install the icu4c library using brew.

$ brew install icu4c

• Check installation using

$ ls -l /usr/local/opt/icu4c/include/

• Now install pyicu

$ CFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.0.3"' pip install pyicu

 

Then install polyglot

pip install polyglot
