Hi, this might seems like a recurring question regarding package installation, but i still could not run polyglot in my Mac machine after a seemingly successful installation of all the latest packages (from scratch) with the following traceback messages:

Gandhi@Quasimodo:~$ polyglot
Traceback (most recent call last):
  File "/usr/local/bin/polyglot", line 7, in <module>
    from polyglot.__main__ import main
  File "/usr/local/lib/python3.6/site-packages/polyglot/__main__.py", line 16, in <module>
    from icu import Locale

    from _icu import *
ImportError: dlopen(/usr/local/lib/python3.6/site-packages/_icu.cpython-36m-darwin.so, 2): Symbol not found: __ZNK6icu_6114Transliterator12getTargetSetERNS_10UnicodeSetE
  Referenced from: /usr/local/lib/python3.6/site-packages/_icu.cpython-36m-darwin.so
  Expected in: flat namespace
 in /usr/local/lib/python3.6/site-packages/_icu.cpython-36m-darwin.so

I checked the content of _icu.cpython-36m-darwin.so (using cat) and it seems the symbol are listed there.

I am not sure if i have missed something during the installation or if there is any corrupted lib file; can you please help me point it out? Please find them below :

  1. Installed icu4c using homebrew (brew install icu4c)

  2. Exported all required environment variables before installing the pyicu package

    $ export ICU_VERSION=61
$ export PYICU_INCLUDES=/usr/local/Cellar/icu4c/61.1/include
$ export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/61.1/lib
$ export LDFLAGS=-L/usr/local/Cellar/icu4c/61.1/lib
$ export CPPFLAGS=-I/usr/local/Cellar/icu4c/61.1/include
$ export DYLD_LIBRARY_PATH=-L/usr/local/Cellar/icu4c/61.1/lib
$ export PKG_CONFIG_PATH=/usr/local/Cellar/icu4c/61.1/lib/pkgconfig

  3. Created symlinks toward icu4c using brew link icu4c --force

  4. Installed pyicu using pip (pip3 install pyicu)

  5. Installed polyglot using pip (pip3 install polyglot)

Side note : the same tracebacks were also generated when i tried from icu import Locale in the interactive shell(does this indicate that the icu4c installation on my Mac was actually unsuccessful somehow?).

FYI, i am using "vanilla" Python 3.6.5 and MacOS High Sierra 10.13.4

Managed to solve this by reinstalling icu4c and building pyicu from scratch (and cleaned the build cache). I've wrote my workaround in details here https://stackoverflow.com/questions/50217214/import-error-for-icu-in-mac-and-ubuntu-although-pyicu-is-installed-correctly/50364835#50364835
