I am trying to install several packages on a virtual environment on a Mac (OS X El Capitan 10.11.6). I have successfully installed polyglot (version 16.7.4). Everything works fine until I launched Python (version 3.6).

This is what I get as a result of a try to import text from polyglot.

>>> import polyglot
>>> from polyglot import text
sh: grep: command not found
sh: sysctl: command not found
sh: sw_vers: command not found
sh: grep: command not found
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<WORKING DIRECTORY>/lib/python3.6/site-packages/polyglot/text.py", line 9, in <module>
from polyglot.detect import Detector, Language
  File "<WORKING DIRECTORY>/lib/python3.6/site-packages/polyglot/detect/__init__.py", line 1, in <module>
from .base import Detector, Language
  File "<WORKING DIRECTORY>/lib/python3.6/site-packages/polyglot/detect/base.py", line 11, in <module>
from icu import Locale
ModuleNotFoundError: No module named 'icu'
>>>

To create the virtual environment I ran the venv module as a script with the directory path.

Any idea on what to do?

The author of polyglot has forgotten to list requirements in setup.py so pip install polyglot doesn't install them automatically. Please report the bug to the issue tracker.

Meanwhile dowload polyglot sources and run

pip install -r requirements.txt

  • Thanks the problem seems that it doesn't install PyICU, which is required. This error comes up (even after downloading the source): ./common.h:105:10: fatal error: 'unicode/utypes.h' file not found – paoloeusebi Sep 28 '17 at 21:31

    To compile PyICU you need to [compile ICU](https://github.com/ovalhub/pyicu#building-pyicu) first. – phd Sep 28 '17 at 21:53
