问题

Mac 下通过 pip 安装 icu 失败。

解决办法及原因

问题的原因是因为icu库中的某一行代码找不到一个文件，获取不到ICU_VERSION的值。

# Install icu

brew install icu4c

# check newest version

ls /usr/local/Cellar/icu4c/

# Edit pyicu installer to work

git clone https://github.com/ovalhub/pyicu.git

# edit setup.py not to query for the version, i.e. change

# ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()

# to whatever your version is, e.g.

# ICU_VERSION = '57'

# Install pyicu

env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib python setup.py build

env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib sudo python setup.py install

# Change DYLD_LIBRARY_PATH (not sure if req'd)

DYLD_LIBRARY_PATH=/usr/local/Cellar/icu4c/57.1/:$DYLD_LIBRARY_PATH

echo $DYLD_LIBRARY_PATH

# Icu works now from python, and you can proceed with polyglot

$ python

>>> import icu

$ pip install polyglot

$ python

>>> import polyglot
