我真的很挣扎polyglot，pyicu而且icu4c- 似乎我不是唯一一个......
我正在10.13.6使用 virtualenv 运行 Mac OS High Sierra 和 python3
以下是我采取的步骤，主要基于这篇文章：
- 从一个新的 virtualenv 开始
- 使用自制软件删除并重新安装 icu4c (v.62.1)
- 检查 ICU_VERSION 是否为“62.1”
- 做
ln -s /usr/local/Cellar/icu4c/62.1/bin/icu-config /usr/local/bin/icu-config - 下载 pyicu tar 文件 (2.1)
- 如链接文章中所示，提取 pyicu 并编辑 setup.py
- 构建和安装 pyicu
我懂了：
Adding CXXFLAGS="-std=c++11 -I/usr/local/Cellar/icu4c/62.1/include" from /usr/local/bin/icu-config
Adding LDFLAGS="-L/usr/local/Cellar/icu4c/62.1/lib -licui18n -licuuc -licudata" from /usr/local/bin/icu-config
Installed/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/PyICU-2.1-py3.6-macosx-10.6-intel.egg
...
Processing dependencies for PyICU==2.1
Finished processing dependencies for PyICU==2.1
正如预期的那样。
- pip3 安装多语言
当我运行我的脚本时，我得到以下信息：
File "/Users/Chris/MindWeb/Server/lib/python3.6/site-packages/polyglot/detect/__init__.py", line 1, in <module>
from .base import Detector, Language
File "/Users/Chris/MindWeb/Server/lib/python3.6/site-packages/polyglot/detect/base.py", line 11, in <module>
from icu import Locale
ModuleNotFoundError: No module named 'icu'
不足为奇，因为 PATH 中实际上没有 icu 模块。
如果，而不是步骤 5-7，我执行 pip3 install pyicu （创建 icu 文件夹），我得到：
ImportError: dlopen(/Users/Chris/MindWeb/Server/lib/python3.6/site-packages/_icu.cpython-36m-darwin.so, 2): Symbol not found: __ZNK6icu_6214Transliterator12getTargetSetERNS_10UnicodeSetE

输出otool -L /Users/Chris/MindWeb/Server/lib/python3.6/site-packages/_icu.cpython-36m-darwin.so是：
