在装有python2的macOS上安装pyicu 64

Question

我首先从Homebrew公式安装icu4c：

$ brew install icu4c
$ ls /usr/local/Cellar/icu4c/
64.2

然后相应地设置标志：

export ICU_VERSION=64
export PYICU_INCLUDES=/usr/local/Cellar/icu4c/64.2/include
export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/64.2/lib

然后从pip安装PyIcu

$ pip install pyicu
Successfully installed pyicu-2.3.1

但是当导入：python -c "import icu"时，我得到了错误

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/icu/__init__.py", line 37, in <module>
    from _icu import *

我在MacOS上也遇到了同样的问题，我用一个旧版本的pyicu=1.9.7解决了这个问题

$ pip install pyicu=1.9.7
