使用 python2 在 macOS 上安裝 pyicu 64

Question

我首先從 Homebrew 公式安裝了icu4c ：

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

然后相應地設置標志：

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

然后從pip安裝 PyIcu：

$ pip install pyicu
Successfully installed pyicu-2.3.1

但是在導入時： python -c "import icu"我得到了錯誤

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 上遇到了同樣的問題，我通過使用舊版本的 pyicu=1.9.7 解決了它

$ pip install pyicu=1.9.7
