无法在MacOS上安装pyicu

Question

我尝试通过pip3 install pyicu进行安装，得到了以下错误：

Collecting pyicu
Using cached https://files.pythonhosted.org/packages/bb/ef/3a7fcbba81bfd213e479131ae21445a2ddd14b46d70ef0109640b580bc5d/PyICU-2.0.3.tar.gz

Complete output from command python setup.py egg_info:

Building PyICU 2.0.3 for ICU 61

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/80/v1nwf70x2rz5srmzfnpc3pq40000gn/T/pip-build-b_sify1x/pyicu/

然后，我从一些来源了解到，我需要安装icu4c并通过.bash_profile为icu配置。也试过这样做，但错误仍然存在。请帮帮我。

尝试在命令行中运行以下命令：

export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.0.3"'
