由于“icu-config”，无法安装pyicu。

Question

根据这个链接https://struggley.wordpress.com/2015/07/14/installation-pyicu-on-mac-osx-yosemite/，我试图在mac上安装pyicu for python3.5

然而，当我执行pip3安装pyicu时，我得到了这个错误。

Collecting pyicu
Using cached PyICU-1.9.5.tar.gz
Complete output from command python setup.py egg_info:

    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'icu-config'

我想这是因为我没有正确设置icu配置的路径。我认为下面两个可能是icu-config文件。

/usr/local/Cellar/icu4c/58.1/bin/icu-config
/usr/local/Cellar/icu4c/58.1/share/man/man1/icu-config.1

然而，我不知道如何设置这条道路。此外，我不知道为什么我得到这个错误，而教程可以顺利工作。

Answer 1

我也有同样的问题。这对我来说很管用

brew install intltool icu4c gettext
brew link icu4c gettext --force
CFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib pip3 install pyicu

Answer 2

只需将包含icu-config的目录添加到PATH中，例如：

brew install icu4c
export PATH="/usr/local/opt/icu4c/bin:$PATH"
pip install pyicu

如果使用pipenv，还可以通过 file更新PATH。在项目根目录中，创建一个名为.env的文件，其内容如下：

PATH="/usr/local/opt/icu4c/bin:${PATH}"

然后跑：

pipenv shell
pipenv install pyicu
