由于 'icu-config' 无法安装 pyicu

Question

我正在尝试根据此链接在 mac 上为 python 3.5 安装 pyicu https://struggley.wordpress.com/2015/07/14/installation-pyicu-on-mac-osx-yosemite/

但是，当我执行 pip3 install pyicu 时，我得到了这个错误

Collecting pyicu

Complete output from command python setup.py egg_info:

FileNotFoundError: [Errno 2] No such file or directory: 'icu-config'

我猜是因为我没有正确设置 icu-config 的路径。我认为以下两个可能是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

但是，我不知道如何设置它的路径。此外，我不知道为什么在教程可以顺利运行时出现此错误。

Answer 1

只需将包含icu-config的目录添加到PATH，例如：

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

如果您使用pipenv，您还可以通过.env file 更新PATH。在您的项目根目录中，创建一个名为 .env 的文件，其内容如下：

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

然后运行：

pipenv shell
pipenv install pyicu

Answer 2

我遇到了同样的问题。这对我有用

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
