安装pip pyicu时出错

Question

我一直试图在我的mac上安装musicbrainz服务器，有一步我必须安装pyicu。我一直在犯这个错误：

Collecting pyicu

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-E50o2C/pyicu/

我试过下载ez_setup.py并做python ez_setup.py。我已经升级了setuptools，并分别下载了这些工具。我不知道还有什么可以尝试的。请帮帮我！

当我试图安装polyglot时，我在我的mac上遇到了这个问题(polyglot需要pyicu)。下面为我解决了这个问题。

# Install icu
brew install icu4c

# check newest version
ls /usr/local/Cellar/icu4c/

# Edit pyicu installer to work
git clone https://github.com/ovalhub/pyicu.git

# edit setup.py not to query for the version, i.e. change
# ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()
# to whatever your version is, e.g.
# ICU_VERSION = '57.1'

# Install pyicu
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib python setup.py build
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib sudo python setup.py install

# Change DYLD_LIBRARY_PATH (not sure if req'd)
DYLD_LIBRARY_PATH=/usr/local/Cellar/icu4c/{version, e.g. 57.1}/:$DYLD_LIBRARY_PATH
echo $DYLD_LIBRARY_PATH

# Icu works now from python, and you can proceed with polyglot
$ python
>>> import icu
$ pip install polyglot
$ python
>>> import polyglot

我在ubuntu 14.04和16.04上遇到了这个问题。若要解决此问题，请安装libicu-dev，然后再尝试安装。我做到了

$sudo apt install libicu-dev
$pip install pyicu

对我来说是可行的：

1)用brew安装icu4c：

brew install icu4c
brew link icu4c --force

2)检查版本：

ls /usr/local/Cellar/icu4c/

它提示如下：64.2

3)执行以下命令，并从前一步替换正确的版本(第一行只有整数部分，第二行和第三行用十进制部分)：

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

4)最后为pyicu安装python包：

pip install pyicu --upgrade

如果上面的操作失败(在OS X10.15上已经发生在我身上)，您可能需要：

brew install pkg-config

export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.3.1"'
