问题
I have been trying to install musicbrainz server on my mac and there is a step where I have to install pip pyicu. I keep getting this error:

I have tried downloading ez_setup.py and doing python ez_setup.py. I have upgraded the setuptools and downloaded those separately as well. I am not sure what else there is to try. Please help!

I was facing this issue on my mac when trying to install polyglot (pyicu is needed for polyglot). The following resolved this for me.
# 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

I faced this issue on ubuntu 14.04 and 16.04. To fix this issue, install libicu-dev then try installing again. I did
$sudo apt install libicu-dev
$pip install pyicu

Below solution is for MAC OSX only-
try installing pyICU using brew:
brew install icu4c
if it says that it's already installed and just need to be linked, then try this:
brew link icu4c
This create relative symlinks in "/usr/local/Cellar/icu4c/..."
回答4:
Following solution worked for me on OSX:
# Install ucu4c via Brew
brew install icu4c
# Create relative symlinks for icu4c
brew link --force icu4c
# Install pyicu via pip
# Make sure ICU_VERSION matches the one you just installed
sudo ICU_VERSION=60.2 pip install pyicu
回答5:
for me to get it works:
1) install icu4c with brew:
brew install icu4c
brew link icu4c --force
2) check the version:
ls /usr/local/Cellar/icu4c/
it prompts something like:
64.2
3) execute bellow commands with substitution of proper version from previous step (first line only integer part, second and third line with decimal part):
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) finally install python package for pyicu:
pip install pyicu --upgrade
IF YOU FAIL with above (happen already to me on OS X 10.15) you may need:
brew install pkg-config
export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.3.1"'

On macOS 10.14.2 simply adding the directory containing icu-config to the PATH did the trick for me:
brew install icu4c
export PATH="/usr/local/opt/icu4c/bin:$PATH"
pip install pyicu
In fact, this is suggested by brew info icu4c:
==> Caveats
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).
If you need to have icu4c first in your PATH run:
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.zshrc
For compilers to find icu4c you may need to set:
export LDFLAGS="-L/usr/local/opt/icu4c/lib"
export CPPFLAGS="-I/usr/local/opt/icu4c/include"
For pkg-config to find icu4c you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"
回答7:
It seems like the current version of icu4c packaged for brew does not link the icu-config file properly.
Running brew link icu4c --force gives you the necessary information to address this, but fails to link it automatically.
$ brew link --force icu4c
Warning: Refusing to link macOS-provided software: icu4c
If you need to have icu4c first in your PATH run:
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.bash_profile
For compilers to find icu4c you may need to set:
export LDFLAGS="-L/usr/local/opt/icu4c/lib"
export CPPFLAGS="-I/usr/local/opt/icu4c/include"
For pkg-config to find icu4c you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"
You need to run the following after installing icu4c through brew to get icu-config into your path (assuming you're running bash as your shell):
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
After that, you should be able to install pyicu without any additional environment variables:
$ pip install --no-cache-dir pyicu

In summary, here's a complete list of commands i ran to make this work:
brew install icu4c
brew link icu4c --force
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
pip install --no-cache-dir pyicu
(As an aside, many of the solutions i came across do not use the --no-cache-dir option with pip install. I think some of them may have cached built version of pyicu. I did for a while, which masked the issue. It wasn't until i tried this option that i was able to reproduce and fix appropriately.)

I was trying to install in RHEL and I installed from the tar.gz file. Below are the commands:
/usr/local/bin/pip3 install -U setuptools
/usr/local/bin/pip3 install -U wheel
wget http://download.icu-project.org/files/icu4c/50.1.2/icu4c-50_1_2-src.tgz
tar -zxvf icu4c-50_1_2-src.tgz
cd icu
cd source
sudo ./configure --prefix=/usr
sudo make
sudo make install
icu-config --version
/usr/local/bin/pip3 install PyICU==2.0.6
