Error installing pip pyicu

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:

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

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!

Solution

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
