Error installing pip pyicu

Question

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!

Answer 1

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

Answer 2

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

Answer 3

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"'

Answer 4

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"

Answer 5

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/..."

Answer 6

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

Answer 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

  Running setup.py install for pyicu ... done

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.)

Answer 8

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

Answer 9

This fails because icu4c is a keg-only formula as you can see in the Caveats section of brew info icu4c .

Some other answer recommend to use brew link icu4c but that may cause other issues as macOS already provides libicucore.dylib .

pip install pyicu fails because

• will try run icu-config command, so icu-config must be in the PATH
• will try to run pkgconfig ... icu-i18n so the .pc files for icu4c must be in the PKG_CONFIG_PATH

For macOS if you don't want to brew link icu4c and just want to make icu4c available to your pip install command then you can do this instead:

brew install pkg-config icu4c

# brew info icu4c 
export PATH="/usr/local/opt/icu4c/bin:$PATH"
export PATH="/usr/local/opt/icu4c/sbin:$PATH"
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

icu-config --version # 68.2
pkg-config --modversion icu-i18n # 68.2

pip install pyicu==2.6.0 # works because icu-config in PATH and pkgconfig can find icu4c
