The error "Failed to build pyicu==2.14" typically occurs due to missing dependencies, compiler issues, or incorrect environment configurations. Here are the steps to resolve it:
Install Required Dependencies: Ensure that pkg-config and ICU libraries are installed. On macOS, you can use Homebrew:

brew install pkg-config icu4c

Ensure Correct Compiler: Make sure you have the latest version of gcc installed:

brew install gcc

Set Environment Variables: Configure the environment variables to point to the ICU library paths:

export LDFLAGS="-L/usr/local/opt/icu4c/lib"
export CPPFLAGS="-I/usr/local/opt/icu4c/include"
export DYLD_LIBRARY_PATH="/usr/local/opt/icu4c/lib"

Force-Link ICU Libraries: Use the following command to force-link the ICU libraries:

brew link --force icu4c

Specify ICU Version During Installation: Install pyicu with a specific ICU version:

sudo ICU_VERSION=75 pip3 install pyicu

By following these steps, you should be able to resolve the build failure for pyicu==2.14. Let me know if you need further assistance!
