Install Pyicu in python 3.x

Question

My system is Windows 10 x64

Now I would like to install pyicu but I encounter with a problem like this

Collecting pyicu

Using cached PyICU-1.9.7.tar.gz Complete output from command python setup.py egg_info: Traceback (most recent call last): File "C:\\Users\\ANHVU\\AppData\\Local\\Temp\\pip-build-v5fb9ri4\\pyicu\\setup.py", line 12, in ICU_VERSION = os.environ['ICU_VERSION'] File "C:\\Users\\ANHVU\\AppData\\Local\\Programs\\Python\\Python35\\lib\\os.py", line 725, in getitem raise KeyError(key) from None KeyError: 'ICU_VERSION'

RuntimeError:

How can I resolve this? Help me pls.

Answer 1

You can download a corresponding whl file from Unofficial Windows Binaries for Python Extension Packages

For example, the latest version (as of Jan 13 2019) for your 64-bit Windows and Python3.7 version is PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

Then open the Windows Powershell console as Administrator, cd to the directory where you put the whl file and execute the following command:

python -m pip install .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

or (if you already have a previous PyICU version installed)

python -m pip install -U .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

Answer 2

For the record:

My system (Win 10, 64 bit, python 3.8) gave me the exact same error message.

The solution was to install the 32-bit version of the PyICU whl file, not the 64 bit version.
