Error - Couldn't find a valid ICU package installed on the system

Aspose.Words Product Family
#1

I’m a beginner, just trying to get started on using the aspose.words library for python, but I’ve hit an immediate roadblock. I used pip install aspose-words which appears to work. However, when trying to run the test script exactly as seen in the product page, I get the following error:

Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

Aborted (core dumped)

The error appears to happen as soon as aw.Document() is called for the first time.

My os is linux (Kubuntu 22.10).

Any idea where I can start fixing this issue?

@OliverG Please see our documentation to learn about additional requirements of Aspose.Words in Linux:
https://docs.aspose.com/words/python-net/system-requirements/#system-requirements-for-target-linux-platform

Also, it might be required to install libicu-dev package. Here is working Dockerfile configuration on Ubountu:

FROM ubuntu:20.04

ENV DEBIAN_FRONTEND="noninteractive"

RUN apt-get update -y
RUN apt-get install -y python3-pip
RUN apt-get install -y libpython3.7
RUN apt-get install -y pkg-config libicu-dev

WORKDIR /usr/app/src

# Copy function code
COPY app.py ./

RUN  pip install aspose-words

CMD [ "python3", "app.py"]
