Hello,

I am encountering the following error while using the Python Spire.Doc library within a Docker container:

I have searched online for solutions and tried several methods, but none have worked so far. Do you have any suggestions on how to resolve this issue?

Thank you for your help.

Hello,

Thanks for your inquiry.
Kindly note that the conversion file will read the font files in the "/usr/share/fonts“ directory, so before converting, please make sure that the fonts used in the word file have been installed in the container. In addition, the docker container does not seem to have a font directory by default. So you need to create this directory first and then install the fonts for the container. You can also search on Google for how to install fonts for Docker containers. If you have any other questions, please feel free to write back.

Sincerely,
William

We had a very similar issue in a Debian-based container! The solution for us was to add the following lines to the Dockerfile:

Code: Select all: RUN echo "deb http://deb.debian.org/debian bookworm contrib non-free" > /etc/apt/sources.list.d/contrib.list RUN apt-get update && apt-get install -y --no-install-recommends ttf-mscorefonts-installer ENV LD_LIBRARY_PATH=/usr/share/fonts:usr/local/share/fonts
