Run following commands

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

It will solve this.

Make sure to match the .UTF-8 part to the actual syntax found in the output of locale -a e.g. .utf8 on some systems.

The problem is most likely caused by the fact that LC_CTYPE is somehow, somewhere set to "UTF-8", which is not a valid locale name. So you need to figure out how it happens and delete that incorrect setting.

Hey @bryce, good catch, I hadn’t! To get this working on Community Cloud, create a packages.txt file in your repo containing: locales locales-all Then the following code should work: import locale import streamlit as st def format_money(res: int) -> str: """ Given some int, convert it t…

The root cause is: your environment variable LC_ALL is missing or invalid somehow

Short answer-

just run the following command:

$ export LC_ALL=C

Hello, Instead of using apprunner.yaml, you can: **Customize a Docker Container:** * Build a Docker container locally with your required locale settings. * Push the container to Amazon ECR. * Use this custom container in AWS App Runner. **Install Locale Packages in apprunner.yaml:** * If you prefer using apprunner.yaml, add the necessary locale package installation: ``` version: 1.0 runtime: python311 build: commands: pre-build: - yum install -y glibc-all-langpacks - export LC_ALL=es_ES.UTF-8 - export LC_TIME=es_ES.UTF-8 - export LANG=es_ES.UTF-8 build: - pip3 install pipenv - pipenv install run: runtime-version: 3.11.9 pre-run: - pip3 install pipenv - pipenv install command: pipenv run gunicorn conf.wsgi --workers 2 --log-file - network: port: 8000 ``` https://docs.aws.amazon.com/apprunner/latest/dg/service-source-code.html#service-source-code.managed-platforms https://docs.aws.amazon.com/linux/al2023/ug/image-comparison.html
