Django, Docker, collectstatic, UnicodeEncodeError: 'utf-8' codec can't encode characters in position 0-1: surrogates not allowed

Question

我希望你能在这里帮助我。在 Django 3.0.6 中运行“collectstatic”时出现 UnicodeEncodeError。我之前通过将语言环境变量 LANG 和 LC_ALL 设置为 UTF-8 修复了一个类似的错误，但在这种情况下这似乎不起作用。

我的 Django 项目在容器中运行（Docker 版本 18.03.1-ce），我刚刚升级到 Django 3.0.6。此外，在此过程中，从 Python 2.7 移至 Python 3.6。容器是“FROM python:3.6”构建的。除了collectstatic，一切正常。静态文件存储在 S3 存储桶中，并且在升级之前一切正常（由于 Python 升级，我不得不修复一些 Django 问题，但所有这些都是可预测和记录的）。

容器中的区域设置（带有错误消息）是：

    root# locale
    locale: Cannot set LC_CTYPE to default locale: No such file or directory
    locale: Cannot set LC_MESSAGES to default locale: No such file or directory
    locale: Cannot set LC_ALL to default locale: No such file or directory
    LANG=en_US.UTF-8
    LANGUAGE=en_US:en
    LC_CTYPE="en_US.UTF-8"
    LC_NUMERIC="en_US.UTF-8"
    LC_TIME="en_US.UTF-8"
    LC_COLLATE="en_US.UTF-8"
    LC_MONETARY="en_US.UTF-8"
    LC_MESSAGES="en_US.UTF-8"
    LC_PAPER="en_US.UTF-8"
    LC_NAME="en_US.UTF-8"
    LC_ADDRESS="en_US.UTF-8"
    LC_TELEPHONE="en_US.UTF-8"
    LC_MEASUREMENT="en_US.UTF-8"
    LC_IDENTIFICATION="en_US.UTF-8"
    LC_ALL=en_US.UTF-8

以及运行 collectstatic 时的消息（来自容器内）：

    root# python manage.py collectstatic

    You have requested to collect static files at the destination
    location as specified in your settings.

    This will overwrite existing files!
    Are you sure you want to do this?

    Type 'yes' to continue, or 'no' to cancel: yes

Dockerfile sn-p:

而且我很确定我可能错过了一些非常明显的东西！谢谢...

我从 Dockerfile 中注释掉以下内容并重新构建了容器，出于某种原因，这解决了问题：

    #ENV LANG en_US.UTF-8
    #ENV LANGUAGE en_US:en
    #ENV LC_ALL en_US.UTF-8
