Python异常处理TypeError: translation() got an unexpected keyword argument ‘codeset‘

背景

学习graphql-python安装好依赖后执行命令

python 复制代码

python manage.py migrate
python manage.py runserver

仅接着出现下列错误，主要提示是「TypeError: translation() got an unexpected keyword argument 'codeset'」

python 复制代码

        return gettext_module.translation(
            domain=self.domain,
            localedir=localedir,
            languages=[self.__locale],
            codeset='utf-8',
            fallback=use_null_fallback,
        )

分析与解决

根据异常栈定位到源代码位置 /Users/software_1/miniconda3/envs/learnLangchain/lib/python3.11/site-packages/django/utils/translation/trans_real.py，代码调用python方法传入参数codeset

python 复制代码

        return gettext_module.translation(
            domain=self.domain,
            localedir=localedir,
            languages=[self.__locale],
            codeset='utf-8',
            fallback=use_null_fallback,
        )

当前python版本为3.11，源码查看并没有该参数。随后看了教程文章，前置依赖要求是python3.6。接着看了一下Django版本为2.1.4，所以是版本间冲突导致。

解决：最终有两种解决方式，升级Django版本或者切换python版本

查看Django最新版依赖要求，升级到最新版解决问题。
使用python3.6
