使用dockercompose生成时出现错误：\uuuu init\uuuu（）获得意外的关键字参数“interpolate”

Question

我是docker新手，在运行docker-compose build命令时，我遇到了这个错误

Answer 1

容器中的代码使用的python-dotenv版本比requirements.txt文件中列出的版本更新，因为interpolate option是在v0.11.0中添加的

您需要将requirements.txt中的版本更改为0.11.0（或最新版本），然后重新安装依赖项

您的容器似乎使用了virtual environment。您可能需要通过在Dockerfile中运行pip install，或者通过预先在本地运行来检查容器中的依赖项是否正确更新
