我一直在为此苦苦挣扎，我需要一些帮助。我正在尝试创建python应用程序的docker映像。我的应用程序使用orjson（Python的快速JSON库）。该库的某些部分是使用rust构建的，因此我需要rust工具链。现在最重要的是，我使用Alpine的原因是它的占地面积小，因此它不附带任何标准工具。我需要自己动手做。
这是我的Dockerfile来模拟问题。
FROM python:3.7-alpine
# for orjson in requirements.txt
RUN apk add rust cargo
RUN pip install orjson
这是我面临的错误消息。

我对于在Alpine中获得防锈环境应安装的设备有些困惑。任何帮助，将不胜感激。

感谢@ nitishkumar-singh的回复，我设法使它能够正常工作。该帖子中存在一些错误，如果有人遇到此问题，这是我的Dockerfile。
