在用于 Flask 应用程序的 docker 容器中安装 pythonnet

问题描述

我正在尝试在 docker 映像上安装 pythonnet - 尽管我一直遇到以下问题。有没有人能够建议正确的方法：

''' 克隆到“pythonnet”... 回溯（最近一次调用最后一次）：文件“pythonnet/setup.py”，第 196 行，在 with open("README.rst","r") as f: FileNotFoundError: [Errno 2] 没有这样的文件或目录：'README.rst' '''

Dockerfile：

FROM python:3.7-slim
