构建 Docker 映像时出错。 “例外：找不到 Cython 生成的文件‘pandas/_libs/algos.c’。”

Question

我以前可以基于以下构建docker镜像

Dockerfile

FROM python:3.7 

COPY ./* ./app/
WORKDIR /app/

RUN pip install -r requirements.txt

EXPOSE 80
CMD ["python", "application.py"]

requirements.txt

Flask==1.1.1
Werkzeug==1.0.1
Flask-Cors==3.0.8
pandas==0.25.0

但由于某种原因，现在出现以下错误：

Exception: Cython-generated file 'pandas/_libs/algos.c' not found.

Cython is required to compile pandas from a development branch.

Please Cython or download a release package of pandas.

也观察到了

Building wheel for pandas (setup.py): started 在此过程的早期。

我能够在 anaconda python 3.7 环境中运行 application.py，使用完全相同的库版本，但不确定为什么无法构建 Docker 映像。

任何指针将不胜感激！
