docker容器内部的Conda构建失败

我试图将我的anaconda包构建系统与Codeship CI/CD服务集成，因此我需要在Docker容器中进行构建过程。 当前我的Dockerfile看起来是这样的：

FROM continuumio/miniconda3

COPY . .
RUN conda create --yes --name build-env python=3.8 \
    && conda install -n build-env conda-build -y \
    && conda run -n build-env conda-build --channel haasad .

RUN conda create --yes --name testing-env python=3.8 \
    && conda install -n testing-env --use-local sten -c haasad \
    && conda install -n testing-env -c anaconda pytest

生成运行时，会发生以下错误：

如何解决这个问题以及我做错了什么？

当您指定

python=3.7

时，它是否有效？我对python=3.7有类似的问题
