尝试使用Dockerfile下载requirements.txt时哈希值错误

Dockerfile：

RUN pip install --no-cache-dir -r /requirements.txt

在每个构建命令之后仍然出现的错误：

The command '/bin/sh -c pip install --no-cache-dir -r /requirements.txt' returned a non-zero code: 1

我在这方面缺少什么吗？

引用此内容：使用pip安装时，Python包哈希值不匹配

但是到目前为止还没有成功。

另外，我可以减少上一条语句的构建时间吗？Requirements.txt中大约有85个库，每个构建结果大约需要10分钟。
