python - 路径库:无法从 'Sequence' 导入名称 'collections'

Question

我重建我的项目已经有几天了，但是当我今天早上测试一些东西时，我想更新我的 Werkzeug 包，因为我的 Multidict 类有问题，我重建并开始收到这个错误:

#17 73.14     ERROR: Command errored out with exit status 1:

我试图在我的本地机器上安装依赖项 requirements.txt 并且它运行没有任何问题，但是当构建 docker 镜像时它出错了

Docker 文件:

WORKDIR /usr/src/app

COPY . .

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

EXPOSE 5010

RUN chmod u+x ./entrypoint.sh

我还尝试将 pathlib 从需求文件中取出，以便其他依赖项可以自己安装它，尝试了多个版本的 pathlib，但它仍然出错:

#9 86.72 ERROR: Could not find a version that satisfies the requirement pathlib (from artifactory) (from versions: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.97, 1.0, 1.0.1)
#9 86.72 ERROR: No matching distribution found for pathlib

如有任何帮助，我们将不胜感激。

如果您查看基本图像，您会发现它刚刚在 27 小时前更新。

$ docker images python:3
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
python              3                   618fff2bfc18        27 hours ago        915MB

事实上，从它的docker hub ，python:3 标签现在指向 python 3.10.0，而不是几天前您编写 Dockerfile 时的 python 3.9。

要解决由第三方库引起的任何不兼容问题，您最好再次将基础镜像降级为 python 3.9:

FROM python:3.9
