Python/Linux 初学者在这里！我使用 Codenvy ( https://codenvy.com/ ) 作为 PyGame 项目的 IDE。我用一行修改了我的 requirements.txt 文件：
pygame
但是当我尝试运行它时，我从控制台收到以下消息：
[DOCKER] Collecting pygame (from -r requirements.txt (line 1))
[DOCKER] Could not find any downloads that satisfy the requirement pygame (from -r requirements.txt (line 1))
[DOCKER] Some externally hosted files were ignored as access to them may be unreliable (use --allow-external pygame to allow).
[DOCKER] No distributions at all found for pygame (from -r requirements.txt (line 1))
[DOCKER][ERROR] The command [/bin/sh -c cd /tmp/application && sudo virtualenv /env && sudo /env/bin/pip install -r requirements.txt] returned a non-zero code: 1
[ERROR] We are having trouble starting the runner and deploying application snakes_for_python. Either necessary files are missing or a fundamental configuration has changed.
Docker image build failed
我发现有另一篇文章记录了类似的问题，发现这意味着 Codenvy 没有我的依赖项（PyGame）。那篇文章中链接了两个文档：如何在 Codenvy 中构建自定义运行时以及如何构建自定义机器。
到目前为止，我已经将 Codenvy 的默认 Django + Python 2.7 docker 文件复制到一个新的 docker 文件中。我已经修改了程序用于从 requirements.txt 安装的行。这就是我现在所拥有的：
RUN cd /tmp/application && \
sudo virtualenv /env && \
sudo /env/bin/pip install -r requirements.txt && \
sudo apt-get install python-pygame
最后的 && \ 是我自己添加的。不幸的是，我在这里得到了一个错误。

有人可以解释为什么我收到中止声明吗？如果我用来安装 pygame 的命令不正确，它有什么不妥之处，我将如何修复它？
从那以后，我尝试使用该-y标志来自动确认选择（我相信这就是我中止的原因，按照打印到控制台的内容进行）。现在这是我的补充。
RUN sudo apt-get install python-pygame -y --fix-missing
我收到以下错误：

这些 404 与 debian 而不是 pygame 相关。我能做些什么来解决这个问题？
