Question

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another post that documented a similar problem，发现这意味着Codenvy没有我的依赖（PyGame）。该帖子中链接了两个文档：how to build a custom runtime in Codenvy以及如何构建自定义计算机。

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。我已经从requirements.txt修改了程序用来安装的行。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

决赛＆amp;＆amp; \是我自己的补充。不幸的是，我在这里得到了一个错误。

[DOCKER] The following NEW packages will be installed:
...
[DOCKER]ore-soundfont-gm python-numpy python-pygame tcpd x11-common
[DOCKER] 0 upgraded, 58 newly installed, 0 to remove and 12 not upgraded.

[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.

有人可以解释我为什么要获得中止声明吗？如果我用来安装pygame的命令不正确，那么它的不当之处是什么，以及如何修复它？

编辑1：

我试图使用-y标志自动确认选择（我相信这就是我获得中止的原因，通过打印到控制台的内容）。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有关。我该怎么做才能解决这个问题？

Answer 1

尝试更新包管理器：

RUN sudo apt-get update＆amp;＆amp; sudo apt-get install python-pygame -y

在Codenvy上安装PyGame
