在Codenvy上安装PyGame

Question

Python/Linux初学者在这里！我使用Codenvy (https://codenvy.com/)作为PyGame项目的集成开发环境。我用一行代码修改了我的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，并且发现这意味着Codenvy没有我的依赖项(PyGame)。在那篇文章中有两个文档链接：how to build a custom runtime in Codenvy和如何构建自定义机器。

到目前为止，我已经将Codenvy默认的Django +Python2.7docker文件复制到了一个新的docker文件中。我已经修改了程序用来从requirements.txt安装的代码行。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。

[DOCKER] The following NEW packages will be installed:
...
[DOCKER]ore-soundfont-gm python-numpy python-pygame tcpd x11-common

有没有人能解释一下为什么我会收到一个中止声明？如果我用来安装pygame的命令是不正确的，那么它有什么不正确的地方，我该如何修复它呢？

从那以后，我尝试使用-y标志来自动确认选择(我相信这就是我得到中止的原因，根据打印到控制台的内容)。这是我现在添加的内容。

RUN sudo apt-get install python-pygame -y --fix-missing

我得到了以下错误：

这些404与debian有关，而不是特别与pygame有关。我能做些什么来解决这个问题呢？

Answer 1

尝试更新包管理器：

运行sudo apt-get update && sudo apt-get install python-pygame -y
