当我尝试执行Oppia的安装过程时，会抛出一条错误消息：

我真的无法理解错误信息。我应该安装一些软件包吗？你知道吗

Answer 1

您（或安装程序）实际运行的是Python2.7吗？你知道吗

行：with zipfile.ZipFile(TMP_UNZIP_PATH, 'r') as z:是一个with语句，它需要ZipFile实例来支持上下文管理器接口，即需要定义__enter__()和__exit__()方法。你知道吗

对ZipFile的上下文管理器支持是在版本2.7中添加的，而对python3的上下文管理器支持是在版本3.2中添加的。您使用的Python版本不正确。你知道吗
