崩溃、Python和Google日历API

啊

我按照googlecalendarapi的文档（）和本教程（）创建了一个闹钟。原理很简单。我把一个事件放在我的日历上，如果它在“树莓”日历上，并且当时间=指定的时间时描述为“唤醒”，它会在Pi上播放我的音乐

除了当我运行我的脚本时，它会在一段可变的时间内工作，然后会因随机错误而崩溃

很难具体诊断，但如果我冒昧猜测的话——这看起来像是网络连接不良，而不是脚本的任何问题。我真的不认为这是一个网络问题，因为我使用了其他一些连接到互联网的脚本，它们不会像这样“崩溃”……或者可能是谷歌服务器的连接问题？我在3个小时前重新启动了我的脚本，现在仍然没有任何问题难以明确诊断，但如果我冒险猜测的话——看起来网络连接不好，而脚本有任何问题。我真的不认为这是网络问题，因为我使用了其他一些连接到internet的脚本，它们不会“崩溃”就像这个……或者是谷歌服务器的连接问题？我在3小时前重新启动了脚本，但仍然没有任何问题（目前）
