我已经在谷歌上搜索了将近一个星期，我知道有类似的问题，但没有一个有答案。所以这里还有一个，希望能找到答案。我为我的孩子编写了一个小程序，其中出现了一个单词，发音并在清除单词后她需要重现它。我使用 pyttsx3 作为语音模块，因为它可以离线使用。程序运行良好，但为了让她更有吸引力，我决定用 tkinter 构建一个 GUI。现在发生的情况是窗口已构建，显示的单词已发音，但之后程序关闭而没有任何错误。为了检查程序执行了多远，我在每一行之后使用了一个打印命令。打印命令被执行，并且在终端中可见。与 tkinter 相关的每隔一行都不会执行。

再说一遍：pyttsx3 可以正常工作，tkinter 也可以，但在一个程序中却不能。如果您删除行 engine.runAndWait() 程序执行正常，只是没有语音。

为什么会发生这种情况，我该如何解决？非常抱歉，请向我解释一下，就像我是一个 40 岁的家庭主妇一样，正在尝试学习一项新技能，没有任何编程或 CS 背景，谢谢。

这是我的代码，如果有点乱，抱歉，几周前才开始 :-)

这是词汇表.json 文件：

{
    "words": [
        "huis",
        "muis",
        "bal",
        "vuur",
        "muur",
        "ik",
        "zon",
        "hok",
        "poep",
        "aap",
        "noot",
        "hij",
        "zij",
        "test",
        "woord"
    ]
}

这是我使用的图片的链接：https ://www.obsbeekbergen.nl/wp-content/uploads/sites/34/2016/04/dictee.gif

程序关闭时终端中的输出（同样，没有错误）：

after clear text
after update
after creating entry box
after positioning entry window
after creating button
after words.remove

我将 python 3.8.5 与 MacOs Mojave 10.14.6 一起使用。
