一年不运行代码时出现的主要错误
一年不运行代码时出现的主要错误
提问于 2022-11-19 12:02:25
嗨，我最近开始做一个项目，这个项目已经被搁置了很长时间，+- 1年。我打开了它，一些小部件(如平板按钮)被废弃了，我不得不将它们更正为that按钮等等。但是，在我尝试运行代码之后，我在调试项中发现了更多的错误，其中一些是与空安全有关的，所以我关闭了它，但即使这样，我仍然会收到一些我找不到修复的错误，而且它们太多了，需要花几天的时间来检查所有这些错误并单独修复它们，有人知道我能做些什么来修复这个错误吗？这个项目在被搁置的时候运行得很好，没有做任何改变，但是现在它已经不起作用了。以下是调试控制台提供的内容。如有任何解决办法，将不胜感激。
