Spyder5未找到QCoreApplication实例。未应用应用程序补丁
升级后出现以下错误 Spyder 5
No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect.
界面看起来也“不好”（我猜没有样式表）。
降级到 Spyder 4 会导致所有内容都出现在单个列中（代码区域、控制台、变量资源管理器等，所有这些都在其他列之下，并且有丑陋的重叠以使其无法使用）。
我该如何解决这个问题？
回答
（这里是 Spyder 维护者）这是一个警告，它不会影响加载我们的新样式表。请忽略它。
注意：很遗憾您不喜欢我们的风格，因为它是 Spyder 从现在开始使用的风格。
- Thanks for providing spyder. It's a great IDE!! I just installed 5.0.0 in Ubuntu, but maybe what @Hrishikesh meant with "not nice" is e.g. that all dropdown menu icons overlap with the menu texts, and tab navigator arrows are on top of the right-most tab. I don't think that is "your style" now 😉 .. I installed miniconda freshly (python 3.9.2).
- The problem with icons overlapping text will be fixed in our 5.0.1 version. The other one (navigator arrows) will be fixed in 5.0.2, to be released in three weeks.

Another question about that warning:
You say it can be ignored, but can it also be eliminated somehow? It gives me an uncomfortable feeling as if I've installed something wrong or so. Does installing a certain package (or version of it) make the warning go away?
