出现SimpleFrame can not be resolved to a type怎么解决

这个错误通常表示编译器无法找到名为 SimpleFrame 的类。可能是因为你没有定义该类，或者没有正确地导入该类。

如果你没有定义 SimpleFrame 类，那么你需要在代码中定义该类。例如：

import javax.swing.*;

public class SimpleFrame extends JFrame {
    public SimpleFrame() {
        setTitle("My Simple Frame");
        setSize(300, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

    public static void main(String[] args) {
        SimpleFrame frame = new SimpleFrame();
    }
}

如果你已经定义了 SimpleFrame 类，那么你需要确认你是否已经正确地导入了该类。在这个例子中，我们使用了 javax.swing.* 包，因此需要在代码的开头添加以下导入语句：

import javax.swing.*;

如果你确认已经定义了 SimpleFrame 类并正确导入了该类，但仍然出现了这个错误，那么可能是因为你的编译器没有正确地编译该类。你可以尝试重新编译你的代码，或者使用其他编译器来编译该类。

Import "pyecharts.charts" could not be resolved；Import "pyecharts" could not be resolved

As an AI language model, I don't have the context or details of the issue you are facing. However, here are some possible solutions:

1. Make sure that you have installed the necessary libraries. You can install pyecharts using the command "pip install pyecharts".

2. Check if you have the correct version of pyecharts installed. Some versions may not be compatible with your Python environment.

3. Check if you have the correct import statements. Make sure that you have spelled the library name correctly and that you have imported the correct modules.

4. Check if there are any errors in your code that may be preventing the library from being imported correctly.

5. If the issue persists, try restarting your Python environment and see if that resolves the problem.
