Running error:

[Vue warn]: Failed to resolve component: el-button
If this is a native custom element, make sure to exclude it from component resolution via compilerOptions.isCustomElement.
at <App>
problem analysis:
If you use vue2, it runs normally. It should be that vue3 is not compatible with element UI.
Element UI is an interface framework based on Vue2.x; Element Plus is an interface framework based on Vue3.x;
solve
For vue3, use element Plus instead.
Source code:
Note: Before mounting vue, elementplus must be loaded
app.use(ElementPlus)
