setup 'defineProps' is not defined

`defineProps` 是 Vue 3 中的一个函数，它用于定义组件的 props。如果您在使用 `defineProps` 时遇到错误 "setup 'defineProps' is not defined"，可能有以下几种原因：

1. 您没有正确导入 `defineProps` 函数。请确保在组件中正确导入该函数，例如：`import { defineProps } from 'vue';`

2. 您正在使用的是 Vue 2 版本，而不是 Vue 3。在 Vue 2 中，没有 `defineProps` 函数。相反，您应该使用 `props` 选项来定义组件的 props。

3. 您的开发环境中可能没有安装或正确配置 Vue 3。请确保您已经正确安装了 Vue 3，并在项目中使用了正确的版本。

defineProps is not defined

It seems like you are encountering an error message stating that "defineProps is not defined." This error typically occurs when trying to use the "defineProps" function without properly importing or declaring it in your code.

In Vue.js, the "defineProps" function is used to define props for a component. To use this function, you need to make sure that you have imported it from the appropriate package or module.

Here is an example of how to import and use "defineProps" in a Vue component:

import { defineProps } from 'vue';

export default {
  props: {
    // define your props here
  },
  setup(props) {
    // use defineProps to declare your props
    defineProps(props);

    // the rest of your component's setup logic
  },
};

Make sure that you have the correct Vue package installed and imported into your project. If you are using a bundler like webpack, double-check your configuration to ensure that the Vue package is correctly resolved.

If you are still experiencing issues, please provide more information about your code or specific error messages so that I can assist you further.
