'defineProps' is not defined.

引用中的代码片段是一个示例，展示了如何在Vue 3.2中使用语法糖来定义props和setup函数。请注意，在使用defineProps之前，需要正确导入并调用该方法。

如果以上修改后仍然出现"defineProps is not defined"的错误，请确保您的项目中已正确安装Vue 3及其相关依赖，并按照文档正确使用组合式API。如果问题仍然存在，请提供更多的代码和错误信息，以便我们能够更好地帮助您解决问题。

怎么解决defineProps' is not defined.eslintno-undef

这个错误是因为在代码中使用了未定义的变量或函数。解决方法是在代码中定义这个变量或函数，或者在代码中引入定义它的文件。如果这个变量或函数是在其他文件中定义的，可以使用import语句将其引入。

如果这个变量或函数确实不存在，那么可能是代码逻辑有问题，需要检查代码并修复。

另外，也可以在ESLint配置文件中关闭这个检查，但这并不推荐，因为会影响代码质量和可读性。

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.
