• [ ] I have searched the issues of this repository and believe that this is not a duplicate.

Version

2.0.0-rc.2

Environment

vue3.0, antd-vue 2.0.0-rc.2 and TypeScript

Reproduction link

http://localhost:8080/

Steps to reproduce

1.create a project with vue-cli 4.5 2.install antd-vue@next 3.edit the main.ts, import antd-vue and it`s stylesheet in main.ts. 4.createApp(App).use(store).use(router).use(Antd).mount('#app') 5.use or in HelloWorld.vue

What is expected?

I expected it will show a button in my page with using global antd-vue componets.

What is actually happening?

The console throw an error and some warning when I using the or other components. The error message: Uncaught TypeError: Cannot read property 'getPrefixCls' of undefined at Proxy.render (Input.js?e36d:203) at renderComponentRoot (runtime-core.esm-bundler.js?5c40:696) at componentEffect (runtime-core.esm-bundler.js?5c40:4035) at reactiveEffect (reactivity.esm-bundler.js?a1e9:42) at effect (reactivity.esm-bundler.js?a1e9:17) at setupRenderEffect (runtime-core.esm-bundler.js?5c40:4018) at mountComponent (runtime-core.esm-bundler.js?5c40:3976) at processComponent (runtime-core.esm-bundler.js?5c40:3936) at patch (runtime-core.esm-bundler.js?5c40:3547) at mountChildren (runtime-core.esm-bundler.js?5c40:3736)

Thanks for your answer. I had solved the problem. It may caused by the cnpm tools. When I delete the node_modules folder and use npm to install the package, it worked well.
