在vue2.6中使用这个，报错The setup binding property "addCount" is already declared，setup函数导出的每一个属性都会有一个警告，这是为什么？

We temporarily close this due to the lack of enough information. Please provide a minimal reproduction to reopen the issue. Thanks.

Why reproduction is required

I got the same problem. I created a new project by vue cli and installed composition API, then encountered the situation.

Edit: I might found the problem. The version of vue in package.json is ^2.6.14, so 2.7.7 is installed. The problem is solved if I specify the version to 2.6.14.
