Steps to reproduce

打包前ts setup: (props) => { ... provide('aaa', 'bbb'); ... } 打包后 setup: function setup(props) { ... vue.provide('aaa', 'bbb'); ... } rollup配置中使用了external['vue'] 与output.globals={vue:'vue'} 排除vue包

What is expected?

在子组件与vue工具中可以看到名为aaa值为'bbb'的provider

What is actually happening?

浏览器控制台报错runtime-core.esm-bundler.js:38 [Vue warn]: provide() can only be used inside setup()
