vue源码新调试方式

1. 下载vue源码（https://github.com/vuejs/core）
2. 将命令改写：只是加一个-s

"build-browser-esm": "node scripts/build.js runtime reactivity shared -af esm-bundler && node scripts/build.js vue -f esm-bundler && node scripts/build.js vue -f esm-browser",

"build-browser-esm": "node scripts/build.js runtime reactivity shared -af esm-bundler && node scripts/build.js vue -f esm-bundler && node scripts/build.js vue -f esm-browser -s",

3. 源文件rollup配置文件中添加

  if (output.sourcemap) {
    output.sourcemapPathTransform = relativeSourcePath => {
      return path.resolve(packageDir, relativeSourcePath)
    }
  }

4. 将打包文件复制
5. 使用

import { createApp, ref, reactive } from '/common/sp____f/vue.esm-browser.js'
