Published package.json has workspace declared

When working on my project, I'm getting warnings from yarn about private packages and workspaces. I've tracked it down to this package and was wondering if you could release an update where that the deployed package.json file doesn't list `workspaces`? You can find out more about it [here](https://github.com/yarnpkg/yarn/issues/8580) on yarn's issues.

```cmd
$> warning Workspaces can only be enabled in private projects.
```

该 issue 没有指定源文件或测试。先检查 package 发布配置和生成的 package.json，然后在可能的情况下复现 Yarn 警告。当已发布的 package.json 不再声明 workspaces，同时 package 仍可发布时，即视为完成。
