No valid versions available for imooc-datav-libs-dev

Question

1.每次停掉服务，安装任意npm包，就需要重新npm link imooc-datav-libs-dev。
2.npm install xxx命令是正常的，但npm uninstall 任意的包，就会报这个错误。
请老师或者知道为什么的同学，帮忙看下会是什么原因引起的？

npm 6.14.6
node 12.18.3
nvm 1.1.7

同学你好，imooc-datav-libs-dev 这个包是课程中通过rollup封装的，还没有发布到线上，在使用时需要通过npm link导入，出现报错的时候在node_modules中找一下看看这个包是否存在。可是实在删除链接的时候被删除掉了。

  额，老师，那为什么会在npm link 自定义本地包之后，想卸载任何包都会报图上的错误信息（错误都指向自定义本地包）。会不会是我在npm link的时候，操作方法不对导致的？

  可以把你npm link的操作步骤说一下吗
