推荐答案

您可以通过运行来卸载以前的平台

You can uninstall prior platforms by running

uninstall-hs.

您将获得类似的输出:

-- Versions found on this system
7.10.3
-- To remove a version and all earlier: uninstall-hs thru VERSION
-- To remove only a single version:     uninstall-hs only VERSION

您可以从那里继续...

And you can proceed from there...
