推荐答案

IRC的用户dysfun回答了我的问题，因此我将其张贴在这里以供后代参考.

User dysfun from the IRC answered my question so I will post it here for posterity.

要更新用于编译项目的GHC，请转到项目的stack.yaml文件.

To update GHC that's used to compile a project, go to the project's stack.yaml file.

其中存在解析器字段.相应地更新.一些例子:

In there is the resolver field. Update that accordingly. Some examples:

resolver: ghc-8.0.2
resolver: lts-9.0
resolver: nightly-2015-09-21

对于我来说，我从此网页了解到，解析器lts-9.0使用GHC 8.0 .2.

For my case, I learned from this webpage that resolver lts-9.0 uses GHC 8.0.2.
