堆栈无法解析正确的包版本

我想用 grenade 在哈斯克尔。使用 stack 作为配置工具,我有

# stack.yaml

extra-deps:
- diagrams-solve-0.1.1
- dual-tree-0.2.2
- SVGFonts-1.6.0.3
- diagrams-core-1.4.1
- diagrams-lib-1.4.2.2
- diagrams-postscript-1.4.1
- diagrams-svg-1.4.2
- Chart-diagrams-1.8.3
- hip-1.5.3.0
- singletons-2.2
- template-haskell-2.11.1.0
- th-desugar-1.6
- grenade-0.1.0

但当我执行 stack build ,它给出了以下错误

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for th-desugar-1.6:
    template-haskell-2.12.0.0 from stack configuration does not match <2.12  (latest
                              matching version is 2.11.1.0)
needed due to Brain-0.1.0.0 -> th-desugar-1.6

Some different approaches to resolving this:

  * Set 'allow-newer: true' to ignore all version constraints and build anyway.

  * Consider trying 'stack solver', which uses the cabal-install solver to attempt to
    find some working build configuration. This can be convenient when dealing with
    many complicated constraint errors, but results may be unpredictable.

  * Recommended action: try adding the following to your extra-deps
    in [Project directory]/stack.yaml:

- template-haskell-2.11.1.0

Plan construction failed.

即使我把 - template-haskell-2.11.1.0 之前 diagrams-solve ,Stack仍然给出相同的错误。允许更新版本是不可行的,因为它会中断 th-desugar .
