如何构建允许我使用reflex-frp作为依赖项目生成项目的堆栈配置？

Question

如有问题。我无法获得工作堆栈配置。我想要构建使用ghc反射的项目，最好是8.0.2或更高。 我该怎么做，因为指定它作为一个额外的代价似乎不工作要么..

Answer 1

看起来像没有发布的版本的reflex支持ghc 8.0.2。有很多自0.4版本上develop分支的变化：https://github.com/reflex-frp/reflex/compare/cc62c11a6cde31412582758c236919d4bb766ada...develop

所以首先我尝试这样做：

resolver: lts-9.5 

packages: 
- . 
- location: 
    git: https://github.com/reflex-frp/reflex 
    commit: 916c876 
    extra-dep: true 

但是，这导致：

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

    In the dependencies for reflex-0.5.0: 
     prim-uniq must match >=0.1.0.1 && <0.2, but the stack configuration has no specified version 
       (latest applicable is 0.1.0.1) 
     ref-tf must match ==0.4.*, but the stack configuration has no specified version (latest applicable is 0.4.0.1) 
    needed due to hmm-0.1.0.0 -> reflex-0.5.0 

    Recommended action: try adding the following to your extra-deps in /home/mgsloan/fpco/test-stack/stackoverflow46391975/hmm/stack.yaml: 
    - prim-uniq-0.1.0.1 
    - ref-tf-0.4.0.1 

遵循建议的行动产量一个工作的配置：

resolver: lts-9.5 

packages: 
- . 
- location: 
    git: https://github.com/reflex-frp/reflex 
    commit: 916c876 
    extra-dep: true 

extra-deps: 
- prim-uniq-0.1.0.1 
- ref-tf-0.4.0.1
