如何構建允許我使用reflex-frp作爲依賴項目生成項目的堆棧配置？

Question

如有問題。我無法獲得工作堆棧配置。我想要構建使用ghc反射的項目，最好是8.0.2或更高。 我該怎麼做，因爲指定它作爲一個額外的代價似乎不工作要麼..

Answer 1

看起來像沒有發佈的版本的reflex支持ghc 8.0.2。有很多自0.4版本上develop分支的變化：https://github.com/reflex-frp/reflex/compare/cc62c11a6cde31412582758c236919d4bb766ada...develop

所以首先我嘗試這樣做：

resolver: lts-9.5 

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

但是，這導致：

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 

遵循建議的行動產量一個工作的配置：

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
