使用stack ghc替代ghc(Using stack ghc as replacement of ghc)

 不使用堆栈或cabal分发的包通常具有一组隐含的依赖项。 这有时意味着如果不将包安装到ghcs全局包数据库中，直接在所述包上运行ghc将无法工作。 
 
 我想使用stack ghc作为stack ghc的替代，为此我在shell shell文件中定义了以下内容： 
 
export PATH="`stack path --compiler-bin`:$PATH"
 
 现在命令ghc将使用stack的ghc - 但它不会像stack ghc那样做。 例如，它不会加载“snapshot”和“global-project”软件包数据库，可以通过以下命令看到： 
 
$ ghc -v
Glasgow Haskell Compiler, Version 8.0.1, stage 2 booted by GHC version 7.10.3
Using binary package database: ~/.stack/programs/x86_64-linux/ghc-nopie-8.0.1/lib/ghc-8.0.1/package.conf.d/package.cache
...
$ stack ghc -- -v
Glasgow Haskell Compiler, Version 8.0.1, stage 2 booted by GHC version 7.10.3
Using binary package database: ~/.stack/programs/x86_64-linux/ghc-nopie-8.0.1/lib/ghc-8.0.1/package.conf.d/package.cache
Using binary package database: ~/.stack/snapshots/x86_64-linux-nopie/lts-7.9/8.0.1/pkgdb/package.cache
Using binary package database: ~/.stack/global-project/.stack-work/install/x86_64-linux-nopie/lts-7.9/8.0.1/pkgdb/package.cache
...
 
 有没有人有关于如何使用stack ghc替代ghc 。 
 
 我目前使用的用例是我已经获得了一个引用ghc的make文件 - 但是我的机器上没有这个命令。 

Packages that are distributed without using stack or cabal usually have a set of implied dependencies. This sometimes mean that running ghc directly on said packages will not work without installing packages into ghcs global package database.
 
I would like to use stack ghc as a replacement for ghc to this end I have defined the following in my shells init file:
 
export PATH="`stack path --compiler-bin`:$PATH"
 
Now the command ghc will use stack's ghc - it does not however do the same as stack ghc. For one, it does not load the "snapshot" and "global-project" package database as can be seen with the following commands:
 
$ ghc -v
Glasgow Haskell Compiler, Version 8.0.1, stage 2 booted by GHC version 7.10.3
Using binary package database: ~/.stack/programs/x86_64-linux/ghc-nopie-8.0.1/lib/ghc-8.0.1/package.conf.d/package.cache
...
$ stack ghc -- -v
Glasgow Haskell Compiler, Version 8.0.1, stage 2 booted by GHC version 7.10.3
Using binary package database: ~/.stack/programs/x86_64-linux/ghc-nopie-8.0.1/lib/ghc-8.0.1/package.conf.d/package.cache
Using binary package database: ~/.stack/snapshots/x86_64-linux-nopie/lts-7.9/8.0.1/pkgdb/package.cache
Using binary package database: ~/.stack/global-project/.stack-work/install/x86_64-linux-nopie/lts-7.9/8.0.1/pkgdb/package.cache
...
 
Does anyone have guidance on how to achieve using stack ghc as a replacement for ghc.
 
The use-case I currently have is that I have been given a make-file that refers to ghc - but I do not have this command on my machine.
