为Atom (原子- Haskell )配置haskell(堆栈)时出现的问题

Question

我对haskell一无所知，我正试图在linux上设置堆栈(静态)2.1.3-3来处理Atom1.45中的包，但它不起作用。

atom-haskell的安装创建了2条错误消息：-Failed激活ide-haskell包，结果已经连接！错误是从ide-haskell包抛出的。这一问题已经有报道。(github.com/atom-haskell/ide-haskell/issues/138) -Atom找不到ghcmod可执行文件

所以我看了看https://atom.io/packages/atom-haskell，并了解到要建立二进制文件，我必须使用

堆栈安装ghc-mod hoogle hasktag

但这是行不通的：

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

https://atom-haskell.github.io/core-packages/haskell-ghc-mod/#using-with-stack上的“警告”解决了ghcmod问题:在~/..stack/global-project/stack.yaml中将解析器版本设置为lts-9.21 (上面写着"lts-9“--这更正确吗？)有更多的说明在该网站，但我不明白他们。

现在出现了一个新的错误：

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

In the dependencies for pointfree-1.1.1.6:
    haskell-src-exts-1.18.2 from stack configuration does not match ==1.20.*  (latest matching version is 1.20.3)
needed since pointfree is a build target.
Some different approaches to resolving this:

  * Set 'allow-newer: true' in /home/bradz/.stack/config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps in /home/bradz/.stack/global-project/stack.yaml:

- haskell-src-exts-1.20.3@sha256:83ae523bbec907a42c043de1f5bbf4c1554e7c3b898af07bb1ce6e80eaa282ec,4589

Plan construction failed.

因此，我按照建议将其添加到我的stack.yaml中，现在看起来如下所示：

packages: []
resolver: lts-9.21
extra-deps:
- haskell-src-exts-1.20.3@sha256:83ae523bbec907a42c043de1f5bbf4c1554e7c3b898af07bb1ce6e80eaa282ec,4589

但这似乎是错误的，因为现在我又收到了ghcmod错误，甚至更多：

$ stack install ghc-mod hoogle hasktags pointfree pointful cabal-install

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

In the dependencies for ghc-mod-5.8.0.0:
    haskell-src-exts-1.20.3 from stack configuration does not match <1.20 && >=1.18  (latest matching version is 1.19.1)
needed since ghc-mod is a build target.

In the dependencies for haskell-src-exts-simple-1.19.0.0:
    haskell-src-exts-1.20.3 from stack configuration does not match >=1.18 && <1.20  (latest matching version is 1.19.1)
needed due to pointful-1.0.9 -> haskell-src-exts-simple-1.19.0.0

In the dependencies for hlint-2.0.11:
    haskell-src-exts-1.20.3 from stack configuration does not match >=1.18 && <1.20  (latest matching version is 1.19.1)
needed due to ghc-mod-5.8.0.0 -> hlint-2.0.11

In the dependencies for hoogle-5.0.14:
    haskell-src-exts-1.20.3 from stack configuration does not match >=1.18 && <1.20  (latest matching version is 1.19.1)
needed since hoogle is a build target.

Some different approaches to resolving this:

  * Set 'allow-newer: true' in /home/bradz/.stack/config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps in /home/bradz/.stack/global-project/stack.yaml:

Plan construction failed.

编辑:在/home/bradz/. stack /config.yaml中设置‘also更新: true’，然后执行堆栈安装切入点，也不起作用：

请告诉我怎么解决这个问题。

Answer 1

如果试图为atom包(或适用的依赖项)设置二进制文件，我可以使用不同的长期支持堆栈版本成功地安装依赖项。对于ghc-mod、hoogle、pointful和cabal install，我使用lts-9.21，而对hasktag、pointfree和brittany，我使用lts-11.22 =>。

stack --resolver lts-9.21 install ghc-mod hoogle pointful cabal-install

和

stack --resolver lts-11.22 install hasktags pointfree brittany

我希望这能帮到你。
