Haskell Stack无法安装easyrender

Question

我在Haskell堆栈上安装了GHC 8.0.2，我需要在项目上安装一定数量的软件包，其中一个是easyrender。

我使用以下命令安装它，该命令适用于所有其他软件包安装：

stack install easyrender

我得到以下输出：

easyrender-0.1.1.2: configure

由于Cabal似乎是一个问题，因此我尝试运行stack install Cabal ，但这没有任何作用。 引用的日志文件仅表示与输出相同的内容。

有想法吗？ 内森

这是easyrender软件包描述中的错误。 请注意，cabal-install的“ new-build”也遇到相同的问题。 请参阅我对此堆栈问题的评论： https : //github.com/commercialhaskell/stack/issues/3560#issuecomment-344075524

解决方法如Thomas的回答所述，也位于https://github.com/commercialhaskell/stack/issues/3560#issuecomment-343980627的问题中

下一个堆栈版本将发出有关这种情况的警告，这将减少将来的混乱。

不幸的是，easyrender没有问题跟踪器，它似乎只有一个黑客页面。 我已通过电子邮件发送给作者，要求他解决此问题。

cabal-install没有此类问题：

% cabal install easyrender
Resolving dependencies...
Downloading superdoc-0.1.2.5...
Configuring superdoc-0.1.2.5...
Building superdoc-0.1.2.5...
Installed superdoc-0.1.2.5
Downloading easyrender-0.1.1.2...
Configuring easyrender-0.1.1.2...
Building easyrender-0.1.1.2...
Installed easyrender-0.1.1.2

因此，我猜测这是堆栈以不同方式处理非简单构建的问题。 即，cabal-install似乎假定Cabal是setup.hs的依赖项，而堆栈则不是。

只是检查一下，我尝试过并且可能会产生相同的问题，但是将Cabal添加到easyrender.cabal setup-depends: easyrender.cabal其正常工作。
