【问题描述】:
我正在尝试在 OS X 上安装图表。下载它时,我收到这种错误消息:
Building linear-1.20.4...
Failed to install linear-1.20.4
Build log ( /Users/Max/.cabal-sandbox/logs/linear-1.20.4.log ):
然后在一些成功的链接包之后的一段时间:

有人知道怎么解决吗?
我的 gtk 和 cabal 都是最新的。
谢谢你:)
【问题讨论】:
-
您的 ghc 版本可能太低,所以
DeriveGeneric语言扩展无法正常工作。试试 stack build tool,它会为你安装正确版本的 ghc。 -
看起来
Eq1和朋友是由transformers(或者可能是transformers-compat)包提供的。它选择了transformers和transformers-compat的哪个版本? -
(特别是,如果您使用的是
--allow-newer,这可能会导致这里出现问题。) -
我在 debian 8 上遇到了同样的问题。ghc 版本 7.6.3
