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：

有谁知道如何解决它？

我的 gtk 和 cabal 都是最新的。

您在该版本的线性中遇到了与transformers库的某些版本相关的错误。

评论指出：“已经在 4a2aab7 中修复，还没有在 Hackage 上。与此同时，使用变形金刚 > 0.3 或变形金刚兼容 < 0.5”
