Eclipse 日食不发生'；行不通

我正试图在Mac OS Yosemite 10.10.5上的Eclipse版本：Mars发行版（4.5.0）上安装EclipseFP

虽然出现了Haskell透视图，但Haskell语言的任何特殊功能都不起作用（语法高亮显示、hoogle搜索等等）

以下是我的Eclipse首选项：

问题似乎是，并不是所有必要的包都可以编译（但确定这是根本原因）

例如，当我在Haskell helper可执行文件中按下“从Hackage安装”按钮时，它正试图编译它，但由于

ghc-pkg-lib-0.3

，它失败了：

有人能帮我一下吗？

因为EclipseFP和BuildWrapper经常发生变化，他们已经停止支持这两个项目，应该使用一些Leskah和IDE

这不是你想要的，但你试过leksah吗？这是一个原生的Haskell IDE。

ghc pkg lib

似乎没有为其依赖项指定上限，而且您正在获得一个更新版本的

Cabal

，它无法成功构建。考虑添加一个显式约束，如代码> Cabar在GITHUB上找到了PACKAG.HS的更新版本，并成功地构建了这个模块，但是在下一个模块中被破坏了…在github上还发现EclipseFP不再维护…是的，我安装了Leksah，但似乎它的功能更少…作为以前的EclipseFP用户，我现在切换到emacs，它可能对haskell有最好的支持，目前有各种插件可以自动完成，给出类型提示等。。
