Question

我正在尝试使用Cabal安装用haskell编写的图表包。运行cabal install diagrams

时出现以下错误

[~]$ cabal install diagrams

Failed to install bytes-0.15.2
cabal: Error: some packages failed to install:
active-0.2.0.8 depends on bytes-0.15.2 which failed to install.
bytes-0.15.2 failed during the building phase. The exception was:
ExitFailure 1
diagrams-1.3.0.1 depends on bytes-0.15.2 which failed to install.
diagrams-contrib-1.3.0.8 depends on bytes-0.15.2 which failed to install.
diagrams-core-1.3.0.6 depends on bytes-0.15.2 which failed to install.
diagrams-lib-1.3.1.1 depends on bytes-0.15.2 which failed to install.

force-layout-0.4.0.3 depends on bytes-0.15.2 which failed to install.
linear-1.20.4 depends on bytes-0.15.2 which failed to install.

我使用命令分别使用cabal安装了字节-0.15.2 cabal install bytes。怎么可能出错？当安装图表时，cabal似乎不必要地再次尝试安装字节。

如何解决这些编译错误？

我在Ubuntu 14.04上使用ghc版本7.6.3和cabal版本1.22.7.0运行

如何在安装图表时修复这些cabal安装错误？
