Question

我有Ubuntu 14.04LTS。我从http://www.haskell.org/ghc/download_ghc_7_8_3#x86_64linux下载了最新的ghc-7.8.3并将其安装到/usr/local。

然后我将cabal更新为版本1.20.0.3。

我在我的终端输入了cabal install QuickCheck，然后得到了：

cabal: Error: some packages failed to install:
QuickCheck-2.7.5 depends on tf-random-0.5 which failed to install.
tf-random-0.5 failed during the building phase. The exception was:
ExitFailure 1

顺便说一句，我之前已通过haskell-platform安装了ghc-7.6.3 apt-get。

我记得在设置ghc-7.8时有类似的问题。它与新的cabal有关，它与安装了旧版本的库不兼容（但它没有给出正确的问题原因。

无论如何，我认为重新安装有问题的软件包

cabal install random --reinstall --force-reinstalls

设置它，以便cabal install tf-random成功。

cabal报告＆＃34; / usr / bin / ld：找不到-lHSrandom-1.0.1.1-ghc7.8.3＆＃34;
