我不确定要从这里出发。

编辑：我使用GHC版本7.4.1和Cabal版本1.14.0

以详细模式运行Cabal似乎没有给出任何提示，除了：

解决方案

原来是一个耗尽的内存问题，因为哈马尔怀疑。我可以通过在系统中添加一个1GB的交换文件来安装它（尽管速度很慢）：

  dd if = / dev / zero of = / swapfile bs = 1M count = 1024 
 mkswap / swapfile 
 swapon / swapfile 
  

显然EC2实例在默认情况下不带交换。

When I try to install it with cabal, I get

~$ cabal install ghc-mod

ExitFailure 9
hlint-1.8.33 depends on haskell-src-exts-1.13.5 which failed to install.

I'm not really sure where to go from here. How can I find out more about why it failed?

edit: I'm using GHC version 7.4.1 and Cabal version 1.14.0

Running Cabal in verbose mode doesn't seem to give any hints except:

...

World file is already up to date.

解决方案

It turned out to be a running-out-of-memory issue, as hammar suspected. I was able to get it to install (although it was painfully slow) by adding a 1GB swap file to the system:

dd if=/dev/zero of=/swapfile bs=1M count=1024
mkswap /swapfile
swapon /swapfile

Apparently EC2 instances come without swap by default.
