如何安装“帽子”

Question

我正在尝试获取Hat调试器。当我尝试：

cabal install hat或cabal install hat -v

最后我得到了：

configure: error: in `/tmp/terminfo-0.4.0.0-17745/terminfo-0.4.0.0':
configure: error: curses headers could not be found, so this package cannot be built
See `config.log' for more details
Failed to install terminfo-0.4.0.0
cabal: Error: some packages failed to install:
haskeline-0.7.1.3 depends on terminfo-0.4.0.0 which failed to install.
hat-2.8.0.0 depends on terminfo-0.4.0.0 which failed to install.
terminfo-0.4.0.0 failed during the configure step. The exception was:
ExitFailure 1

所以我试着解决问题：

cabal install terminfo

并得到：

configure: error: in `/tmp/terminfo-0.4.0.0-18341/terminfo-0.4.0.0':
configure: error: curses headers could not be found, so this package cannot be built
See `config.log' for more details
Failed to install terminfo-0.4.0.0
cabal: Error: some packages failed to install:
terminfo-0.4.0.0 failed during the configure step. The exception was:
ExitFailure 1

如何安装Hat？

Answer 1

假设您是在某种Linux上，应该有一个像"libncurses5-dev“这样的系统包(这是Ubuntu中的名称)，您可以安装这个包来获取诅咒头。

Answer 2

一旦你在系统上安装了诅咒，

cabal install terminfo --extra-include-dirs=/path/to/curses/include --extra-lib-dirs=/path/to/curses/lib

当然，要适当地替换/path/to/curses。

您的平台的包管理器也可以直接安装终端，也可以使用单独的包管理器，即Nix软件包管理器 (这在Haskellers中特别流行)。
