我想在Ubuntu 20.04上安装Cabal 3.4.0.0。
$ sudo apt install cabal-install
$ cabal --version
cabal-install version 2.4.0.0
$ sudo cabal update
$ sudo cabal install Cabal cabal-install
...

cabal: Missing dependency on a foreign library:
* Missing (or bad) header file: zlib.h
* Missing (or bad) C library: z
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the
library file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.

错误提示如下:
通常可以通过安装提供该库的系统软件包来解决此问题(您可能需要安装"-dev"版本)。
在Ubuntu 20.04上我应该如何安装这个软件包呢?
apt-cache
非常有用。尝试使用“apt-cache search zlib”命令。请参见相关SE问题。 - jpmarinier
