【问题描述】：
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
...
Starting zlib-0.6.2.3
Failed to install zlib-0.6.2.3
Build log ( /root/.cabal/logs/ghc-8.6.5/zlib-0.6.2.3-93Wbo8gIIzI9bg4p2MsNUF.log ):
cabal: Entering directory '/tmp/cabal-tmp-126381/zlib-0.6.2.3'
Configuring zlib-0.6.2.3...
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.

cabal-install-3.4.0.0-3glzV3hM64DLoOfz3dHKsn depends on cabal-install-3.4.0.0
which failed to install.

zlib-0.6.2.3-93Wbo8gIIzI9bg4p2MsNUF failed during the configure step. The
exception was:
ExitFailure 1
错误提示：
这个问题通常可以通过安装系统包来解决 提供这个库（你可能需要“-dev”版本）。
如何在 Ubuntu 20.04 上安装此软件包？
【问题讨论】：
-
sudo apt-get install zlib1g-dev -
@WillemVanOnsem 谢谢，这行得通！您是如何找到这些信息的（这样我下次可以自己找到）？
-
命令
apt-cache很有用。尝试“apt-cache search zlib”。见related SE question -
@WillemVanOnsem 你应该发表你的评论作为答案，这样它才能被接受。
