perl - Linux:如何安装 DBD::Pg 模块？

Question

Postgres 数据库已经安装。我没有使用系统 perl 我在“/srv/data203806/Migration/CPAN/localperl/bin”中安装了另一个 perl。当我尝试安装时，它要求提供 pg_config 的路径:

[root1@frmrszvwb023 bin]# ./cpan install DBD::Pg
Reading '/root/.cpan/Metadata'
  Database was generated on Fri, 07 Mar 2014 03:53:02 GMT
Running install for module 'DBD::Pg'
Running make for T/TU/TURNSTEP/DBD-Pg-3.0.0.tar.gz
Checksum for /root/.cpan/sources/authors/id/T/TU/TURNSTEP/DBD-Pg-3.0.0.tar.gz ok

  CPAN.pm: Building T/TU/TURNSTEP/DBD-Pg-3.0.0.tar.gz

    Configuring DBD::Pg 3.0.0
    Path to pg_config?
    No POSTGRES_HOME defined, cannot find automatically
    Warning: No success on command[/srv/data203806/MUXmh-Migration/CPAN/localperl/bin/perl Makefile.PL]
    'YAML' not installed, will not store persistent state
      TURNSTEP/DBD-Pg-3.0.0.tar.gz
      /srv/data203806/MUXmh-Migration/CPAN/localperl/bin/perl Makefile.PL -- NOT OK
    Running make test
      Make had some problems, won't test
    Running make install
      Make had some problems, won't install
    Could not read metadata file. Falling back to other methods to determine prerequisites

请帮我安装 DBD::Pg？如何获取 pg_config 的路径？

刚遇到这个问题，在 Ubuntu 16.04 Xenial 上你要找的包是:

apt-get install libdbd-pg-perl
