如何安装 perl Logger 模块

Question

我是 perl 的菜鸟。搜索“如何安装 perl 模块”我确实安装了 cpan 并尝试了以下操作：

sudo cpan install Logger

但收到：

Going to read '/Users/steve/.cpan/Metadata'
  Database was generated on Wed, 09 Oct 2013 06:53:03 GMT
Warning: Cannot install Logger, don't know what it is.
Try the command

    i /Logger/

to find objects with matching identifiers.

所以我也试过了：

cpan[1]> i Logger
Going to read '/Users/steve/.cpan/Metadata'
  Database was generated on Wed, 09 Oct 2013 06:53:03 GMT
No objects found of any type for argument Logger

以下是一些进口：

use TDScli;
use Logger;

Answer 1

CPAN 上没有名为Logger 的模块。它们都被称为“Logger::Something”或“Something::Logger”。如果您的项目正在使用一个名为“Logger”的模块，那么它就不是来自 CPAN。您需要找出应该从何处获取该模块。
