There are several ways to install Perl modules from the Comprehensive Perl Archive Network on your Unix-based system. There is always more than one way to do things with Perl, and this is no different. Before embarking on any installation, download the module, unzip it and check out the documentation. Most modules are installed using the same method.

有多种方法可以在基于Unix的系统上从“综合Perl存档网络”安装Perl模块。 使用Perl总是有不止一种方法，这也不例外。 开始任何安装之前，请下载模块，解压缩并查看文档。 大多数模块使用相同的方法安装。

## 激活CPAN模块 **(** Activate the CPAN Module **)** ##

The simplest way to install [Perl ][Perl]modules to use the CPAN module itself. If you are the system administrator and want to install the module systemwide, you'll need to switch to your root user. To fire up the CPAN module, just get to your command line and run this:

安装[Perl][]模块以使用CPAN模块本身的最简单方法。 如果您是系统管理员，并且想要在系统范围内安装该模块，则需要切换到root用户。 要启动CPAN模块，只需进入命令行并运行以下命令：

If this is the first time you've run CPAN, it's going to ask you a series of questions—in most cases, the default answer is fine. Once you find yourself staring at the cpan> command prompt, installing a module is as easy as **install MODULE::NAME**. For example, to install the HTML::Template module you'd type:

如果这是您第一次运行CPAN，它将询问您一系列问题-在大多数情况下，默认答案很好。 一旦发现自己盯着cpan>命令提示符，安装模块就像**安装MODULE :: NAME**一样容易。 例如，要安装HTML :: Template模块，请输入：

CPAN should take it from there, and you'll wind up with the module installed in your Perl library.

CPAN应该从那里拿走它，然后您将获得安装在Perl库中的模块。

## 从命令行安装 **(** Installing from the Command Line **)** ##

Let's say you're on your system command line and you just want to install a module as quickly as possible; you can run the [Perl][Perl 1] CPAN module via command line Perl and install it in a single line:

假设您在系统命令行上，并且只想尽快安装模块； 您可以通过命令行Perl运行[Perl][Perl 1] CPAN模块并将其安装在一行中：

It's always advisable to download a module yourself, especially if you're having problems installing with CPAN. If you're on the command line, you can use something like **wget** to grab the file. Next, you'll want to unzip it with something like:

始终建议您自己下载一个模块，尤其是在使用CPAN安装时遇到问题时。 如果您使用的是命令行，则可以使用**wget之类的方法**来抓取文件。 接下来，您将需要使用以下方式将其解压缩：

This unzips the module into a directory and then you can go in and poke around. Look for the README or INSTALL files. In most cases, installing a module by hand is still pretty easy, though, although not as easy as CPAN. Once you've switched into the base directory for the module, you should be able to install it by typing:

这会将模块解压缩到目录中，然后您就可以四处浏览。 查找自述文件或安装文件。 尽管在大多数情况下，手动安装模块仍然很容易，尽管不如CPAN容易。 切换到模块的基本目录后，应该可以通过键入以下内容进行安装：
