如何找到Perl模块的安装位置? [英] How can I find out where a Perl module is installed?

问题描述

如何按名称获取已安装的Perl模块的路径， 例如Time::HiRes?

How do get the path of a installed Perl module by name, e.g. Time::HiRes?

我想要这个只是因为我必须在SGE Grid Engine系统的不同节点上运行我的perl脚本.有时，甚至可以使用其他用户名运行.

I want this just because I have to run my perl script on different nodes of a SGE Grid Engine system. Sometimes, even run as other username.

我可以使用CPAN.pm为自己安装软件包，但是对于没有chmod 666文件夹的其他用户来说，安装它并不是那么容易.

I can use CPAN.pm to install packages for myself, but it is not so easy to install for other users without chmod 666 on folders.

推荐答案

注意:此解决方案建议使用必须自行创建的(自授权)实用程序 >下载.虽然它提供了我认为有用的功能，但并非所有人都可以选择先安装第三方解决方案.

Note: This solution proposes use of a (self-authored) utility that you must download. While it offers what I believe to be helpful features, installing a third-party solution first is not an option for everyone.

我已经创建> whichpm (跨平台CLI (Linux，macOS，Window)，它按模块(软件包)名称查找已安装的Perl模块，并可以选择报告有关它们的信息，包括检测意外重复.

I've created whichpm, a cross-platform CLI (Linux, macOS, Window) that locates installed Perl modules by module (package) name, and optionally reports information about them, including detection of accidental duplicates.

示例

# Locate the Data::Dumper module.
$ whichpm Data::Dumper
/usr/lib/perl/5.18/Data/Dumper.pm

# Locate the Data::Dumper module, and also print
# version information and core-module status.
$ whichpm -v Data::Dumper
Data::Dumper    2.145   core>=5.005 /usr/lib/perl/5.18/Data/Dumper.pm

# Locate the Data::Dumper module and open it in your system's default text
# editor.
$ whichpm -e Data::Dumper

# Look for accidental duplicates of the Foo::Bar module.
# Normally, only 1 path should be returned.
$ whichpm -a Foo::Bar
/usr/lib/perl/5.18/Foo/Bar.pm
./Foo/Bar.pm

# Print the paths of all installed modules.
$ whichpm -a

安装

先决条件:已安装 Perl v5.4.50或更高版本的 Linux ， macOS 或 Windows .

使用 Node.js 或 io.js ，如下安装包:

[sudo] npm install whichpm -g

手动安装(macOS和Linux)

• 将 CLI 下载为whichpm.
• 使用chmod +x whichpm将其设为可执行文件.
• 将其移动或符号链接到$PATH中的文件夹，例如/usr/local/bin(OSX)或/usr/bin(Linux).

Manual installation (macOS and Linux)

• Download the CLI as whichpm.
• Make it executable with chmod +x whichpm.
• Move it or symlink it to a folder in your $PATH, such as /usr/local/bin (OSX) or /usr/bin (Linux).
