为什么我的Perl程序会抱怨“无法在@INC中找到URI.pm"? [英] Why does my Perl program complain "Can't locate URI.pm in @INC"?

问题描述

我是Perl的新手.运行脚本时出现以下错误:

I'm new to Perl. I get the following error when I run a script:

Can't locate URI.pm in @INC (@INC contains: /usr/local/packages/perl_remote/5.6.1/lib/5.6.1/i86pc-solaris /usr/local/packages/perl_remote/5.6.1/lib/5.6.1 /usr/local/packages/perl_remote/5.6.1/lib/site_perl/5.6.1/i86pc-solaris /usr/local/packages/perl_remote/5.6.1/lib/site_perl/5.6.1 /usr/local/packages/perl_remote/5.6.1/lib/site_perl .) at (eval 2) line 3.

Compilation failed in require at txotf_0_install.pl line 35.
BEGIN failed--compilation aborted at txotf_0_install.pl line 35.

这可能是什么原因，以及如何使脚本正常工作.任何帮助将不胜感激.

What could be the possible reasons of this and how do I get the script to work. Any help will be appreciated.

推荐答案

• 可能您没有安装URI.它可能未保存在计算机上的任何位置，或者可能已安装"在某个位置.

  • Possibly you do not have URI installed. It might not be saved anywhere on your machine, or it might be "installed" in a location.

    • 如果尚未安装，则需要从CPAN安装.
    • 如果将其保存到计算机中，则只需让系统知道从何处获取它.

    如果必须从CPAN安装它，则可能需要管理员权限才能将其放入列出的目录中.但是CPAN允许您将其安装到用户目录，因此您仍然可以安装它.

    If you have to install it from CPAN, you likely need administrator privileges to put it in the listed directories. But CPAN will allow you to install it to a user directory, so you can still install it.

    因此，如果您不能在@INC中列出的目录中安装该模块，则可以采用多种方法.

    So if you can't install the module in the directories listed in @INC, then there are the various ways.

    1. Perl 5读取一个名为PERL5LIB的环境变量.该数组"中的任何目录都将前缀到@INC.因此，$ENV{PERL5LIB}目录结构中的任何内容都将优先于任何系统目录. (请参见此处)

    1. Perl 5 reads a environment variable called PERL5LIB. Any directory in that "array" will be prepended to @INC. So anything in the directory structure of $ENV{PERL5LIB} will be preferred to any system directory. (see here)

    另一种实现方法是根据 script . use lib编译指示还将指定的目录插入到@INC中. (请参见 lib )

    Another way you can do this is per script. The use lib pragma also inserts specified directories into @INC. (see lib)

    use lib '/path/to/URI/module';
    use URI;
    

  • 最后一种方法是，您可以每次运行 进行操作.您可以在命令行perl -I/path/to/URI/module -e 1上使用-I开关运行perl(请参见 perlrun )

  • The final way, you can do it per run. You can run perl with the -I switch on the command line perl -I/path/to/URI/module -e 1 (see perlrun)
