CPAN将模块安装到perl5中，而不是site_perl中 [英] CPAN installing modules into perl5 instead of site_perl

问题描述

我正在尝试将某些cpan模块临时安装到自定义文件夹（/ tmp / perl）中。所以我用...来修改构建安装基础...

I'm trying to do a temporary install of some cpan modules into a custom folder (/tmp/perl). So I have amending the build install base with...

o conf mbuildpl_arg "--install_base /tmp/perl"
o conf makepl_arg "INSTALL_BASE=/tmp/perl"

工作正常，将模块安装到现在该目录。我还将PERL5LIB设置为

Which works fine, the modules get installed into that directory now. I also set PERL5LIB with

  PERL5LIB=/tmp/perl/lib/5.14.2/:/tmp/perl/lib/site_perl/:/opt/perl/lib/5.14.2/:/opt/perl/lib/site_perl/:

注意，这只是暂时的，在将要销毁的虚拟服务器上。

Note, this is all just temporary, on a virtual server which will be destroyed.

我注意到，以前它会将模块安装到buildpath / lib /中。 5.14.2或buildpath / lib / site_perl

I note that, previously it would install modules into buildpath/lib/5.14.2 or buildpath/lib/site_perl

但是现在，将其安装模块安装到buildpath / lib / perl5

However now, its installing modules into buildpath/lib/perl5

我的理解是，核心perl模块最终出现在buildpath / lib / 5.14.2中，而非核心模块最终出现在buildpath / lib / site_perl中。

My understanding was that core perl modules ended up in buildpath/lib/5.14.2 and non-core modules ended up in buildpath/lib/site_perl.

安装到buildpath / lib / perl5中，是什么决定将其安装到perl5目录（而不是5.14.2或site_perl）中？

As this is installing into buildpath/lib/perl5, what decides to install into the perl5 directory as opposed to 5.14.2 or site_perl ?

推荐答案

除非您重写ExtUtils :: MakeMaker和Module :: Build通过环境变量（即 PERL_MM_OPT 和 PERL_MB_OPT 中的值）或命令行参数ents（例如 cpan 的 mbuildpl_arg 和 makepl_arg ）中的值将在构建时将其硬编码到Perl中。以下命令将为您显示这些位置（用于 .pm 和关联文件）：

Unless you override ExtUtils::MakeMaker and Module::Build through environment variables (i.e. values in PERL_MM_OPT and PERL_MB_OPT) or command line arguments (e.g. values in cpan's mbuildpl_arg and makepl_arg), locations hardcoded into Perl when it was built will be used. The following command will show you those locations (for .pm and associated files):

perl -V:'install(privlib|archlib|vendorlib|vendorarch|sitelib|sitearch)'

• installprivlib 包含Perl随附的纯Perl模块。


• installarchlib 与具有依赖于拱门或构建的组件的模块相同。


• installvendorlib 包含由发行版安装的纯Perl模块。


• installvendorarch 与带有Arch或build-dependent组件的模块相同


• installsitelib 包含您安装的 pure Perl模块。


• installsitearch 与带有依赖于建筑或构建的组件的模块相同。


• installprivlib contains the "pure Perl" modules that came with Perl.
• installarchlib is the same for modules with arch- or build-dependent components.
• installvendorlib contains the "pure Perl" modules installed by your distro.
• installvendorarch is the same for modules with arch- or build-dependent components.
• installsitelib contains the "pure Perl" modules installed by you.
• installsitearch is the same for modules with arch- or build-dependent components.

示例运行：

$ perl -V:'install(privlib|archlib|vendorlib|vendorarch|sitelib|sitearch)'
installprivlib='/usr/share/perl/5.14';
installarchlib='/usr/lib/perl/5.14';
installvendorlib='/usr/share/perl5';
installvendorarch='/usr/lib/perl5';
installsitelib='/usr/local/share/perl/5.14.2';
installsitearch='/usr/local/lib/perl/5.14.2';

&＃x20;

$ perl -V:'install(privlib|archlib|vendorlib|vendorarch|sitelib|sitearch)'
installprivlib='/home/ikegami/usr/perlbrew/perls/5.20.1t/lib/5.20.1';
installarchlib='/home/ikegami/usr/perlbrew/perls/5.20.1t/lib/5.20.1/x86_64-linux-thread-multi';
installvendorlib='';
installvendorarch='';
installsitelib='/home/ikegami/usr/perlbrew/perls/5.20.1t/lib/site_perl/5.20.1';
installsitearch='/home/ikegami/usr/perlbrew/perls/5.20.1t/lib/site_perl/5.20.1/x86_64-linux-thread-multi';

&＃x20;

>perl -V:"install(privlib|archlib|vendorlib|vendorarch|sitelib|sitearch)"
installprivlib='C:\progs\sp5280-x64\perl\lib';
installarchlib='C:\progs\sp5280-x64\perl\lib';
installvendorlib='C:\progs\sp5280-x64\perl\vendor\lib';
installvendorarch='C:\progs\sp5280-x64\perl\vendor\lib';
installsitelib='C:\progs\sp5280-x64\perl\site\lib';
installsitearch='C:\progs\sp5280-x64\perl\site\lib';
