cpan忽略makepl_arg和mbuild_arg [英] cpan ignores makepl_arg and mbuild_arg

问题描述

我按照该问题获得最高投票的答案中的说明进行操作如何将CPAN模块安装到本地目录中？，基本上说我可以配置CPAN以使用以下方式在本地安装模块：

I followed the instructions in the most voted answer to this question How can I install a CPAN module into a local directory?, which basically says that I can configure CPAN to install modules locally with:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

cpan> o conf mbuild_arg '--install_base /mydir/perl'
cpan> o conf commit

但是，当我尝试

% cpan
% install List::Gen

我的安装失败（看来CPAN仍然尝试在系统路径上安装）。为什么？

My installation fails (it looks like CPAN still tries to install on a system path). Why?

推荐答案

应为 mbuildpl_arg ，不是 mbuild_arg

o conf mbuild_arg ''                              # Fix past error
o conf mbuildpl_arg '--install_base /mydir/perl'  # Specify install base
o conf commit                                     # Save changes
