如何告诉CPAN安装所有依赖项?

How do I tell CPAN to install all dependencies?

我尝试在cpan中设置这些设置:

I tried setting these in cpan:

cpan> o conf prerequisites_policy follow
cpan> o conf commit

我仍然不得不回答"y"两次(但比以前感觉要少).

I still had to answer "y" a couple of times (but fewer than before it feels like).

有没有一种方法可以使它始终进行安装?我想让它无人值守.

Is there a way to get it to always go ahead and install? I want to make it unattended.

似乎我希望一个标志始终信任CPAN做正确的事，如果它建议一个答案，我想关注它(总是在问到问题时按 Enter ).

It would seem that I want a flag to always trust CPAN to do the right thing, and if it suggests an answer I would like to follow it (always hit Enter when it asks something).

推荐答案

这是使这些更改永久生效的唯一方法，包括自动首次CPAN配置:

Here is the one-liner making these changes permanent including automatic first-time CPAN configuration:

perl -MCPAN -e 'my $c = "CPAN::HandleConfig"; $c->load(doit => 1, autoconfig => 1); $c->edit(prerequisites_policy => "follow"); $c->edit(build_requires_install_policy => "yes"); $c->commit'

或将其与local::lib模块组合以用于非特权用户:

Or combine it with local::lib module for non-privileged users:

perl -MCPAN -Mlocal::lib=~/perl5 -e 'my $c = "CPAN::HandleConfig"; $c->load(doit => 1, autoconfig => 1); $c->edit(prerequisites_policy => "follow"); $c->edit(build_requires_install_policy => "yes"); $c->commit'

在使用CPAN Shell或其他任何东西之前先运行它.

Run it before using the CPAN shell or whatever.
