如何升级从CPAN安装的perl模块？

Question

在cpan shell中,只有/ regexp /或所有模块都可以升级,如果我想升级只由CPAN安装的模块,该怎么办？

Answer 1

我建议你使用cpanm"family"脚本进行perl模块管理.

安装cpanm

• 跳过这个,如果你已经拥有它
• curl -L http://cpanmin.us | perl - --sudo App::cpanminus
• 如果你在freebsd上,你可以使用而不是curl命令fetch(参见:man fetch)

升级 cpanm

• 如果您现在安装它,请跳过此步骤
• cpanm --self-upgrade --sudo

安装cpan-outdated

• cpanm App::cpanoutdated
• cpan-outdated命令与CPAN(r)相同,但IMO最好在shell中使用

例如,只有我的笔记本给出的结果如下:

marvin:~ jomo$ cpan-outdated
S/SM/SMUELLER/Attribute-Handlers-0.93.tar.gz
D/DR/DROLSKY/Class-Load-0.20.tar.gz
D/DR/DROLSKY/DateTime-TimeZone-1.47.tar.gz
... etc

运行cpan-outdated和升级模块

• cpan-outdated -p | cpanm

变化

如果要查看更改内容(更改日志),可以尝试安装cpan-listchanges

• cpanm App::cpanlistchanges
• 并使用它:cpan-listchanges Plack - 也看看普拉克在本地和最新的CPAN之间发生了什么变化

只运行以下命令就可以满足您的要求.

cpan> upgrade

Answer 3

$ cpan Module

和

cpan> install Module 

如果有更新的版本可用，将升级，如果您已经有最新版本，则不执行任何操作。
