perl - 无法从 CPAN (Perl) 安装

Question

我正在尝试安装 perlcc module使用 cpan:

cpan[1]> install perlcc
Reading '/home/iuser/.local/share/.cpan/Metadata'
  Database was generated on Fri, 08 Sep 2017 12:41:02 GMT
Warning: Cannot install perlcc, don't know what it is.
Try the command

    i /perlcc/

to find objects with matching identifiers.

cpan[2]> i /perlcc/
No objects found of any type for argument /perlcc/

cpan[3]> 

为什么即使搜索页面显示有此模块，但仍未安装？如何解决这个问题？

Answer 1

perlcc 不是模块。它是一个命令行可执行文件。

查看您链接到的页面:

……它是 Perl 本身的一部分。

使用 Google 搜索 perlcc 出现了 this page，上面写着:

perlcc has been removed from Perl effective Perl 5.10. It and the underlying modules have always been out of date, broken and unmaintained.

因此您可以安装旧版本的 Perl(perlbrew 可能会有所帮助)以访问它。

该页面还说:

Reini Urban has since fixed it and has been maintaining it as part of B::C

因此您可以考虑安装它。
