我究竟做错了什么？我需要安装perl吗？终端中的 which perl 返回 perl 的安装目录。这是否意味着 perl 不是问题所在？我不知道要提供什么其他细节，但如果有人能指出我正确的方向，我将非常感激。

Answer 1

Perl 附带了大量扩展其功能的标准库。但是CPAN还提供了数千个其他扩展库。

File::Slurp是一个 CPAN 模块。它不是标准 Perl 发行版的一部分，因此您需要单独安装它。

幸运的是，Ubuntu 打包了大量的 CPAN 模块，并从其标准存储库中提供它们。因此，要安装它，您只需运行：

$ sudo apt-get install libfile-slurp-perl
