我想安装IO::Uncompress::Gunzip，所以我做

perl -MCPAN -e shell 安装CPAN 安装IO :: Uncompress :: Gunzip

我得到了

cpan[11]> install IO::Uncompress::Gunzip

Shall I follow them and prepend them to the queue
of modules we are processing right now? [yes] 

...

问题

这些错误意味着什么，也许我可以如何安装这些模块？

Answer 1

我发现的第一个错误是/bin/sh: gcc: command not found。它正在尝试编译库的二进制部分，但无法找到您的编译器。您可能需要安装GCC。

很多（如果不是全部）后续错误都可能产生副作用。

Answer 2

这对我很有帮助，但是为了能够安装模块，我需要执行的另一个步骤是在重试安装[MODULE]之前执行干净的[MODULE]。

可能不需要提及这种环境的非新手，但我需要它。

这个CPAN错误是什么意思？
