【问题描述】：

我想安装IO::Uncompress::Gunzip，所以我愿意

perl -MCPAN -e 外壳安装 CPAN 安装 IO::Uncompress::Gunzip

我明白了

cpan[11]> install IO::Uncompress::Gunzip
Running install for module 'IO::Uncompress::Gunzip'
Running make for P/PM/PMQS/IO-Compress-2.046.tar.gz
  Has already been unwrapped into directory /root/.cpan/build/IO-Compress-2.046-d_Y9xt
---- Unsatisfied dependencies detected during ----
----       PMQS/IO-Compress-2.046.tar.gz      ----
    Compress::Raw::Zlib [requires]
    Compress::Raw::Bzip2 [requires]
Shall I follow them and prepend them to the queue
of modules we are processing right now? [yes] 

...

Result: FAIL
Failed 78/86 test programs. 35/328 subtests failed.
make: *** [test_dynamic] Error 255
  PMQS/IO-Compress-2.046.tar.gz

如果我尝试安装 Compress::Raw::Bzip2 和 Compress::Raw::Zlib 我会得到

cpan[12]> install Compress::Raw::Zlib
Running install for module 'Compress::Raw::Zlib'
Running make for P/PM/PMQS/Compress-Raw-Zlib-2.045.tar.gz

cpan[13]>

问题

谁知道这些错误是什么意思，也许我可以如何安装这些模块？

【问题讨论】：

标签： perl cpan

【解决方案1】：

我能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，但找不到您的编译器。您可能需要安装 GCC。

很多（如果不是全部）后续错误可能是由此产生的副作用。

【解决方案2】：

这对我很有帮助，但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]，但此处没有提到我需要执行的一个步骤。

对于这种环境的非新手来说，可能不需要提及，但我需要它。
