perl - 这个 CPAN 错误是什么意思？

Question

我要安装IO::Uncompress::Gunzip ，所以我做

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

我得到

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.

如果我尝试安装 Compress::Raw::Bzip2和 Compress::Raw::Zlib我明白了

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
  Has already been unwrapped into directory /root/.cpan/build/Compress-Raw-Zlib-2.045-kBMzIh
Could not make: Unknown error
Running make test
  Can't test without successful make
Running make install
  Make had returned bad status, install seems impossible

cpan[13]> 

问题

有谁知道这些错误是什么意思，也许我该如何安装这些模块？

Answer 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)随后的错误可能是这种情况的副作用。
