perl - CPAN Perl模块安装程序找不到tar文件

通过CPAN安装Perl模块时，似乎出现配置问题，我不知道如何纠正它:

[root@ip JESSE]# pwd

[root@ip JESSE]# which tar
/bin/tar

[root@ip JESSE]# which gzip
/bin/gzip

问题似乎在这里:

Uncompressed /root/.cpan/sources/authors/id/J/JE/JESSE/WWW-Mechanize-1.72.tar.gz successfully
Using Tar:/bin/tar xvf "WWW-Mechanize-1.72.tar":

tar.gz文件确实未经压缩，可以在新目录中找到:

/root/.cpan/build/JESSE-KjCEMS/WWW-Mechanize-1.72.tar

如果我从 shell 程序内部运行相同的命令，则会得到更多信息:

在我看来，$ newdir不会使用动态生成的/root/.cpan/build/JESSE-DGrTh_/或/root/.cpan/build/JESSE-KjCEMS/或系统生成的任何内容进行更新，或者至少信息没有到达tar命令

有谁知道我可以在无需手动安装的情况下修复该机制？

最佳答案

编辑:

我又遇到了这个问题。我所需要做的就是释放一些内存，如Keith Broughton建议的那样。

我遇到了同样的问题，并试图找到此问题的根本原因。我在这里列出我的发现，因此其他Google员工不必花几个小时就可以放弃...

为我解决的只是简单地重新启动系统。

我尝试过的事情:

升级CPAN。这也将失败，并显示“无法解压缩”错误消息。不管您使用cpan shell，“cpan -i CPAN”还是“perl -MCPAN -e'install CPAN'”进行尝试，都没有关系。我认为这些方法都不能解决问题，但是当您开始使用Google搜索时，建议将所有这些方法作为可能的解决方案。

用记录日志其输入的脚本替换tar，以检查调用时参数或cwd之一是否不正确。似乎从未调用过该脚本。即使暂时重命名/bin/tar，“无法解压缩”消息仍然相同。

检查CPAN/Tarzip.pm，并在写“无法解压”消息的代码附近添加打印行。似乎system()调用失败，并且从未调用过tar(或我的调试代码中的ls)。

然后我决定重新启动，这是一个选择，因为这不是实时系统。此后，问题消失了，并且第一次尝试安装了Perl模块。

其他观察:

该系统似乎可以正常工作。您仍然可以连接到系统，可以编辑文件，重新启动后仍可以进行修改。我希望其中任何一个在Perl system()调用开始失败之前都会失败很长时间。

快速浏览日志文件不会显示任何红色标记。
