CPAN Perl模块安装程序找不到tar文件

Question

通过CPAN安装Perl模块时似乎有配置问题,我不知道如何纠正它:

[root@ip JESSE]# pwd
/root/.cpan/sources/authors/id/J/JE/JESSE

[root@ip JESSE]# ls -l

[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":
Couldn't untar WWW-Mechanize-1.72.tar

tar.gz文件确实是未压缩的,可以在新目录中找到:

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

如果我从shell内部运行相同的命令,我会得到更多信息:

在我看来,$ newdir没有使用动态生成的/root/.cpan/build/JESSE-DGrTh_/ 或者/root/.cpan/build/JESSE-KjCEMS/系统生成的任何内容进行更新, 或者至少该信息没有进入tar命令

有谁知道我怎么能修复机制而不必诉诸手动安装？

Answer 1

编辑:

我又遇到了这个问题.我需要做的就是像Keith Broughton所建议的那样释放一些记忆.

我遇到了同样的问题,并试图找到这个问题的根本原因.我在这里列出了我的发现,所以其他Google员工不必花费几个小时才能放弃......

为我解决的只是重启系统.

我试过的事情:

• 升级CPAN.这也会因"无法解压"错误消息而失败.如果你尝试使用cpan shell,"cpan -i CPAN"或"perl -MCPAN -e'安装CPAN'",我无所谓.我认为其中任何一个都不会解决问题,但是当你开始谷歌搜索所有这些都被建议作为可能的解决方案.
• 用脚本替换tar,该脚本记录其输入以检查其中一个参数或cwd在调用时是否不正确.似乎从未调用过脚本.即使在临时重命名/ bin/tar之后,"无法解压"消息仍然是相同的.
• 检查CPAN/Tarzip.pm并在写入"无法解压缩"消息的代码附近添加打印行.似乎system()调用失败,并且从不调用tar(或我的调试代码中的ls).

然后我决定重新启动,这是一个选项,因为这不是一个实时系统.之后问题就消失了,首先尝试安装Perl模块.

其他观察:

• 该系统似乎对其余部分工作得很好.您仍然可以连接到系统,您可以编辑文件,重启后仍然存在修改.我希望在Perl system()调用开始失败之前很久就会失败.
• 快速扫描日志文件不会显示任何红色标记.

Answer 2

有时这可能仅仅因为缺乏可用内存而发生.尝试关闭一些正在运行的服务,然后重试.

为我工作:-)

Answer 3

意外的是：分区已满。删除一些文件。
