CPAN Perl模块安装程序没有找到tar文件

导读：通过CPAN安装Perl模块时,我似乎有一个配置问题,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 -ltotal 240-rw-r--r-- 1 root root 105464 Feb 20 11:39 CHECKSUMS-rw-r--r-- 1 root root 9223 Ap

通过CPAN安装Perl模块时,我似乎有一个配置问题,我不知道如何纠正它：

[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,可以在这里找到一个新的目录：

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

如果我从shell里面运行相同的命令,我会得到一些更多的信息：

Failed during this command:

在我看来,$newdir没有被动态生成的/root/.cpan/build/JESSE-DGrTh_/或/root/.cpan/build/JESSE-KjCEMS/或任何系统生成的东西或至少这些信息被更新没有得到tar命令

有没有人知道如何修复机制,而无需使用手动安装？

解决方法

编辑：

我再次遇到这个问题.所有我需要做的都是释放一些像Keith Broughton所建议的记忆.

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

什么解决了我的只是重新启动系统.

我试过的东西

>升级CPAN.这也将失败,并显示“无法解压缩”错误消息.如果您尝试使用cpan shell,“cpan -i CPAN”或“perl -MCPAN -e”安装CPAN“,这并不重要.我没有想到任何这些都可以解决问题,但是当您开始搜索时,所有这些都是可能的解决方案.
>使用记录其输入的脚本替换tar,以便在调用时检查其中一个参数或cwd是否不正确.脚本从来没有被称为似乎.即使临时重命名/ bin / tar,“无法解密”的消息仍然是一样的.
>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,tar(或调试代码中的ls)从未被调用.

然后我决定重新启动,这是一个选项,因为这不是一个现场系统.之后,问题消失了,首先尝试安装Perl模块.

其他意见：

>系统似乎工作正常,其余的.您仍然可以连接到系统,您可以编辑文件,修复仍然在重新启动后.在Perl系统()调用开始失败之前,我会期望其中的任何一个失败.>通过日志文件的快速扫描不显示任何红旗.
