CPAN Perl模块安装程序找不到tar文件

Question

在通过CPAN安装Perl模块时，我似乎遇到了一个配置问题，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 -l

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

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

这个问题似乎就在这里：

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似乎没有使用动态生成的/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，或者至少该信息没有到达tar命令。

有谁知道我如何在不需要手动安装的情况下修复这个机制？

Answer 1

编辑：

我又遇到了这个问题。我所需要做的就是像基思·布劳顿所说的那样释放一些记忆。

我遇到了同样的问题，试图找出这个问题的根本原因。我在这里列出我的发现，这样其他谷歌员工就不用花上几个小时就放弃了.

为我解决这个问题的只是简单的重新启动系统。

我试过的事情：

• 升级CPAN。如果出现“无法取消”错误消息，这也会失败。如果您使用cpan、"cpan -i CPAN“或"perl -MCPAN -e 'install CPAN'”来尝试它，我并不在意。我认为这些都不会解决问题，但当您开始谷歌搜索时，所有这些都被建议为可能的solutions.
• Replacing tar，它使用一个脚本记录其输入，以检查调用参数或cwd时是否不正确。这个剧本似乎从来没有被称为。即使在临时重命名/bin/tar.
• Checking CPAN/Tarzip.pm并在编写“不能取消”消息的代码附近添加打印行之后，“不能取消The”消息仍然是相同的。系统()调用似乎失败，tar (或我的调试代码中的ls )从未被调用过。

然后我决定重新启动，这是一个选择，因为这不是一个活的系统。之后，问题解决了，第一次尝试就安装了Perl模块。

其他意见：

，

• ，这个系统似乎能正常工作。您仍然可以连接到系统，您可以编辑文件，修改后仍在重新启动。我希望在Perl系统()调用开始失败之前，任何一个都会失败。
• 通过日志文件的快速扫描不会显示任何危险标志。

Answer 2

有时候，这可能只是由于缺乏可用内存而发生的。尝试关闭一些正在运行的服务，然后再试一次。

为我工作:-)

Answer 3

若要解决以下错误：

Couldn't untar WWW-Mechanize-1.72.tar

试着安装Archive::Tar

在centos 6.X：

yum install perl-Archive-Tar.x86_64
