如何更新CPAN perl模块

Question

我正在尝试安装一些perl模块，但每次显示此消息时

  New CPAN.pm version (v2.00) available.
  [Currently running version is v1.960001]
  You might want to try
    install CPAN
    reload cpan
  to both upgrade CPAN.pm and run the new version without leaving
  the current session.

我试着去做

install CPAN
reload cpan

使用

pi@raspbmc:~$ sudo perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.960001)
Enter 'h' for help.

cpan[1]> install CPAN

但结果是

Going to read '/root/.cpan/sources/authors/01mailrc.txt.gz'
............................................................................DONE
Going to read '/root/.cpan/sources/modules/02packages.details.txt.gz'

版本仍然是1.960001。

Answer 1

1. 从此页面下载CPAN模块http://metacpan.org/pod/CPAN
2. untar it (tar zxf CPAN-2.00.tar.gz)，cd进入目录并运行

perl Makefile.PL make test sudo make install

编辑:如果中断在其中使用:：创建路径，则可能您的文件系统类型不支持在文件名中使用这些字符

要查看文件系统类型，请不带任何参数运行mount，将显示所有已挂载的文件系统及其类型

错误Can't write-open blib/man3/CPAN::Admin.3pm似乎表明文件系统有问题，但是rw模式下的ext4听起来没问题。尝试从CPAN-2.00目录执行此操作

perl -e 'open($f,">blib/man3/CPAN::thisisatest") || die $!;'
