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.

我试过这样做

install CPAN
reload cpan

同

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

Answer 1

以下程序

1. kuz1@banana:~$ sudo perl -MCPAN -e shell
2. cpan[1]> install CPAN
3. cpan[2]> reload cpan

适用于使用Ubuntu 14.04的BANANA Pi单板计算机.

Answer 2

1. 从这个页面下载 CPAN 模块http://metacpan.org/pod/CPAN

2. 解压它 ( 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：如果它破坏了用 :: 在其中创建路径，那么您的文件系统类型可能不支持文件名中的这些字符

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

该错误Can't write-open blib/man3/CPAN::Admin.3pm似乎表明存在文件系统问题，但 rw 模式下的 ext4 听起来不错。从CPAN-2.00目录中试试这个

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