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.

You might want to try
install CPAN
reload cpan
to both upgrade CPAN.pm and run the new version without leaving
the current session.

download CPAN module from this page http://metacpan.org/pod/CPAN
untar it (
tar zxf CPAN-2.00.tar.gz), cd into the directory and runperl Makefile.PL make test sudo make install
从这个页面下载 CPAN 模块http://metacpan.org/pod/CPAN
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
edit: if it breaks making a path with :: in it then perhaps your filesystem type does not support these characters in a filename
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
To see the filesystem type, run mountwithout any parameters and all the mounted filesystems with their types will be shown
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
The error Can't write-open blib/man3/CPAN::Admin.3pmseems to suggest a filesystem problem, but ext4 in rw mode sounds alright. Try this from the CPAN-2.00directory
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 $!;'

The following procedure
以下程序
kuz1@banana:~$ sudo perl -MCPAN -e shellcpan[1]> install CPANcpan[2]> reload cpan
kuz1@banana:~$ sudo perl -MCPAN -e shellcpan[1]> install CPANcpan[2]> reload cpan
works for me on the BANANA Pi Single-Board Computer with Ubuntu 14.04.
在装有 Ubuntu 14.04 的 BANANA Pi 单板计算机上为我工作。
