如何更新CPAN perl模塊

Question

我正在嘗試安裝一些perl模塊，但每次顯示此消息時

  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.

我試過這樣做

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

但結果是

版本仍然是1.960001。

適用於使用Ubuntu 14.04的BANANA Pi單板計算機。

Answer 2

1. 從此頁面http://metacpan.org/pod/CPAN下載CPAN模塊

2. tar zxf CPAN-2.00.tar.gz它（ tar zxf CPAN-2.00.tar.gz ），cd進入目錄並運行

    perl Makefile.PL make test sudo make install 

編輯：如果它打破了在其中創建::的路徑，那么您的文件系統類型可能不支持文件名中的這些字符

要查看文件系統類型，請運行不帶任何參數的mount ，並顯示所有已安裝的文件系統及其類型

錯誤Can't write-open blib/man3/CPAN::Admin.3pm似乎表明存在文件系統問題，但是在rw模式下的ext4聽起來不錯。 從CPAN-2.00目錄中嘗試此操作

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