[Ubuntu]無法安裝Cpan安裝::線程

Question

我現在面臨一些問題，現在谷歌並沒有幫助我太多。我想使用需要線程的perl程序，但這給我很難。我目前使用Perl 5.10.1，它不支持多線程，但通常我下面粘貼的命令應該沒有任何問題地安裝。我願意成爲好幫手的回報。

所以我已經試過這樣：

sudo su - 
cpan 
install shared::thread 

（高錯位）輸出：

root@noc:~# sudo su - root@noc:~# cpan Terminal does not support 
AddHistory. 

cpan shell -- CPAN exploration and modules installation (v1.9402) 
Enter 'h' for help.

Answer 1

如果你想Thread::Shared，你需要記住的CPAN是大小寫敏感的，使用sudo cpan install Thread::Shared。你不需要後sudo

Answer 2

我目前使用Perl 5.10.1

做su，它不支持多線程

首先，讓我們確保。如果你有一個支持線程一個Perl，你會得到這樣的輸出：

$ perl -V:usethreads 
usethreads='define'; 

如果這是你得到了什麼，你只是拼寫錯誤「主題::共享」，你甚至不需要安裝變成它已經與Perl。

如果這不是你所得到的，你的Perl不支持線程，你需要創建一個Perl的構建（也就是構建使用-Dusethreads配置的Perl）。您不能只安裝一個模塊來添加線程支持，因爲線程支持需要Perl內部的額外代碼。

爲了使自己的Perl的構建，我建議perlbrew，它安裝如下：

curl -kL http://install.perlbrew.pl | bash 

（你會被指示的東西添加到您的登錄腳本，你應該登錄早在，以確保一切都設置右）

這使得它易於安裝一個新的Perl：

perlbrew install -v 5.16.2 --as=5.16.2t -Dusethreads
