Freebsd11上安裝PERL模組 freebsd11+ perl module @新精讚

自動目錄

使用pkg安裝
- 列出包含關鍵字的可用模組
- 安裝
使用CPANM
- 安裝 cpanm
- 安裝模組
注意！用pkg有時會刪除一些衝突的套件

使用PERL時最煩人的就是遇到沒有安裝的模組，例如：

Can't locate DBD/mysql.pm in @INC (you may need to install the DBD::mysql module) (@INC contains: /…) at xxx.pl line xx.

在freebsd 11上要安裝pel module，有幾種方式，如cpan, cpanm。

使用pkg安裝

最方便的還是用pkg來裝

列出包含關鍵字的可用模組

例如要列出有關鍵字DBD的模組，使用pkg search DBD

# pkg search DBD
p5-AnyEvent-DBD-Pg-0.03_2      Perl extension for AnyEvent interface to DBD::Pg async interface
p5-DBD-AnyData-0.110_1         DBI access to XML, CSV, and other formats

這裡會列出很多，你只需要安裝你需要的模組即可

安裝

# pkg install p5-DBD-mysql-4.050

這樣就可以了

使用CPANM

安裝 cpanm

# pkg search cpanm

p5-App-cpanminus-1.7042 Perl extension to get, unpack, build, and install modules from CPAN
p5-App-cpanminus-reporter-0.17 Perl extension to send cpanm output to CPAN Testers database

# pkg install p5-App-cpanminus-1.7042

安裝模組

# cpanm DBD::MariaDB

注意！用pkg有時會刪除一些衝突的套件

pkg雖然方便，但使用pkg安裝時有時會因為套件不相容，他會列出要刪除的套件，請不要都不看一直按Y，

然後刪了套件都不知道，因為我就幹過這種事，然後才發現套件被我自己刪了。

一開始我還懷疑被同事刪掉什麼的，原來是我自己白痴啊

例如

# pkg install p5-DBD-mysql
Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
Checking integrity... done (1 conflicting)
- mysql56-client-5.6.44 conflicts with mariadb103-client-10.3.13_1 on /usr/local/bin/msql2mysql
Checking integrity... done (0 conflicting)
The following 4 package(s) will be affected (of 0 checked):

Installed packages to be REMOVED: <== 提示你會刪除套件
mariadb103-client-10.3.13_1
mariadb103-server-10.3.13 <== 把你的server刪掉

New packages to be INSTALLED:
p5-DBD-mysql: 4.050
mysql56-client: 5.6.44 <== 但是只裝client不裝server

Number of packages to be removed: 2
Number of packages to be installed: 2

The operation will free 200 MiB.

Proceed with this action? [y/N]: n <== 上面要看清楚才按 y
