cpan>h
获得帮助
cpan>m
列出CPAN上所有模块的列表
CPAN> d /bioperl/
查询有关bioperl的模块
CPAN> install modulename
安装指定的模块
CPAN>o conf init
如要重新配置CPAN,可先进入CPAN,然后在CPAN命令行(即CPAN>)键入以下指令:
退出
cpan>q
*****
cpan的配置文件: /usr/lib/perl5/5.8.8/CPAN/Config.pm
可以更改urlist改变镜像站点.
如果需要重新配置CPAN,输入:
#cpan
进入cpan后,输入:
#CPAN>o conf init
重新配置后Config.pm如下:
$CPAN::Config = {

安装perl组件出错:
/usr/bin/make — NOT OK
Running make test
Can’t test without successful make
Running make install
make had returned bad status, install seems impossible
一.可以尝试
#cpan
cpan>o conf make /usr/bin/make
cpan>o conf commit
cpan>exit
然后用perl命令再安装一下该组件,看能否成功。
二.原因也可能是默认缓存/root/.cpan中的数据损坏rm -rf ~/.cpan删除后在perl -MCPAN -e shell中执行reload index然后执行install Bundle::CPAN最后执行reload CPAN即可正常通过命令行install MODULES
