cpanm使用

总是忘记模块地址，还是记下为好。
1. 安装cpanm
cpanm其实是一个可执行文件而已。将它下载到bin目录，然后添加执行权限就可以了。
# wget -O /usr/bin/cpanm; chmod +x /usr/bin/cpanm

2. 使用cpanm安装模块
# cpanm -h
  -v,--verbose              Turns on chatty output
  -q,--quiet                Turns off the most output
  --interactive             开启交互配置(required for Task:: modules)
  -f,--force                强制安装
  -n,--notest               Do not run unit tests
  --test-only               只测试不安装
  -S,--sudo                 sudo to run install commands
  --installdeps             只安装依赖模块
  --showdeps                只显示依赖信息
  --reinstall               重新安装
  --mirror                  指定镜像url (e.g. )
  --mirror-only             只从镜像下载
  --prompt                  Prompt when configure/build/test fails
  -l,--local-lib            Specify the install base to install modules
  -L,--local-lib-contained  Specify the install base to install all non-core modules
  --self-contained          Install all non-core modules, even if they're already installed.
  --auto-cleanup            Number of days that cpanm's work directories expire in. Defaults to 7
 
  Examples:
  cpanm Test::More                                          # install Test::More
  cpanm MIYAGAWA/Plack-0.99_05.tar.gz                       # full distribution path
  cpanm # install from URL
  cpanm ~/dists/MyCompany-Enterprise-1.00.tar.gz            # install from a local file
  cpanm --interactive Task::Kensho                          # Configure interactively
  cpanm .                                                   # install from local directory
  cpanm --installdeps .                                     # install all the deps for the current directory
  cpanm -L extlib Plack                                     # install Plack and all non-core deps into extlib
  cpanm --mirror DBI           # use the fast-syncing mirror

参数名直接为模块名称
如，安装MongoDB模块
# cpanm MongoDB
--> Working on MongoDB
Fetching ... OK
Configuring MongoDB-0.702.0 ... OK
==> Found dependencies: DateTime, Tie::IxHash, Data::Types, DateTime::Tiny, Class::Method::Modifiers, boolean, Moose, File::Slurp, Try::Tiny, Test::Exception, ExtUtils::MakeMaker, Test::Warn, File::Temp, JSON
--> Working on DateTime
......  //自动解决依赖模块

为了加快下载速度, 可以指定使用镜像,并只从镜像下载:

3. 删除模块
安装App::pmuninstall模块：
# cpanm App::pmuninstall

删除模块：
# pm-uninstall MongoDB


4. 实际使用#######
wget -O /usr/bin/cpanm --no-check-certificate; chmod +x /usr/bin/cpanm
镜像安装
cpanm --mirror --mirror-only MongoDB
