This is the default mode. - I(name) must be either a module name or a distribution file. - > If the perl module given by I(name) is installed (at the exact I(version) when specified), then nothing happens. Otherwise, it will be installed using the C(cpanm) executable. - I(name) cannot be an URL, or a git URL. - C(cpanm) version specifiers do not work in this mode. - "C(new) mode:" - "When using C(new) mode, the module will behave differently" - > The I(name) parameter may refer to a module name, a distribution file, a HTTP URL or a git repository URL as described in C(cpanminus) documentation. - C(cpanm) version specifiers are recognized. author: -
