Installs a module and all its dependencies in a resolver. <span class="since">since 1.3</span> The module to install should be available in a resolver, and will be installed in another resolver which should support publish. This is particularly useful for users who only have a private repository, and want to benefit from public repositories from time to time. In this case, when a module is missing in the private repository, a call to install let download the module from a public repository not usually used for dependency resolution, and install it and its dependencies in the private repository.
