                     Cannot find npm-shrinkwrap.json. Did you forget to put it in target sources? This package will fall back to inject package.json with pants BUILD dependencies including node_remote_module and other node dependencies. However, this is not fully supported.
                     Removing [u'dependencies', u'devDependencies', u'peerDependencies', u'optionalDependencies'] from package.json for server-project
