After the search said it was NPM config set key error, changed several times http-proxy,proxy found no use, and later with NPM config ls-l see all the config to find is registry "https:// registry.npmjs.org/"is commented out, although do not know when to change, the comments removed and then install the success, so if you encounter this problem can first check whether the registry parameters set, and then check the problem may be solved faster.
