NPM not installing package. Hostname/IP address doesn't match certificate's altnames:

Question

For a solution, see below

It was working yesterday, but I don\'t know what happened to it.

NPM is not installing the package. The hostname/IP addr

Answer 1

Add the following line to the /etc/hosts file:

104.16.16.35 registry.npmjs.org

Answer 2

Try to change the default registry:

npm config set registry http://registry.npmjs.org

For everyone who is stuck with mup deploy:

docker: { // change to 'abernix/meteord:base' if your app is using Meteor 1.4 - 1.5 image: 'abernix/meteord:node-8.4.0-base', buildInstructions: [ 'RUN npm config set strict-ssl false' ] },

Answer 3

npmjs has a DNS problem according to its incident report: DNS misconfiguration cached in ISP DNS caches.

To solve your problem, do this:

1. dig www.npmjs.com @1.1.1.1

   Sample output on Linux

   ; <<>> DiG 9.10.3-P4-Ubuntu <<>> www.npmjs.com @1.1.1.1
   ;; global options: +cmd
   ;; Got answer:

   2. Get resolved IP address: 104.16.109.30 in my case

   3. Add new entry in your /etc/hosts file

      echo "104.16.110.30 www.npmjs.com registry.npmjs.org" >> /etc/hosts
