After trying out every solution I could find:

Turning off strict ssl: npm config set strict-ssl=false
Changing the registry to http instead of https: npm config set registry http://registry.npmjs.org/
Changing my cafile setting: npm config set cafile /path/to/your/cert.pem
Stop rejecting unknown CAs: set NODE_TLS_REJECT_UNAUTHORIZED=0

The solution that seems to be working the best for me now is to use the NODE_EXTRA_CA_CERTS environment variable which extends the existing CAs rather than replacing them with the cafile option in your .npmrc file. You can set it by entering this in your terminal: NODE_EXTRA_CA_CERTS=path/to/your/cert.pem

Of course, setting this variable every time can be annoying, so I added it to my bash profile so that it will be set every time I open terminal. If you don’t already have a ~/.bash_profile file, create one. Then at the end of that file add export NODE_EXTRA_CA_CERTS=path/to/your/cert.pem. Then, remove the cafile setting in your .npmrc.

A quick solution from the internet search was npm config set strict-ssl false  luckily it worked  But as a part of my work environment  I am restricted to set the strict-ssl flag to false    Later I found a safe and working solution   npm config set registry http   registry npmjs org      this worked perfectly and I got a success message Happy Hacking  by not setting the strict-ssl flag to false

Had the same error   Looks like it is related to SSL certificates   If you are using NPM for public packages  don t need the security of HTTPS  you can turn off strict SSL key validation with the following command   This might be the simplest fix if you re just looking to install a few publicly available packages one time   npm config set strict-ssl false

Changing the NPM repo URL to HTTP works as a quick-fix  but I wanted to use HTTPS   In my case  the proxy at my employer  ZScaler  was causing issues  as it acts as a MITM  causing certification verification issues   I forgot I found a script that helps with this and Git  for cloning GitHub repos via HTTPS had the same issue  and forked it for my use  Basically  it does the following for git   git config --global http proxy http   gateway zscaler net 80  git config --system http proxy http   gateway zscaler net 80    and for Node  it adds proxy http   gateway zscaler net 80  to the end of c  Users  USERNAME npm  npmrc  That solved the issue for me

what may be happening is your company decrypts certain traffic and re-encrypts it with their certificate  which you probably already have in your keychain or trusted root certificates   if you re using node 7 or later I ve found this fix to be compatible with node and node-gyp  for Windows you ll need to do this differently  but you basically just need to add this environment variable    export NODE EXTRA CA CERTS  absolute path to your certificates pem   in Windows you may need to remove the quotes - see comments   the pem file can have multiple certificates  https   nodejs org api cli html cli node extra ca certs file  make sure your certificates are in proper pem format  you need real line breaks not literal  n   I couldn t seem to get it to work with relative paths    or     This fix basically tells npm and node-gyp to use the check against the regular CAs  but also allow this certificate when it comes across it  Ideally you would be able to use your system s trusted certificates  but unfortunately this is not the case
