You can also open up the command line and run: Open up the terminal and run the following code (for Unix):įor Windows, edit this environment variable in System Properties. We can set environment variable NODE_TLS_REJECT_UNAUTHORIZED to be zero: Use the command export NODE_TLS_REJECT_UNAUTHORIZED=0 If this does not work, upgrade to the latest version of node.js - since the latest stable version of node includes the NPM client that does not have this issue. This just means to let NPM not use the bundled SSL that was not working. Then additionally, run the following to set ther certificate authority: Run the following to update your NPM client: To fix this issue, we need to update our NPM client. However, NPM clients after Feb 2014 should not use self-signed SSL certificates anymore, so should not have this problem ( ). This was previously necessary because the client used a self-signed SSL certificate. The npm client used a certificate authority (CA) file that was bundled into the client itself.
One of the reason for this to occur is that with old versions of Node and NPM, they used a self signed certificate! Upgrade Node and NPM version or let NPM to use known registrars! Sometimes the cause of this can be using a private NPM package repository, and that repo does not have the right SSL cert. Self signed certificates in the certificate chain are not trusted by the system and therefore gives this error. When we come up with this error, it usually means that we are install a package from NPM that contains a self signed certificate.
