Npm installation error - failed to get local issuer certificate

I get an unable to get local issuer certificateerror unable to get local issuer certificatewhile installing npm:

typings ERR! message Unable to read typings for "es6-shim". You should check the
 entry paths in "es6-shim.d.ts" are up to date
typings ERR! caused by Unable to connect to "https://raw.githubusercontent.com/D

/es6-shim.d.ts"
typings ERR! caused by unable to get local issuer certificate

I recently upgraded node 4 from an earlier version, and it seems that the node becomes more severe when similar problems occur.

There is a problem discussed here that talks about using CA files, but this is a bit above my understanding, and I'm not sure what to do about it.

I am behind the corporate firewall, but I can easily access the URL in the browser.

Does anyone have a further understanding of this problem and what are the possible solutions?

I am wondering about returning to node 0.12 in the meantime :(
