NPM self_signed_cert_in_chain

Question

I am having issues getting NPM to install properly. I have tried stepping through the instructions on several of the posts here on stack overflow, specifically from this thread: SELF_SIGNED_CERT_IN_CHAIN error while using npm install

Also I have tried going through the documentation on NPM's site: http://blog.npmjs.org/post/78165272245/more-help-with-selfsignedcertinchain-and-npm

I am still receiving the error everytime I try to install. please advise.

Solution 1

If you're behind the corporate proxy (which uses e.g. Blue Coat), you should use http instead of https for repository addresses, e.g.

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

^{See: Error: SSL Error: SELF_SIGNED_CERT_IN_CHAIN while using npm.}

You can also import failing self-certificate into your system and mark as trusted, or temporary disable SSL validation while installing packages (quick, but not recommended method):

npm config set strict-ssl false

^{See: Error: SSL Error: SELF_SIGNED_CERT_IN_CHAIN while using npm.}

---

The recommended way (and more painful) is just to point to the right certificate file, e.g.

npm config set cafile "<path to your certificate file>"

Solution 2

This works for me:

$ export NODE_TLS_REJECT_UNAUTHORIZED=0
$ npm install

Solution 3

Use this command below and it could work fine:

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