receiving error: 'Error: SSL Error: SELF_SIGNED_CERT_IN_CHAIN' while using npm

[问题]

 am using npm v1.0.104/node 0.6.12 on ubuntu - I am receiving the error copied below while attempting to install any new modules via npm (I tested socket.io earlier using http, not https though & am wondering if that could have resulted in the issue with npm/unsigned certs). The error pops up once npm tries to resolve the 'https://registry.npmjs.org' URL. Is there anyway I can ignore the error or perhaps locate/add the cert to a trusted store in order to continue using npm.

Any insight on what needs to be done to resolve the issue will be appreciated (I would prefer to resolve the issue through configuration as opposed to re-installing if possible).

Running the following helped resolve the issue:

npm config set strict-ssl false

I cannot comment on whether it will cause any other issues at this point in time. Hope it helps.

• run "npm config set ca null" instead, ignoring ssl errors is a bad idea – alex Jan 4 '14 at 0:50 
• This is filthily wrong. Why are you even bothering using SSL if every time it does the one thing it's supposed to do you turn it off? "Any time ignoring an error leads to success, developers are going to do just that." – djechlin Jan 13 '14 at 15:53
• Please don't ignore ssl issues, as the error is there for a very good reason. Also, a bit of searching resulted in the following tweet, which links to the official solution to your problem (update npm): twitter.com/npmjs/status/439279809307242496 – Thomas Vervest Feb 28 '14 at 10:11
• This answer shouldn't be the accepted one. – Guillaume Flandre Feb 28 '14 at 13:20
• My issue was caused by a proxy that I'm behind, "npm config set ca null" and 'npm config set ca ""' still gave me the same error, but removing SSL worked perfectly. Sometimes good practice isn't as important as what actually works. – Cory Schulz Aug 27 '14 at 19:02

   

  [注] 我调查了一下,发现node.js的request对象也有strictSSL选项. 只要在调用的时候传入strictSSL: false,问题就解决了. 不用在npm config里面做配置.
