Azure Website: Kudu fails to install

2
votes

I started to run into this problem yesterday. Deploys fail when I run:

npm install kudusync -g

with the following error:

Error: SSL Error: CERT_UNTRUSTED

From some searches it appears that one of Kudu's dependencies is self-signed or unsigned. It seems like I can disable SSL checks for Node -- but that seems like a dangerous option and not recommended. Is anyone aware of any other workarounds?

The output in azure is as follows:

remote: npm http GET https://registry.npmjs.org/kudusync[K remote: ......[K

remote: npm http GET https://registry.npmjs.org/kudusync[K remote: .......................................................[K

remote: npm http GET https://registry.npmjs.org/kudusync[K remote: npm ERR! Error: SSL Error: CERT_UNTRUSTED[K

remote: npm ERR! at ClientRequest. (d:\Program Files (x86)\nodejs\node_modules\npm\node_modules\request\main.js:440:26)[K remote: An error has occurred during web site deployment.[K

You're probably using a really old version of NPM. From blog.npmjs.org/post/71267056460 - If you are still using Node v0.6 for some reason, or a very old version of v0.8, you can work around this by doing npm config set strict-ssl false, though I’d really recommend that you upgrade, for this and many other reasons – Pranav
I don't seem to be able to specify a newer version via package.json, but it seems strange that this problem would start suddenly. I had no problem deploying before and have not made any changes to how I deploy. – Alex Schearer

The break most likely refers to this change npm made.

Do you have a custom deployment script, or the standard script? With custom, your options are:

  • use a newer version of npm
  • run npm config set strict-ssl false before running npm
  • if your custom script has a reference to KUDU_SYNC_COMMAND, rename that to KUDU_SYNC_CMD
