I am building a web app using Node. I started when version 4.0 of Node came out. When I run node -v on my local machine, I see: "v4.0.0". I deployed the site as a Microsoft Azure Web App. However, that introduced a 500 error.
I looked at the logs, and I see the following:
Wed Sep 23 2015 13:29:20 GMT+0000 (Coordinated Universal Time): Unaught exception: SyntaxError: Unexpected reserved word

The line in question uses the class keyword, which is allowed in Node 4.0. That prompted me to check the version of node running in my Azure Web App. From the console in Azure, I ran, node -v again. Now I see, "v0.10.32".
How do I get Node 4.0 running for a Microsoft Azure Web App?
specify the version in your "engines" directive in package.json
{
"engines":{"node":4.0.0}
}

I tried servers nodejs version and always give me this error.
If you paste your regular expression into a regex sandbox, like this one:
https://regex101.com/r/GkwWH2/1
You'll see that it doesn't show any syntax errors.
That would make me suspect that you're running a back-level version of Node JS. And in fact, if you look at your stack trace, you see that you are running Node 8.11.3
at Object.<anonymous> (/home/node/.nvm/versions/node/v8.11.3/lib/node_modules/pm2/node_modules/fas
That regular expression is using features (such as named capture groups) that did not come into Node.js until Node v10.*.
I suggest you update to the latest LTS version of Node, version 14.*: from your stack trace it would appear that you're using NVM, so it should be a simple matter of
sudo nvm install lts/fermium
should do it.
I deployed the same web app to two Azure app services, one the fine, while another is throwing such an error. My web is based on Express, how could I fix this issue? Looks the error is not from my source code.

I came across this issue when I set WEBSITE_NODE_DEFAULT_VERSION to a version that was not compatible with Azure.
It fell back to a really old version of node that does not support arrow functions.
You can verify this by going to the Azure Console and doing node -v
This issue was fixed finally, we raised a ticket to MS, Microsoft redeployed the app service to a new set of servers.Then the web site works.
I'm hosting a NodeJs web app in Microsoft Azure, and I'm receiving the following error:

at the error line:
var Mailgun = require('mailgun-js');
The same application is working properly in another Azure Web App (same config between the two).
To setup the NodeJs version I'm using across all the web apps the WEBSITE_NODE_DEFAULT_VERSION application setting.
I would expect this kind of error with older versions of nodejs, but not with the 8.10.
Any idea?
I just found that the web application with problems was created using a Microsoft template "Node JS Empty Web App".
This template left on the root of the web application the iisnode.yml file that was forcing the version 4.2.4, despite globally was used the 8.10.0.
nodeProcessCommandLine: "D:\Program Files (x86)\nodejs\4.2.4\node.exe"
Removing the iisnode.yml solved the issue.
As mentioned by redeyes.
another approach is to edit the path with the version number
nodeProcessCommandLine: "D:\Program Files (x86)\nodejs\8.10.x\node.exe"
it has been one week now that i was trying to install meanjs stack and had no success.
Everytime I follow some tutorial and get errors. Now I end up with many issues, too much nodejs version, i dont know which one should be with what and why do karma not working ...etc
is there anyway to remove everything and install meanjs correctly and get it running successfully

bower 1.7.9
mongodb v3.0.12
Can anyone please help me, I want to get started.
I haven't dug into it, but I'm guessing the version of node you have doesn't support the 'const' keyword. 0.10.x is a (fairly) old version of node; have you considered upgrading to one of the versions that has ES 6 native support?
I am trying to deploy a node app on Linode (Ubuntu 12.04) while following this guide from Node Knockout: http://blog.nodeknockout.com/post/9300619913/countdown-to-ko-14-deploying-your-node-js-app-to
I have no problems running the server as root, but when trying to start the server as the "deploy" user using sudo start node, I get this error:

I have tried recompiling bcrypt using make clean then make since I thought my module version was incompatible with my version of node (v0.8.18), but that does not seem to be the case since I can start the server as root with no problem. I feel as though the problem lies in how I set up the deploy user, but I am not sure how to proceed.
