I am running ubuntu and I am trying to control my totem functions via my mobile. I came across this application but I am not sure how to make it work !!
I have nodejs installed and I have already run the npm install command which did not return any errors.
The link below is the github page but unfortunately does not contain my documentation on how to use it.

So, to be clear, I'm not asking about the possibility of INSTALLING multiple versions of Node, or the capability of switching between multiple versions with something like nvm.
(The original nvm package for Mac/Linux has an "exec" command that lets you run a command under a particular version of node. I think this would be a solution--but the nvm for Windows package doesn't have that "exec" command.)
Context:
I have an Azure function app API that must run under Node 14.0.0 (a requirement of Azure Function Core Tools version ~3, which itself is a customer requirement).
I also have a basic React app (using Parcel bundler) that runs under Node 11.14.0. I can't update the Node version to 14.0.0 because of an error ("Cannot locate the bindings file...").
For testing purposes, I need to run both simultaneously, so I can hit my API with my React app.
I have tried starting my API under Node 14.0.0, then using nvm to switch to 11.14.0 to run the React app, but it causes the API to fail with an "unsupported Node version" error. I haven't tried the converse approach because this error (along with the UAC prompt) tells me that the Node version in use is global.
Does anyone have any ideas of how to run two versions of Node on Windows? Or can anyone suggest another practical work-around?
Thanks in advance.
I am using chrome-launcher for running lighthouse programmatically. It works fine locally but when I run it on azure I am getting an error.
On this statement const chrome = await chromeLauncher.launch({chromeFlags: ['--headless']}); I am getting the following error:
ChromeNotInstalledErrorat new LauncherError (C:\home\site\wwwroot\node_modules\chrome-launcher\dist\utils.js:37:22)at new ChromeNotInstalledError (C:\home\site\wwwroot\node_modules\chrome-launcher\dist\utils.js:68:9){message: 'No Chrome installations found.',code: 'ERR_LAUNCHER_NOT_INSTALLED'}
How can I solve this?
You need to install Chrome on the Azure Function app somehow.
One way to do this is by using an npm dependency that installs Chrome as part of its install process. Examples of this are puppeteer and playwright. Although then you end up with some unnecessary dependencies.
You could also have a startup script or something that installs Chrome before running chrome-launcher/lighthouse. You'll need to tell crome-launcher where Chrome is installed if it's not a standard place using chromePath options or CHROME_PATH environment variable link.
You also have to ensure you do a Remote Build for the Function app.
You will also run into this error, which has a possible workaround: https://github.com/GoogleChrome/chrome-launcher/issues/188
Overall it's not easy. I actually ended up moving my workflow to GitHub Actions instead as Chrome is already installed on their runner images.

Just installed the latest Domino 10.0.1 Server on my linux machine and also installed and configured the latest proton package. As far as I can tell it's all running fine.
Next I plan to try my first Node-RED flow using the new Domino10 nodes. So I installed the 'node-red-contrib-dominodb' palette.
Finally tried my first very simple flow trying to query node-demo.nsf as it's described here. From what I read there I assumed that it's sufficient to install the palette, but that obviously is not the case:
as soon as I hit 'Deploy' I receive this error:
Error: Cannot find module '#domino/domino-db'
So I thought that I maybe still have to do a global install in node.js using
npm install -g <package-path>/domino-domino-db-1.1.0.tgz
This indeed created a local #domino/domino-db module inside my node.js npm\node_modules folder. But obviously my node-red environment doesn't know about it.
Question is: how do I register / install that npm package for my local node-red environment?
IBM's instructions (https://flows.nodered.org/node/node-red-contrib-dominodb#Installation)
Say to go view this guide(https://github.com/stefanopog/node-red-contrib-dominodb/blob/master/docs/Using%20the%20new%20Domino%20V10%20NodeRED%20nodes%202.pdf) for installing the domino-db module.
The link is broken, here's an old copy: https://github.com/stefanopog/node-red-contrib-dominodb/blob/a723ef88498c5bfa243abd956a7cc697f0a42610/docs/Using%20the%20new%20Domino%20V10%20NodeRED%20nodes%202.pdf
I believe the section you want is called "Import the tarball". The steps before that require you to unpack and then re-pack the module... which is unnecessary. Just use the tgz that was in the AppDev Pack to begin with.
Today I was trying to work on Angular2 (template https://akveo.github.io). As per installation guide, I ran following commands.
I have installed Node.js v6.9.1.
npm install --Worked fine.
npm server --Failed with below error.
E:\........\node_modules\script-ext-html-webpack-plugin\index.js:3
const INLINE = 'inline';
^^^^^
SyntaxError: Use of const in strict mode.
at exports.runInThisContext (vm.js:73:16)
at Module._compile (module.js:443:25)
After many random searches and failing to resolve it, I decided to think about it with a calm head. To me it looks like it is a problem with ES2015/ES6. Package script-ext-html-webpack-plugin uses const variable which is a ES2016 feature. However system is unable to resolve it.
Also this problem can come with any package like hapi, selinium etc. But everything should have same solution I guess.
I have tried many related commands on the installation guide of the website mentioned above but nothing works and ends with same error. I have also many have faced same issue online but nothing concrete is visible as answer.
Could anyone help me out?
Update
Below approach has also fixed many of my colleague's machine who were facing some random errors with nodejs.
This problem is resolved in at least my machine. I am certainly not a person who understand nodejs completely but got it working after some googling. The solution given below may be common to many other issues I guess.
The system I am working has Windows 10 as Operating System and has 64 bit processor.
Go to control panel and uninstall nodejs (just to make sure you do not have traces of any previous install).
Install latest version of nodejs from their website (I installed v6.9.1 for 64 bit processor).
Go to Environment variables for system (just type environmental variables in start menu if using Windows 10) and edit the Path. Delete ‘C:/Program Files (x86)/nodejs’ (as I had installed 64 bit nodejs). This ensures when using command you do not use any other previously installed nodejs.
Start command prompt in Admin mode and navigate to your project and run npm install.
In case you get any/some error, then run npm info graceful-fs -v or npm info graceful-fs whichever runs in your machine.
Then run npm update -g npm.
Then run npm install again and this time it should work.
Run npm start and everything should work fine.
On running website, sometimes we see any other issue and that can be seen from console logs. But good thing is, console logs also tell you the problem. In most cases its related to 32 bit and 64 bit processor due to our recent changes. In my case, I was facing issue with SASS configuration due to 32/64 bit machine and console log asked me to run npm rebuild node-sass to fix the issue.
Go back to command prompt, hit Ctrl+C to stop npm server. Run node rebuild node-sass. Run npm start again and everything should be working.
Hope it helps.
I am following the guide from phoenix framework to create a simple application under windows 10 local machine. All goes well even after issuing the command mix ecto.create the application is being created but the at the end I am getting an error:

Brunch 2+ requires node.js v4 or higher.....
Tried to upgrade with the command

but failed several times.
I can load and see the page of phoenix server but without css styles.
how can I fix the errors?
Make sure your DB is up and running.
To see the css applied,
npm install --save babel-preset-es2015
