I am trying to install lib MQTT v5 and it is not installing, returns a series of errors and aborts the installation. My Environment is Windows 6, node 11.11.0 and npm 6.10.0. Could someone clarify how I should proceed to be able to perform the installation?

How do you want to use mqtt.js? This error occurs only if you download mqtt.js sources and install all dependencies. But you don't need to download mqttjs sources for developing your own applications that use mqttjs. You should init new node project and simply install mqttjs as a dependency. npm init npm i mqtt if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 Alternatively if you want to continue developing mqttjs library you should clone mqttjs repo git clone https://github.com/mqttjs/MQTT.js.git if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 then you should update zuul-ngrok dependency npm i git+https://git@github.com/rase-/zuul-ngrok.git if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 and then you can install all dependencies of mqttjs npm i if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 I hope this helps you ;)

DaltonLuisBoer can you provide a little more details on the error output?

MQTT.js depends on zuul-ngrok version 4.0.0 and it depends on ngrok 2.1.8 and it does not work on windows. And new version of zuul-ngrok with new version of ngrok which works in windows is not yet on npmjs.com

DaltonLuisBoer

dexif Well, could you tell me if there is another lib for nodejs that supports the V5 MQTT protocol?
Because I specifically need the shared subscription functionality for the client load balance.
Thank you for your attention.

You can try to use yarn instead npm. Maybe this will help you:

How do you want to use mqtt.js?
This error occurs only if you download mqtt.js sources and install all dependencies.
But you don't need to download mqttjs sources for developing your own applications that use mqttjs.
You should init new node project and simply install mqttjs as a dependency.

npm init
npm i mqtt

Alternatively if you want to continue developing mqttjs library you should clone mqttjs repo

git clone https://github.com/mqttjs/MQTT.js.git

then you should update zuul-ngrok dependency

npm i git+https://git@github.com/rase-/zuul-ngrok.git

and then you can install all dependencies of mqttjs

npm i

I hope this helps you ;)

Hello,
Thanks for your help, it is now working in conjunction with broker EMQ X protocol 5, which allows us to use shared subscription, allowing our customers to load balance.
Greetings from Brazil
Thanks again.

DaltonLuisBoer
Glad to hear that! 😀 It is very cool!
Can you describe how you use load balancing in your case and what is your project? ;)
If this is not a secret of course.
