Hi i´m trying out if tradfri in connection with node red is a good option for my home.  
I´ve got the tradfri gateway and some bulbs. For testing purposes I installed node red on my local windows PC.  
Unfortunately i don´t get the connection to the gateway. Presumably it´s becaus of the coap library. They are onloy precompiled for debai raspian and osx. (in C:\Users\User1.node-red\node\_modules\node-tradfri-argon\lib).  
Is there a way the get this working on windows or do i need a raspian?

Looks like the install of this dependency failed. I just tried installing that manually on my W10 dev PC and it worked fine. Do you have build-essentials installed? As with many Node.JS modules, there is a binary component in that module that has to be compiled.

Then I did a `npm install node-red-contrib-node-tradfri` and that worked fine as well.

is build essential a installation in node red (manage palette) or somewhere else? Sorry - I´m new to node red and couldn´t find this through a search.  
I also tried node-ahead-crypto - there is no match in palette

Please read the docs on Node-RED install on Windows

[https://nodered.org/docs/platforms/windows](https://nodered.org/docs/platforms/windows)

node-ahead-crypto is a package used by the node you are trying to install with a successful install it is installed for you.

Hi  
thank yue very much for your support.

As far I understood I´ve forgotten the windows build tools.  
I have installed them with the following commands (admin cmd)

```auto
npm install --global --production windows-build-tools

```

and

```auto
npm install --global --production --add-python-to-path windows-build-tools

```

i also restartet the system.  
But the error while installing the other tradfri module occurs again. Here the output of the command line

Not sure where that comes from but it doesn't look right. It should be:

```auto
C:\Users\Michael\.windows-build-tools\python27\python.exe

```

Note the additional backslash. Can you check your PATH environment variable., it should contain:

```
C:\Users\Michael\.windows-build-tools\python27\

```

and you should be able to run this from the command line:

```
> python --version

```

You should get

```
Python 2.7.14

```

back.

This will happen automatically, you need to get the build stuff sorted or you will have all sorts of issues. This isn't a problem with a Node.JS module or Node-RED, it is an issue with your environment.
