Hi,

I used in the past node-red-contrib-zwave, but today I crashed my node red _(I have no idea why, but it did, something with a modbus flow that probably caused a loop or so....)_

Only option was to delete my flows and even after that I updated to the latest version of node-red.  
After back importing my project, only the node-red-contrib-zwave was not happy because of the node js version...

I can't really explain what I did, but I've uninstalled node-red-contrib-zwave from the pallet, update my whole PI, and now, when I want to re-install node-red-contrib-zwave it's not possible.

I get following message

```auto

```

I now I should install some prerequisites, but there I also have no succes.

So, as totally not a Linux man, can someone help me step by step to get this node back installed on my system, so my zwave part of the home works back again.

Thanks

I think there are parts that are no longer working with that node.

I would recommend to use [node-red-contrib-zwavejs](https://flows.nodered.org/node/node-red-contrib-zwave-js) instead, yes you will need to rework the flows, but this node works without any issues (unlike the various zwave nodes)

It is actively maintained and has quite some cool features (including a topology map of all devices/coordinators).

No, it probably wasn't the only (or best) option. For the future, if you start node-red using  
`node-red --safe`  
it will start the editor without starting the flows, then you can sort out the problem and deploy, at which time it will start the flows.

I have no problems installing a different node and rework my flows, but the one you are suggesiting is causing the same problem +/-

So, it seems that my python version is not up to date or what should I understand out of these logs.

Does it succeed if you go into your .node-red folder and run  
`npm install node-red-contrib-zwave-js`  
If that gives the same error (exactly the same) then what does this give  
`which python`  
and assuming that gives you the location of python (say, for example /path/to/python) what about  
`ls -l /path/to/python`

**[Edit]** Also what OS and version are you running?

Hi Colin,

1. run the install **IN** the folder gives +/- the same error.  
He is not happy about Phyton.. here he does talk about different version. And that's the part I don't understand about Linux, it seems you can install things on multiple levels and I don't see how that structure works.

1. 2nd Question is indeed the location.. (I've also run this in the node-red folder)

```auto
pi@raspberrypi:~/.node-red $ which python
/usr/bin/python

```

1. And there we have indeed the older version of 2017...  
Next question will be how we need to update this... (and I also installed yesterdag the newest version... so I don't follow this part)

```auto
 pi@raspberrypi:~/.node-red $ ls -l /usr/bin/python
lrwxrwxrwx 1 root root 9 jan 24 2017 /usr/bin/python -> python2.7

```

1. I'm running on this OS

```auto
pi@raspberrypi:~/.node-red $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"

Hello @NickB ,

Being the author of **node-red-contrib-zwave-js** , thought I'd chip in.

Please see [These requirements](https://github.com/zwave-js/node-red-contrib-zwave-js/wiki/getting-started#before-you-begin).

Python 3.6 I think should suffice.  
The serialport package depends on it for building a Native NodeJS Module (if a prebuilt binary is not available)

Try this.

```auto
sudo apt update
sudo apt full-upgrade
sudo apt install python3

```

EDIT:  
Seems like that won't cut it.  
_if_ you do transition to zwave-js, you can compile python 3.6 as follows:

Source: [Installing Python 3.6 on Raspbian · GitHub](https://gist.github.com/dschep/24aa61672a2092246eaca2824400d37f)

**Prerequisite installs:**

```auto
sudo apt-get update
sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

```

**Grab Source, Compile, Install**

```auto
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
tar xf Python-3.6.5.tar.xz
cd Python-3.6.5
./configure
make
sudo make altinstall

```

Proceed to install **node-red-contrib-zwave-js**

The problem is that the node says it needs at least Python 3.6.0 but it seems that version is not available for Stretch. If you google for how to install 3.6 on a pi you will find suggestions. Alternatively I guess that an upgrade to buster would do it, though can't check that now.

Ok, I'm back in the game, everything works back.

FYI:

`sudo apt install python3`

Here he indeed said another time the latest version was already installed.

Then I just run all the other command of @ [marcus-j-davies](https://discourse.nodered.org/u/marcus-j-davies) (in the .node-red folder, don't know if that's important) and after that I was able to fullfil the setup.

Thanks to you all for helping me out.

Nice!

_if_ you did transition to zwave-js hit me up here, or contact us on Github - whatever your poison.
