You should be in your .node-red folder if you need to install a node manually using npm. However it is usually much easier to do it from the Manage Palette option in the menu in the node-red editor.
Hi Colin,
Thank you for fast reply. To install the node from Manage Pallete option it was my first try, but it dosn't work. Thats why I try to install manually. now I have the Problem, that Node is displayed in Pallette as installed but not activateted and it's impossible to activate the Node or to uninstall.
Did it install ok when you did it from your .node-red folder?
Have you restarted node-red and refreshed the browser page?
Stop node-red and restart it in a terminal and post the output here, that may give us useful information. When pasting it here (copy/paste please, not screenshot) use the </> button at the top of the forum text entry window and paste it in.
Having said that I am not sure the node does what you think it might do. It appears to consist of only a config node so you can't actually place it on a flow.
the installation seems to be okay with the same warnings..
Node Red is starting now in terminal, in following you will find output till now
root@iot2000:/usr/lib/node/node-red# node red

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials

It will not help that you are running an ancient version of node-red, an obsolete version of nodejs and you are running as root, which is not recommended. If you are running a Debian based Linux then you can update using the script at Running on Raspberry Pi : Node-RED, which works for Debian, Ubuntu and Raspbian.
I should have said, if you want to remove it, but can't from Manage Palette then you can do it from the command line, again from your .node-red folder npm remove node-red-contrib-mpi-s7
then restart node-red and refresh the browser page.
Okay for your Information, I work on the iot2040 from Siemens and I am beginner in this field. It's possible to use the script on iot2040 to for updating node-red and nodjs?
No, but if you search the forum for that device then I think there have been others attempting to get round the problem that it comes with obsolete s/w. I don't remember how successful they were.
Sorry for the late reply, and thanks Colin for calling out!
The node you actually want is node-red-contrib-s7 for communicating with Siemens S7 PLCs. You'll then be able to communicate through MPI with node-red-contrib-mpi-s7 from there then. But be warned that there are lots of system requirements in order to be able to use it (including current versions of Node-RED and Node.JS, as pointed out). That's actually one of the reasons why this has been split from the main node-red-contrib-s7 in the first place.
Hi gfcittolin,
thx for reply, I still have problems to upgrade my node-red and node.js on my iot2040. I get error messages if I start "npm install -g node" hereinafter you will find logfile of installation:
0 warn npm npm does not support Node.js v8.16.0
1 warn npm You should probably upgrade to a newer version of node as we
2 warn npm can't make any promises that npm will work with this version.
3 warn npm You can find the latest version at https://nodejs.org/
