Trouble with contrib-modbus module

jfehl · 7 November 2019 21:09

I am having trouble with contrib-modbus 4.1.3 communicating with a PLC. Version 3.6.1 works fine in a similar setup at a different location. Following the info I try ti install a later version but get the following error even logged in as administrator. Are there any suggestions on loading a previous version, or am I missing something else? v10.16.3 && 6.9.0

C:\Windows\system32>npm install -g node-red-contrib-modbus@3.6.1

Seems like the serialport package is trying to build its native code, but it fails because your build environment isn't properly set up. Python is missing (required for node-gyp to work).

There is a setup guide for Windows on the node-gyp Github page:

Steve-Mcl · 7 November 2019 23:00

The clue is there ^

You actually need windows build tools then try installing that node again

Colin · 8 November 2019 07:18

I don't use Windows, but should you be installing it globally?

kuema · 8 November 2019 08:11

That's a good point, too. You should install nodes locally into your Node-RED workspace (by default .node-red in your user profile).

jfehl · 8 November 2019 14:10

I attempted to install the Build Tools using:

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

at CMD running as administrator. A result was given at the end that Python Installed Successfully, however after trying to run

npm install node-red-contrib-modbus@3.6.1

Did I install the build Tool incorrectly?

kuema · 8 November 2019 15:42

Did you reboot or logout after you installed the build tools? Maybe python isn't in your path yet.

Does it find python if you execute it in cmd shell?

I think there was also an option for your .npmrc to set the path to the python executable by executing:
npm config set python /path/to/executable/python

That's what I did at work on my Windows PC. I can't check it right now as I only have Linux machines at home.

Colin · 8 November 2019 16:29

You are trying to install it from your Windows system folder, you have to do it from your node red folder, or use the node red palette manager in the editor.

jfehl · 8 November 2019 16:46

OK, Python apparently is installed, but maybe not in the correct place?

jfehl · 8 November 2019 16:49

I will try to install from the Node-Red folder now. Thanks

jfehl · 8 November 2019 16:50

Same error, Cant not find Python Executable.

Steve-Mcl · 8 November 2019 17:14

Put path to python27 in your environmental variables.

jfehl · 8 November 2019 17:25

OK, I added Python to the environment variables. I now have a new result, possibly on the right track?

I wish I had more information to offer, but looking at my installation I am using modbus version 4.1.3 and I fear that is I were to go to 5.13.2 I would have the same issue you are. Can you load an older version? I am currently successfully reading my Modbus devices at this version.
