Not able to install npm install -s camunda-external-task-client-js

BPMN & Modeling Discussion & Questions

HI, I am new on the forum and Camunda user as well. I´m trying to run a JavaScript external task in Camunda Run but when I insert the installing code: npm install -s camunda-external-task-client-js on Visual studio or Windows Powershell it doesn´t give me back a node_modules and packagelock.json. What can be the problem?

This is what I got:

  • camunda-external-task-client-js@2.1.0
    updated 1 package and audited 74 packages in 0.814s

Hi @anchor
Welcome to the forum.

Are you running the npm installcommand in the same directory as your worker?

Hi @Niall, thank you for your quick reply. Actually, i´m doing exactly what you made in this video Camunda Platform Tutorial: Building and Running a JavaScript External Task in Camunda Run - YouTube. I checked and the command npm install is in the same directory. Of course when I made the step further of inserting the node. /… it doesn´t work as well. In the latter step the message of error I receive back is:

node. : The term ‘node.’ is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct
and try again.
At line:1 char:1

  • node. \sendLetterWorker.js
  •   + CategoryInfo          : ObjectNotFound: (node.:String) [], CommandNotFoundException
  + FullyQualifiedErrorId : CommandNotFoundException

I don´t know if this can give you more information.

Do you have have node installed?
You’ll need it to run the npm commands. You can download it here: Download | Node.js

It is already installed Node.js. :pensive:

If you’re still getting the error that nodeis not recognized you probably need to add it to your path.
Try following these instructions: node.js - Fixing npm path in Windows 8 and 10 - Stack Overflow

Hi @Niall, I followed your suggestion but nothing happened. It can be related to some problem with the installation of node.js? I tried to uninstall and install one more time node.js but on powershell I got this message:

WARNING: ‘choco’ was found at ‘C:\ProgramData\chocolatey\bin\choco.exe’.
WARNING: An existing Chocolatey installation was detected. Installation will not continue.

Type ENTER to exit:

Is there another wat to implement an external service task to overcome this problem?
