Error: Cannot find module 'vsts-task-lib/task'

See original GitHub issue

Following the Typescript task documentation, I was able to get a task running locally by calling node index.js

However once I’ve built and published it to my VSTS account, I get the following error when I try to use it in a pipeline:

vsts-task-lib is definitely listed as a dependency in my package.json, and I would expect it to be pulled down for the task. Is there anything I need to do to get the build agent to run an npm install for the task?

It’s working now I’m not sure why … However, I did validate that npm_modules will need to be in the same directory as the index.js file under the task folder.

It might be too late, but mentioning this anyway for people who hit this in the future. I just published a starter template for creating custom pipeline tasks in TypeScript. I spent far too much time in setting this up for myself so I’d be happy if it saves some time for people who hit this going forward.
