Sh: 1: serverless: Permission denied

#1

We use Circle CI to package and deploy our serverless API to AWS and have noticed an increasing number of builds with the following error. Has anyone experienced this error and how were you able to resolve it?

#!/bin/bash -eo pipefail
npm run package -- --stage $STAGE --branch $CIRCLE_BRANCH

> example-api@1.0.0 package /home/circleci/project
> serverless package "--stage" "tst" "--branch" "example-branch"

What does it say in here?

We too have been experiencing this recently. We use Circle CI to deploy to AWS via the Serverless framework and we have been finding that a significant number (~15-25%) of deployment workflows fail with this specific error. Re-running the job with no changes usually fixes the issue, which makes this seem like a Circle CI reliability issue.

@brannondorsey: can you supply in this thread the logs that I asked Triqi for? I’m just a fellow CircleCI user, but whoever looks at it will need a reproducible case.

Can you push a minimal example to GitHub?

Hey there @halfer, thanks for your response. I’ve pasted the npm log from a failed deploy today below.

The only thing that I can think of that is notable in our workflow is that we npm install dependencies (including serverless) in one job and then save these dependencies to a workspace that gets mounted to another job container later in the workflow during the deployment. Perhaps there is some sort of race condition where the serverless binary sometimes doesn’t have the correct executable permissions once mounted in the deploy job?

From some research, it looks like you might have mixed sudo and npm - there seems to be some suggestions in this thread not to do that.

Either way, would you provide your config.yml?

Also, I wonder if you could judiciously apply some ls -l to see the user/group/perms of the binary this error might apply to? It looks to me (bearing in mind I don’t do Node) that there is a binary called “serverless” and it is being run by (or in) the “sh” shell. Would this be in a node_modules folder somewhere?

Anyone ever get to the bottom of this? Intermittently seeing this
