aws codeartifact login --tool npm fails with "This command does not support workspaces."

[jfly]

Describe the bug

I cannot run aws codeartifact login --tool npm when inside of a npm workspace. The command fails with "This command does not support workspaces". See the "Reproduction Steps" below for more details.

Expected Behavior

I expect to be able to run this command anywhere and have it behave the same (that is, update my ~/.npmrc file).

Current Behavior

See the "Reproduction Steps" below for an example of how to repro with the errors inline.

Reproduction Steps

To reproduce, create a simple npm workspace and cd into it. I've created a dead simple repo for this:

$ git clone https://github.com/jfly/simple-npm-workspace.git
$ cd simple-npm-workspace/workspace-a

And here's a (redacted) aws codeartifact login command that fails:

$ aws codeartifact login --domain ... --repository ... --domain-owner ... --region ... --tool npm --namespace=...
Command '['npm', 'config', 'set', '...:registry', '...']' returned non-zero exit status 1. Stderr from command:
npm ERR! code ENOWORKSPACES
npm ERR! This command does not support workspaces.

npm ERR! A complete log of this run can be found in: /home/jeremy/.npm/_logs/2024-02-29T19_52_57_750Z-debug-0.log

Or, here's a simpler command that is not redacted:

$ npm config set @foo:registry https://example.com
npm ERR! code ENOWORKSPACES
npm ERR! This command does not support workspaces.

npm ERR! A complete log of this run can be found in: /home/jeremy/.npm/_logs/2024-02-29T19_54_42_376Z-debug-0.log

Possible Solution

This is arguably a bug with npm itself, and it's already filed upstream in npm/cli#6099. I can't tell if they're interested in fixing this, though. There is a workaround described here, which would be easy to port to the relevant calls to npm config set in aws-cli.

I'd be happy to send in a PR implementing this workaround if you're open to it.

Additional Information/Context

I can replicate this issue with aws-cli/2.13.28, npm/10.2.2. This isn't surfaced as a potential issue on https://aws.amazon.com/blogs/devops/publishing-private-npm-packages-aws-codeartifact/ which seems like a miss.

Thanks for reporting this issue and your patience here. I will go ahead and reach out to the CodeArtifact team about the issue as they maintain this customization.
