V4: Unrecognized command “plugin install” v4.0.26

[ryan-bloom]

Issue description

Hi! I was using serverless framework v3.38.0 to build a python lambda in aws and it was working as expected with my requirements.txt file to import some dependencies into my lambda function. With serverless v3.38.0 I was able to simply run the command sls plugin install -n serverless-python-requirements as explained here.

However with the upgrade to serverless v4.0.26, I’m unable to run this command as I get the following error:

After that errored, I manually added this plugin to my serverless.yml file and manually installed it with npm install serverless-python-requirements --save-dev, but when deploying my lambda and triggering it, I still get failures saying that my imported packages from requirements.txt can’t be found.

Any thoughts? Is this a known bug in v4 that is going to be addressed? Thanks!

Context

I downgraded my serverless version to previous 3.38.0 to get this to work for me so my support --summary does not reflect the error case that I saw:

Environment: darwin, node 22.1.0, framework 3.38.0 (local) 3.38.0v (global), plugin 7.2.3, SDK 4.5.1 Credentials: Serverless Framework Provider: "default" (https://app.serverless.com/ebbcarbonrb/apps/ebb-event-to-timestream-lambda/ebb-event-to-timestream-lambda/dev/us-west-2/providers) Docs: docs.serverless.com Support: forum.serverless.com Bugs: github.com/serverless/serverless/issues

Thanks for reporting @ryan-bloom. We haven't heard this yet, but we'll look into this right away, regardless.

@ryan-bloom Unfortunately I was not able to reproduce this. We did have an issue with plugin install recently, but that was fixed. Could you please make sure you are running the latest version of 4.0.33 and try again? 😊

I'm not sure that serverless-python-requirements is marked compatible with serverless@4 just yet:

https://github.com/serverless/serverless-python-requirements/blob/6e806c09686e57af93904af1d46b3b20aa62a202/package.json#L81 shows

  "peerDependencies": {
    "serverless": "^2.32 || 3"
  },

We came across this thread from renovatebot trying to upgrade from serverless v3. Trying to install using our new package.json

{
  "devDependencies": {
    "serverless": "^4.0.0",
    "serverless-python-requirements": "^6.1.0"
  }
}

prints

@darthwalsh Just updated that package.json to work with version 4

[ryan-bloom]

Upgraded to serverless 4.0.33 and running the plugin install command gets the same error that @darthwalsh saw:

@ryan-bloom the issue is in "serverless-python-requirements": "6.1.0" -- we need to wait for a new release in https://github.com/serverless/serverless-python-requirements/releases
