Serverless-python-requirements: EEXIST issue with sls deploy and dockerizePip

[kalote]

Hello,

When I try to "sls deploy" using "dockerizePip: true" option, i get the following error:

Serverless: Invoke deploy
Serverless: Invoke package
Serverless: Invoke aws:common:validate
Serverless: Invoke aws:common:cleanupTempDir
Serverless: Installing required Python packages with python3.6...
Serverless: Docker Image: lambci/lambda:build-python3.6
Serverless: Linking required Python packages...

  Error --------------------------------------------------

  EEXIST: file already exists, symlink '/Users/me/project/test/lambda/.serverless/requirements/requirements.txt' -> './requirements.txt'

     For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

  Stack Trace --------------------------------------------

Error: EEXIST: file already exists, symlink '/Users/me/project/test/lambda/.serverless/requirements/requirements.txt' -> './requirements.txt'
    at Object.fs.symlinkSync (fs.js:1014:18)

I'm running on macOS, with latest sls version, and latest serverless-python-requirements version.

Thanks for your support.

Can you post your serverless config file please?

service: test

provider:
  name: aws
  runtime: python3.6
  region: ap-southeast-1
  environment:
    JENKINS_TOKEN: ${file(./serverless.env.yml):JENKINS_TOKEN, ''}

    memorySize: 128
    events:

          path: /check_access
          method: get
          cors: true

custom:
  pythonRequirements:
    dockerizePip: true

My requirements.txt:

requests

FYI, here is what i did from start:

• tried to run sls deploy without dockerizePip settings => issues because i have python3.7 installed, not 3.6
• tried to run sls deploy with dockerizePip settings => issue about EEXIST
• tried to run sls deploy without dockerizePip settings but with pythonBin settings => same issue (EEXIST)

Serverless: Installing required Python packages with /usr/local/bin/python3.6...
Serverless: Linking required Python packages...

  Error --------------------------------------------------

  EEXIST: file already exists, symlink '/Users/me/project/testlambda/.serverless/requirements/requirements.txt' -> './requirements.txt'

     For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

  Stack Trace --------------------------------------------

Error: EEXIST: file already exists, symlink '/Users/me/project/test/lambda/.serverless/requirements/requirements.txt' -> './requirements.txt'

Hope that helps :)

NOTE: After renaming requirements.txt into requirements, i don't have the issue anymore, BUT, the requirements are not packaged in the resulting zip file...

Could you try rm -rf .serverless and re running (i think the pythonBin route is preferable in your case

[kalote]

Thanks for the support, but I already tried to remove the .serverless
folder and start from fresh, but I've got same result. EEXIST error.

This is very odd. I tested this on macOS 10.13.4 and wasn't able to recreate the issue.

My test repo is https://github.com/dschep-bug-repos/sls-py-req-278

Could you follow the readme and confirm it causes this EEXIST issue for you too?

[kalote]

Using your repo, i don't have the EEXIST issue anymore ... Which is very
odd, as i don't see a lot of differences between your setup and mine.

I will try to investigate a bit more on our differences, and keep you
posted.

Thanks for the support

Hey all. I have had the same issue and after some trial&error I found out that the issue was fixed by upgrading the plugin (in my case it was a 3.x.x -> 4.x.x switch, so I suppose sth changed there). @kalote not sure if it's still an issue for you but anyways, for anybody that finds this thread, try running sls plugin install -n serverless-python-requirements.

[AndrewFarley]

Added a label for visibility, please comment if you or anyone can replicate this with the latest release of the serverless framework and this plugin, otherwise will close.

I'm having a similar issue on 5.1.0.

I'm using poetry and Python 3.7.

i have very little relevant in my serverless file:

package:
  include:
    - "!./**"
    - proj_dir/**
  excludeDevDependencies: false

sls deploy works just fine, but

sls deploy -f myFunc
Serverless: Generating requirements.txt from pyproject.toml...

  Error --------------------------------------------------

  Error: EEXIST: file already exists, link....
