serverless deploy python code issue

[fshah7]

Hi,

I am trying to deploy my python code on aws lambda using serverless and I am following the below tutorial:
https://serverless.com/blog/serverless-python-packaging/

When I am trying to deploy I get the below error:

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

Exception:
Traceback (most recent call last):
File "/var/lang/lib/python3.6/site-packages/pip/basecommand.py", line 215, in main
status = self.run(options, args)
File "/var/lang/lib/python3.6/site-packages/pip/commands/install.py", line 388, in run
ensure_dir(options.target_dir)
File "/var/lang/lib/python3.6/site-packages/pip/utils/init.py", line 83, in ensure_dir

File "/var/lang/lib/python3.6/os.py", line 220, in makedirs
mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/var/task/.serverless/requirements'

Can anyone help me out with that.

Hmm. interesting. Could you share your serverless.yml and what operating system you're on?

[fshah7]

Sure. I am on mac os.
Here the serverless.yml file.

plugins:
  - serverless-python-requirements

custom:
  pythonRequirements:
    dockerizePip: true1321

service: numpy-test

provider:
  name: aws
  runtime: python3.6

functions:
  numpy:
    handler: handler.main

---

Here is the handler.py

try:
    import unzip_requirements
except ImportError:
    pass

import numpy as np


def main(event, context):
    a = np.arange(15).reshape(3,5)
    print("Array is ",a)

if __name__ == "__main__":
        main('', '')

Hmm. I assume you're using Docker for Mac? Is this project inside your home directory(within /Users)?

[fshah7]

Yes I am using docker for mac. The project is under my home directory

[fshah7]

Just FYI,

I am following this blog: https://serverless.com/blog/serverless-python-packaging/

and facing the issue when I try serverless deploy

I have the same issue on mac. directory is a subdirectory of my home directory.

This is what our serverless looks like. Weirdly, it works for my colleagues who're on mac os as well, just not for me.

plugins:
  - serverless-python-requirements

custom:
  pythonRequirements:
    dockerizePip: true
(...)

[dschep]

How do you & your colleagues have docker installed? My mac using colleagues use Docker for Mac and it works for them. Are you maybe using an older docker on mac technique such as docker-machine or boot2docker?

[pr130]

Thanks for the fast reply. I have Docker for Mac and I think my colleagues have that as well.
I have had some issues with docker itself (long startup, some hangups (needed to restart)) but it's up and running now.

Some other info: I installed the plugin like it is described on the serverless website, not how you guys wrote in the readme. is that relevant?

I also ran the command with debug on and this is the stack trace just in case there's something totally obvious. Tbh, i think it's something with my setup and permissions to my user, so i'll do some more digging into that tomorrow and post what i've found here as at least someone had the same problem.

That installation technique is fine, the sls plugin install command is a newer addition to serverless. Alas nothing jumps at at me in that trace back ☹️

[memarsh]

@friep Did you ever find a solution for this problem?

[pr130]

@memarsh no unfortunately not.. i was able to use dockerizePip=false for a while but now I'd really need to use =true because we need to compile stuff. So I'm back to this problem.
