invalid cross-device link when using sls deploy

[jdrylewicz]

Hi, I am able to run your most basic example (packaging the Flask dependency only). When I add more modules in my requirements.txt I am running into issues. I tried everything i could find on forums so far without luck.

Traceback (most recent call last): File "/var/lang/lib/python3.7/shutil.py", line 566, in move os.rename(src, real_dst) OSError: [Errno 18] Invalid cross-device link: '/tmp/pip-target-kj_jmr6f/lib/python/cycler-0.10.0.dist-info' -> '/var/task/cycler-0.10.0.dist-info'

During handling of the above exception, another exception occurred:

I observed the same issue today. I am running the example from https://www.serverless.com/blog/serverless-python-packaging

serverless.yml service: numpy-test

provider: name: aws runtime: python3.8

plugins:

• serverless-python-requirements

custom: pythonRequirements: dockerizePip: non-linux

functions:

hello: handler: handler.hello_

handler:

import numpy as np

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

print("Your numpy array:")
print(a)

if name == "main": main('', '')_

ok, this fixed the issue: https://github.com/UnitedIncome/serverless-python-requirements/issues/556#issuecomment-728226895

And now bumping immediately in another issue.

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined at readFile (fs.js:320:10) at go$readFile (/usr/local/lib/node_modules/serverless/node_modules/graceful-fs/graceful-fs.js:118:14)

ok, this fixed the issue: #556 (comment)

And now bumping immediately in another issue.

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined at readFile (fs.js:320:10) at go$readFile (/usr/local/lib/node_modules/serverless/node_modules/graceful-fs/graceful-fs.js:118:14)

Did you find a way to fix it? I'm getting the same error here :/

Hi, still have this problem, i tried turning off "Use gRPC FUSE for file sharing" but still with the issue. I don't know what to do.

SOLVED: Just make a "sudo npm install --save serverless-python-requirements"
