为什么在通过无服务器部署时,docker不能找到我自己的包？

Question

我想将我的python包部署到亚马逊并通过lambda使其可用.为此,我正在尝试无服务器.

当我尝试部署我的包时,我收到以下错误消息:

我的serverless.yml文件如下所示:

# Welcome to Serverless!
#
# This file is the main config file for your service.
# It's very minimal at this point and uses default values.
# You can always add more config options for more control.
# We've included some commented out config examples here.
# Just uncomment any of them to get that config option.
#
# For full config options, check the docs:
#    docs.serverless.com
#
# Happy Coding!

service: tagdoc # NOTE: update this with your service name

# You can pin your service to only deploy with a specific Serverless version
# Check out our docs for more details
# frameworkVersion: "=X.X.X"

provider:
  name: aws
  runtime: python3.6
  region: eu-central-1
# you can overwrite defaults here
#  stage: dev

plugins:
  - serverless-python-requirements

# You need to have Docker installed to be able to set dockerizePip:
# true or dockerizePip: non-linux. Alternatively, you can set
# dockerizePip: false, and it will not use Docker packaging. But,
# Docker packaging is essential if you need to build native packages
# that are part of your dependencies like Psycopg2, NumPy, Pandas, etc
custom:
  pythonRequirements:
    dockerizePip: true

# you can define service wide environment variables here
#  environment:
#    variable1: value1

# you can add packaging information here
package:
  include:
    - ./nltk_data/*

functions:
  ttxt:
    handler: handler.ttxt
    events:
      - http:
          path: /ttxt
          method: get
          integration: lambda
          request:
            template:
              application/json: '{ "txt" : "$input.params(''txt'')" }'
          response:
            headers:
  turl:
    handler: handler.turl
    events:
      - http:
          path: /turl
          method: get
          integration: lambda
          request:
            template:
              application/json: '{ "url" : "$input.params(''url'')" }'
          response:
            headers:
              Content-Type: "'application/json'"

目录中包含所有必需的文件,特别是内置的python包:

tree -L 2 lambda/
lambda/
??? tagdoc
    ??? pkgg-0.1.0.tar.gz
    ??? handler.py
    ??? nltk_data
    ??? node_modules
    ??? package.json
    ??? package-lock.json
    ??? README.md
    ??? requirements.txt
    ??? serverless.yml
    ??? srv

4 directories, 8 files

我目前正在运行Debian 9.5.我还与一位通过Github运行相同操作系统的朋友分享了代码,似乎他可以部署该软件包.因此,它看起来与我的无服务器/ docker的本地设置有关.但我无法弄清楚如何解决这个问题.任何帮助将非常感激.

requirements.txt只包含一行:

cat requirements.txt 
pkgg-0.1.0.tar.gz

现在包本身有一些依赖性.通过仅包含包,它setup.py从包中获取文件中的依赖项.

编辑

正如其中一条评论中所述.这是我的.gitignore

#Compiled source#
#################
*.pyc

# no data files #
################
*.csv

#Log files#
#################
*.log

#swap files#

stunnel

# Elastic Beanstalk Files
.elasticbeanstalk/*
!.elasticbeanstalk/*.cfg.yml
!.elasticbeanstalk/*.global.yml

#Serverless package
.serverless

这就是我的.serverless的样子.所有的requirements.txt都与上面的内容完全相同.

tree -L 3 .serverless/
.serverless/
??? cloudformation-template-create-stack.json
??? requirements
?   ??? requirements.txt
??? requirements.txt

1 directory, 3 files

问题似乎在里面serverless-python-requirements。就像在4.1.1版本中看起来一样，它可以完美地工作，而在4.2.5中则不能。我在github上提出了一个问题
