如何在Github-Actions中为无服务器部署正确设置pythonBin

Question

我正在尝试通过github操作部署一个简单的python lambda脚本。我一直在尝试弄清楚如何让github actions & serverless找到python3.6 (或python3.7)进行部署。

这是我的main.yml：

name: Deploy Lambda

# Controls when the action will run.  on:   # Triggers the workflow on push or pull request events but only for the master branch   push:
    branches: [ master ]

# Allows you to run this workflow manually from the Actions tab   workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel jobs:   # This workflow contains a single job called "deploy"   deploy:
# The type of runner that the job will run on
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: [3.6]
    env: #Setup environmental variables for serverless deployment
        AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
        AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v2
      
      - name: Set up Python 3.6
        uses: actions/setup-python@v2
        with:
          python-version: 3.6
      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
          echo "which python: `which python`"
          echo "which python3.6: `which python3.6`"
      
      - name: npm install dependencies
        run: npm install
        
      - name: Serverless
        uses: serverless/github-action@master
        with:
          args: deploy

这是我的serverless.yml

service: utilitybot 

provider:
  name: aws
  runtime: python3.6
  stage: prod
  region: us-east-1
  memorySize: 128

plugins:
  - serverless-wsgi
  - serverless-python-requirements
custom:
  wsgi:
    app: app.app
    packRequirements: false
    pythonRequirements:
      pythonBin: /opt/hostedtoolcache/Python/3.6.13/x64/bin/python3.6

functions:
  app:
    handler: wsgi_handler.handler
    events:
      - http: ANY /

下面是我尝试部署时的相关输出：

我尝试过没有pythonBin，各种版本的pythonBin，不同版本的python...我无法克服这个错误。当我执行哪个python3.6时，它会在路径中找到二进制文件，所以我搞不懂它在执行部署时为什么没有出现。

Answer 1

终于让它工作了。

我将运行时更改为3.7我从pythonBin中删除了python可执行文件(因此它只是/opt/hostedtoolcache/Python/3.6.13/x64/bin/ )我将矩阵策略保留在3.6，但有serverless安装3.7

最重要的是，我找到了一个运行得更好的公共镜像: mirrorhanyu/serverless-github-action-python@master

所以main.yml的末尾变成了

      - name: Serverless
        uses: mirrorhanyu/serverless-github-action-python@master
        with:
          args: deploy
