botocore.exceptions.NoCredentialsError: Unable to locate credentials - Github Actions

Question

我正在尝试 运行 AWS SDK python 脚本使用 Github 操作。 Github 操作正在成功安装 Boto3 但脚本正在执行但出现以下错误：

错误：

Run python3 s3.py
Traceback (most recent call last):
  File "s3.py", line 5, in <module>
    response = s3.list_buckets()
  File "/opt/hostedtoolcache/Python/3.8.6/x64/lib/python3.8/site-packages/botocore/client.py", 
  File "/opt/hostedtoolcache/Python/3.8.6/x64/lib/python3.8/site-packages/botocore/signers.py", line 162, in sign
    auth.add_auth(request)
  File "/opt/hostedtoolcache/Python/3.8.6/x64/lib/python3.8/site-packages/botocore/auth.py", line 357, in add_auth
    raise NoCredentialsError
botocore.exceptions.NoCredentialsError: Unable to locate credentials
Error: Process completed with exit code 1.

目前已实施：

ListS3bucket.yml

name: Python package
on: [push]
jobs:
  deploy:
    name: sample code
    runs-on: ubuntu-latest

    steps:
    - name: checkout repo content
      uses: actions/checkout@v2 # checkout the repository content to github runner.
    - name: setup python
      uses: actions/setup-python@v2
      with:
        python-version: 3.8 
    - name: Upgrade PIP
      run: |
          /opt/hostedtoolcache/Python/3.8.6/x64/bin/python -m pip install --upgrade pip
    - name: install boto3
      run: |
          python -m pip install boto3   
    - name: execute script 
      env:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-east-1
      run: |
          python3 s3.py

s3.py

import boto3

# Retrieve the list of existing buckets
s3 = boto3.client('s3')
response = s3.list_buckets()

# Output the bucket names
print('Existing buckets:')
for bucket in response['Buckets']:
    print(f'  {bucket["Name"]}')

请指导。

根据评论。

解决方法是环境变量设置不正确。正确的是 AWS_ACCESS_KEY_ID、AWS_SECRET_ACCESS_KEY、AWS_DEFAULT_REGION，如 docs.
