[Container] 2020/10/29 16:48:39 Command did not exit successfully aws --version exit status 1

The failure occurs in the PRE_BUILD.

And this is my spec build file: buildspec-cd.yml

pre_build:
    commands:
      - AWS_REGION=${AWS_DEFAULT_REGION}
      - COMMIT_HASH=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
      - IMAGE_VERSION=${COMMIT_HASH}
      - REPOSITORY_URI=${CONTAINER_REGISTRY}/${APPLICATION_NAME}
      - aws --version
      - echo Logging in to Amazon ECR...
      - $(aws ecr get-login --region $AWS_DEFAULT_REGION --no-include-email)

The codebuild was working correctly and nothing has been changed. Only stopped working.

Reading this GitHub issue #2596. i fixed my error.

Just before the PRE_BUILD section, I added this line to my buildspec-cd.yml file:

pip3 install --upgrade awscli

install:
    commands:
      - pip3 install awsebcli --upgrade
      - eb --version
      - pip3 install --upgrade awscli

    pre_build:
      commands:
      - AWS_REGION=${AWS_DEFAULT_REGION}
      - COMMIT_HASH=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
      - IMAGE_VERSION=${COMMIT_HASH}
      ...
