AWS CodeBuild error: Expected Phases to be non-empty at line 2

Question

我正在尝试在 AWS CodeBuild 上部署我的 Angular 8 应用程序。但是我得到这个错误：DOWNLOAD_SOURCE Failed YAML_FILE_ERROR: Expected Phases to be non-empty at line 2

尽管我在创建 S3 存储桶时授予了所有 public 访问权限，但构建日志事件中也出现了 ACCESS DENIED 错误。 COMMAND_EXECUTION_ERROR: Error while executing command: aws s3 cp dist s3://${S3_BUCKET} --recursive. Reason: exit status 1

我按照 here 所述向我的 S3 存储桶添加了访问策略，但这没有帮助。

我的 buildspec.yml 文件如下所示，阶段列表不为空：

version: 0.1
phases:
  install:
    commands:
      - npm install -g @angular/cli
  build:
    commands:
      - npm install
      - ng build --prod --configuration=${BUILD_ENV}
  post_build:
    commands:
      - aws s3 cp dist s3://${S3_BUCKET} --recursive
      - aws configure set preview.cloudfront true
      - echo ${S3_BUCKET}
artifacts:
  files:
    - '**/*'
base-directory: 'dist*'
discard-paths: yes

我以前从未使用过 YAML，我做错了什么？

以下是构建日志事件：

已解决： 在下面 Marcin 的回答后，我在 CodeBuild 中附加到我的构建项目的服务角色 - 构建现在成功了！：

Answer 1

命令 aws s3 cp dist s3://${S3_BUCKET} --recursive 失败，因为与您的代码构建项目关联的角色没有对 ${S3_BUCKET}.

的 s3:PutObject 权限

您提供给 S3 存储桶的 link 策略是错误的，因为它应该允许访问 CodeBuild 正在使用的 IAM 角色，而不是 IAM 用户。

要解决这个问题，您有两个选择：

向用于构建项目的 CodeBuild role 添加所需的权限。 link 还显示了具有 S3 权限的示例 CodeBuild 角色。
将角色添加到存储桶策略。

你没有发布你使用的Bucket Policy，所以我只是举个例子：

{
    "Id": "MyPolicyForCodeBuild",
    "Version": "2012-10-17",
    "Statement": [
        {

            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::<your-bucket>/*",
