YAML_FILE_ERROR消息：容器标签的数量错误，预期为1

Question

我是AWS CodePipeline的新手，并且在AWS CodeBuild上遇到此错误

“ YAML_FILE_ERROR消息：容器标签的数量错误，预期为1”

我为aspnet core 2.1项目设置了带有CodeBuild和CloudFormation的AWS CodePipeline。这是我的buildspec.yml

 {
  "name": "Utility",
  "source": {
    "type": "S3",
     "location": "<location>/windows-dotnetcore.zip"
 },
    "artifacts": {
    "type": "S3",
    "location": "<location>",
    "packaging": "ZIP",
    "name": "Utility.zip"
  },
  "environment": {
  "type": "LINUX_CONTAINER",
  "image": "aws/codebuild/dot-net:core-2.1",
  "computeType": "BUILD_GENERAL1_SMALL"
 },
 "serviceRole": "<value>",
 "encryptionKey": "<value>"
 }

Answer 1

当我从yml中省略了第一条“版本”行时，这发生在我身上：

version: 0.2

Answer 2

当我将一个空白的 buildspec.yml 签入 CodeCommit 时，我收到了此错误。一旦我用这样的东西更新了它，我就可以开始了：

version: 0.2

phases:
  install:
    commands:
      - echo Installing Mocha...
      - npm install -g mocha
  pre_build:
    commands:
      - echo Installing source NPM dependencies...
      - npm install unit.js
  build:
    commands:
      - echo Build started on `date`
      - echo Compiling the Node.js code
      - mocha HelloWorld.js
  post_build:
    commands:
      - echo Build completed on `date`
artifacts:
  files:
    - HelloWorld.js

出于好奇，我认为这可能是格式错误，但我尝试检查一些垃圾文本并收到以下错误：

Phase context status code: YAML_FILE_ERROR Message: stat
