问题分析与解决方案 #

核心原因 #

错误no implicit conversion of String into Integer是CodeDeploy Agent（Ruby编写）的类型转换错误，根源是appspec.yml的files字段格式不符合要求：CodeDeploy要求files是数组结构，每个文件映射需用-标记为数组元素，当前配置将files写成了单个对象，导致Agent解析时类型不匹配。

修复步骤 #

1. 修正appspec.yml的files格式
   将files改为数组结构，调整后配置如下：

version: 0.0
os: linux
files:
  - source: /
    destination: /home/ubuntu/build
    overwrite: yes
    file_exists_behavior: OVERWRITE
permissions:
  - object: /home/ubuntu
    pattern: '**'
    owner: ubuntu
    group: ubuntu
hooks:
  BeforeInstall:
    - location: scripts/before-install.sh
      timeout: 300
      runas: root
  AfterInstall:
    - location: scripts/after-deploy.sh
      timeout: 300
      runas: root

2. 验证脚本执行（可选）
   在before-install.sh开头添加调试日志，确认文件路径有效性：

echo "当前工作目录: $(pwd)"
echo "目标目录: $DESTINATION_DIR"
echo "压缩文件路径: $ZIP_FILE_PATH"

3. 重启CodeDeploy Agent
   确保配置修改生效，执行命令：

sudo service codedeploy-agent restart
