GitHub Action 除錯案例

錯誤 1

錯誤資訊關鍵詞：cannot find package
問題描述：儘管專案實際上有正確引用 context 套件，依舊出現下列錯誤訊息

Error: db/sqlc/db.go:8:2: cannot find package "context" in any of:
    /opt/hostedtoolcache/go/1.2.2/x64/src/pkg/context (from $GOROOT)
    ($GOPATH not set)
make: *** [Makefile:20: test] Error 1
Error: Process completed with exit code 2.

解決方法：修改 Workflow
參考文件

Workflow 修改前

# 修改前
    - name: Set up Go
      uses: actions/setup-go@v3
      with:
        go-version: 1.20

Workflow 修改後

# 修改後
    - name: Set up Go
      uses: actions/setup-go@v3
      with:
        go-version-file: 'go.mod'
    - run: go version

錯誤 2

錯誤資訊關鍵描述：dial tcp [::1]:5432: connect: connection refused
問題描述：5432 是 PostgreSQL 預設埠號，錯誤訊息顯示連線遭到拒絕。這表示 Workflow 需要建立 PostgreSQL service。
解決方法：參考以下文件修改 Workflow。因為要在 Docker 容器內執行，所以也用得上 Docker Hub 的文件。

提示

Creating PostgreSQL service containers

Docker Hub: postgres

PostgreSQL service 設定範例

# 在 jobs: 以下找到適當位置編寫以下內容
    services:
      postgres:
        image: postgres:[your image version]
        # Provide the password for postgres
        env:
          POSTGRES_USER: root
          POSTGRES_PASSWORD: your_password
          POSTGRES_DB: your_db_name
        # Set health checks to wait until postgres has started
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5 
        # Maps tcp port 5432 on service container to the host
        ports:
          - 5432:5432
