【问题描述】：

我正在通过 GitHub Actions: Publish to GitHub Packages 的培训学习 CD。

所以我创建了一个 Dockerfile，但它无法构建。我不明白为什么会发生这个错误。怎么解决？

到目前为止，我只使用机器人提供的源代码，所以很难想到一个简单的错字。

这是错误消息的摘录。

【解决方案1】：

您的.github/workflows/cd-workflow.yml 提及：

    - name: Build container image
      uses: docker/build-push-action@v1
      with:
        username: ${{github.actor}}
        password: ${{secrets.GITHUB_TOKEN}}
        registry: docker.pkg.github.com
        repository: CreatorOfWhileStudying/github-actions-for-packages/tic-tac-toe
        tag_with_sha: true

存储库部分与 docker 构建不兼容，如 logs for that action 所示：

错误来自 GitHub Action docker/build-push-action，如 issue 37。
尝试使用docker/build-push-action@v2。
