先决条件：设置 AWS Amplify CLI。
1。项目初始化。
amplify init：在本地和远程设置 AWS Amplify。
注意：未找到放大初始化命令
1)`npm install -g @aws-amplify/cli` - ### install the Amplify CLI ###
2)`curl -sL https://aws-amplify.github.io/amplify-cli/install | bash && $SHELL` ### configured $Path correctly ###
3)`amplify init` ###Try Amplify init###
