SharePoint Framework：通过工作台进行测试时，客户端Webpart抛出错误

Question

我正在遵循下面的部署路径：

1. npm install -g yo gulp
2. npm install -g @ microsoft / generator-sharepoint
3. yo @ microsoft / sharepoint
4. gulp trust-dev-cert
5. gulp serve

在gulp serve命令之后我收到此错误： This page can't be displayed

请建议我们如何部署SharePoint Framework？
