IDE 是 Visual Studio 代码。这是我打开调试器时的日志：
# _/Users/leon/Documents/Projects/GoLang/TutorialLearningGoForWebDevelopment

去版本：
go version go1.10.3 darwin/amd64
macOS 版本：
Mojave Version 10.14 Beta (18A353d)
钻研版：
Delve Debugger
Version: 1.0.0
Build: $Id: c98a142125d0b17bb11ec0513bde346229b5f533 $

launch.json几乎是自动生成的，仅更改了端口：

在这里找到一些类似的问题线程，我没有找到解决方案。
我也安装了go1.11beta3，但我不知道如何在 VSCode 调试方面将其设为默认值。
对症状的更准确描述：
错误不是由Delve侧面引起的，而是源于go程序的第一行：package main
以防万一有人可能需要阅读代码，我将整个文件包括在下面：
