panic: /debug/requests is already registered. You may have two independent copies of golang.org/x/net/trace in your binary, trying to maintain separate state. This may involve a vendored copy of golang.org/x/net/trace.

解决办法：olang.org/x/net/trace这个重复了，删除所有的引用的或者系统的olang.org/x/net/的trace 只保留一个即可。注意要查看项目引用的项目是否也有

exec: “gcc”: executable file not found in %PATH%

解决办法：
下载 mingw ，地址： https://sourceforge.net/projects/mingw-w64/，
安装选择x86_x64
设置环境变量：C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin（安装路径）
