go - 超慢的编译时间

Question

我通常在计算机上使用Go，并且编译速度非常快(不到1秒)，但是不幸的是，在Visual Studio代码Go插件要求我安装一堆东西之后，Go变得非常慢，这是一个简单的代码，如下所示:

package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello")
}

执行时间超过10秒:

[Running] go run "c:\dev\workspace\go\test\src\main.go"
Hello

[Done] exited with code=0 in 45.596 seconds

[Running] go run "c:\dev\workspace\go\test\src\main.go"
Hello

[Done] exited with code=0 in 16.242 seconds

[Running] go run "c:\dev\workspace\go\test\src\main.go"
Hello

[Done] exited with code=0 in 14.759 seconds

[Running] go run "c:\dev\workspace\go\test\src\main.go"
Hello

[Done] exited with code=0 in 15.492 seconds

[Running] go run "c:\dev\workspace\go\test\src\main.go"
Hello

[Done] exited with code=0 in 16.047 seconds

我已经尝试过的:

卸载所有内容，然后重新安装；

将Go版本更改为1.4(它缩短了编译时间，但是
没什么大不了的，就像在这个版本中它编译成〜7
秒，仍然让它变慢了)

尝试了其他IDE(Idea)

现在，我正在使用最新的Go版本:

$ go version
go version go1.15.2 windows/amd64

我的“去环境”:

$ go env
set GO111MODULE=
set GOARCH=amd64
set GOBIN=
set GOCACHE=C:\Users\ticunha\AppData\Local\go-build
set GOENV=C:\Users\ticunha\AppData\Roaming\go\env

set GOROOT=c:\go
set GOSUMDB=sum.golang.org
set GOTMPDIR=
set GOTOOLDIR=c:\go\pkg\tool\windows_amd64
set GCCGO=gccgo
set AR=ar
set CC=gcc
set CXX=g++
set CGO_ENABLED=1
set GOMOD=
set CGO_CFLAGS=-g -O2
set CGO_CPPFLAGS=
set CGO_CXXFLAGS=-g -O2
set CGO_FFLAGS=-g -O2
set CGO_LDFLAGS=-g -O2
set PKG_CONFIG=pkg-config
set GOGCCFLAGS=-m64 -mthreads -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=C:\Users\ticunha\AppData\Local\Temp\1\go-build323480842=/tmp/go-build -gno-record-gcc-switches

有没有人经历过这个问题，可以让我对这个问题有所了解？谢谢!

首先检查问题是否仍然存在于命令行(CLI)
如果是这样，请通过在同一CMD session 中设置简化的PATH来确保这不是PATH问题:

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%
set PATH=%USERPROFILE%\go\bin;%PATH%
set PATH=c:\go\bin;%PATH%
