Question

我正在尝试从 learn go with tests 中学习 select 语句。就在此之前，我将 macOS 升级到 Big Sur 11.4 版。现在我正在尝试在 VS Code 中运行以下测试。

package racer
import(
    "time"
    "net/http"
)

//Racer ...
func Racer(a,b string)(winner string){
    startA :=time.Now()
    http.Get(a)
    Aduration:=time.Since(startA)
    startB :=time.Now()
    http.Get(b)
    Bduration:=time.Since(startB)
    if Aduration < Bduration{
        return a
    }
    return b
}

测试是

package racer
import(
    "time"
    "net/http"
)

//Racer ...
func Racer(a,b string)(winner string){
    startA :=time.Now()
    http.Get(a)
    Aduration:=time.Since(startA)
    startB :=time.Now()
    http.Get(b)
    Bduration:=time.Since(startB)
    if Aduration < Bduration{
        return a
    }
    return b
}

这是我的 go env

当我尝试使用 go test 运行此测试时，它返回错误消息 runtime/cgo ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libpthread.tbd' for architecture x86_64 clang-10: error: linker command failed with exit code 1 (use -v to see invocation)

在做了一些在线研究之后，我使用 sudo rm -rf /Library/Developer/CommandLineTools 删除了我的命令行工具，我重新启动了我的系统，出现了一个弹出窗口，要求我再次下载命令行工具。我安装了它们。当我尝试使用 go test 再次测试代码时，它返回错误 runtime/cgo _cgo_export.c:3:10: fatal error: 'stdlib.h' file not found。我做了 xcode-select --install 但它已经安装了。在升级之前，我没有遇到任何这些问题。升级后可能会发生一些变化。我能帮我解决这个问题吗？

_cgo_export.c:3:10: 致命错误：升级到 mac OS Big Sur 后在 VS Code 中运行 go test 时找不到“stdlib.h”文件
