运行简单的 go 代码时遇到错误

Question

我正在尝试运行一个简单的 go 代码

package main

import (

    "log"

    "net/http"

    "fmt"

)

func homePage(w http.ResponseWriter, r *http.Request) {

}

func handleRequest() {

    http.HandleFunc("/", homePage)

    log.Fatal(http.ListenAndServe(":8081", nil))

}

func main() {

    handleRequest()

}

Go 版本：go1.17.5 darwin/arm64

macOS：蒙特雷 12.1

错误信息：

# runtime/cgo

ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks//CoreFoundation.framework/CoreFoundation.tbd' for architecture arm64

clang-10: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

以下命令帮助了我。尝试重新安装 Xcode 命令行工具并升级 llvm 和 gcc。$ brew upgrade llvm$ brew upgrade gcc$ sudo rm -rf /Library/Developer/CommandLineTools$ xcode-select --install
