小编给大家分享一下go语言中如何在mac下brew升级golang，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
在命令行下直接运行：
brew upgrade go
补充：mac下更新delve调试go语言
概述
delve 是golang调试程序。但如果版本不配套， mac下goland 调试，step over会不起作用，直接变成执行完毕或者到下一个断点。 需要更新调试器delve解决。
go get安装
mac下安装delve，官方教程是两步。
$ xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates $ go get -u github.com/derekparker/delve/cmd/dlv
但go get 一直不返回。
homebrew 安装
zhouhh@/Users/zhouhh $ brew install go-delve/delve/delve Updating Homebrew... ==> Installing delve from go-delve/delve ==> Downloading https://github.com/derekparker/delve/archive/v1.0.0.tar.gz Already downloaded: /Users/zhouhh/Library/Caches/Homebrew/delve-1.0.0.tar.gz security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain. ==> Generating dlv-cert ==> openssl req -new -newkey rsa:2048 -x509 -days 3650 -nodes -config dlv-cert.cfg -extensions codesign_reqext -batch -out dlv-cert.cer -keyout dlv-cert.key ==> [SUDO] Installing dlv-cert as root ==> sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain dlv-cert.cer Last 15 lines from /Users/zhouhh/Library/Logs/Homebrew/delve/02.sudo: 2018-08-09 17:07:38 +0800 sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain dlv-cert.cer If reporting this issue please do so at (not Homebrew/brew or Homebrew/core): https://github.com/go-delve/homebrew-delve/issues These open issues may also help: Upgrade to delve fails https://github.com/go-delve/homebrew-delve/issues/20 /usr/local/Homebrew/Library/Homebrew/exceptions.rb:426:in `block in dump': undefined method `check_for_bad_install_name_tool' for #<Homebrew::Diagnostic::Checks:0x007fc5df858bd8> (NoMethodError) Did you mean? check_for_tap_ruby_files_locations from /usr/local/Homebrew/Library/Homebrew/exceptions.rb:425:in `each' from /usr/local/Homebrew/Library/Homebrew/exceptions.rb:425:in `dump' from /usr/local/Homebrew/Library/Homebrew/brew.rb:138:in `rescue in <main>' from /usr/local/Homebrew/Library/Homebrew/brew.rb:30:in `<main>'
这是因为证书有问题。 可以到homebrew缓存下载的delve里处理一下。
zhouhh@/Users/zhouhh $ cd $HOME/Library/Caches/Homebrew zhouhh@/Users/zhouhh/Library/Caches/Homebrew $ ls del* delve-1.0.0.tar.gz zhouhh@/Users/zhouhh/Library/Caches/Homebrew $ tar zxvf delve-1.0.0.tar.gz zhouhh@/Users/zhouhh/Library/Caches/Homebrew $ sh delve-1.0.0/scripts/gencert.sh Password:
再安装成功
zhouhh@/Users/zhouhh/Library/Caches/Homebrew $ CGO_ENABLED=1 brew install go-delve/delve/delve ==> Installing delve from go-delve/delve ==> Downloading https://github.com/derekparker/delve/archive/v1.0.0.tar.gz Already downloaded: /Users/zhouhh/Library/Caches/Homebrew/delve-1.0.0.tar.gz ==> dlv-cert is already installed, no need to create it ==> make build BUILD_SHA=v1.0.0 ==> Caveats If you get "could not launch process: could not fork/exec", you need to try in a new terminal. When uninstalling, to remove the dlv-cert certificate, run this command: $ sudo security delete-certificate -t -c dlv-cert /Library/Keychains/System.keychain Alternatively, you may want to delete from the Keychain (with the Imported private key). ==> Summary ? /usr/local/Cellar/delve/1.0.0: 6 files, 10.6MB, built in 13 seconds
安装成功
修改ide环境
安装完最新的 delve 后，如 brew install delve, 然后在IntelliJ或goland中点击
Help → Edit Custom Properties...
添加新行
dlv.path=/usr/local/bin/dlv
保存重启，解决step over(F8) 直接运行完毕的bug。
