go语言-在mac下brew升级golang_Golang

在命令行下直接运行：

1	`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。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。如有错误或未考虑完全的地方，望不吝赐教。
