go语言-在mac下brew升级golang

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...

these open issues may also help:

 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

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。如有错误或未考虑完全的地方，望不吝赐教。
