go語言-在mac下brew升級golang

更新時間：2021年04月25日 14:31:09 作者：qauzy

這篇文章主要介紹了go語言-在mac下brew升級golang，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

在命令行下直接運(yùn)行：

brew upgrade go

補(bǔ)充：mac下更新delve調(diào)試go語言

概述

delve 是golang調(diào)試程序。但如果版本不配套， mac下goland 調(diào)試，step over會不起作用，直接變成執(zhí)行完畢或者到下一個斷點(diǎn)。需要更新調(diào)試器delve解決。

go get安裝

mac下安裝delve，官方教程是兩步。

$ 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 安裝

These open issues may also help:

這是因?yàn)樽C書有問題。可以到homebrew緩存下載的delve里處理一下。

再安裝成功

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).
