Where does go get install packages?

阅读更多关于 Where does go get install packages?

问题 I've been given instructions to run go get <some-remote-git-repo> which seems to succeed, but it's not clear to me where the package was installed to so I can run an executable from it.

Go is installed via Homebrew. 回答1: I found the missing clue by running brew info go , which says: ==> Caveats A valid GOPATH is required

为了能够愉快地进行golang编程，我们需要安装以下几样东西：包管理Homebrew 语言环境golang 版本管理git 虚拟器docker 编译器Goland 我将按照这个顺序叙述整个安装过程 docker 其实是可选的，它可以把应用程序打包为可移植的、自给自足的容器。这样一来，你就可以在本地生成golang程序的docker镜像，直接扔到测试环境，便可以进行测试了，不需要再进行代码上传，环境配置等操作了。如果你觉得暂时用不到，也可以先不装。 1、安装brew Homebrew有点类似于Linux操作系统中的apt-get（Ubuntu）、yum（yum），Mac的操作系统中使用它解决包依赖问题，套用官方的话来说： Homebrew 能干什么? 使用 Homebrew 安装 Apple 没有预装但你需要的东西。让我们开始安装吧！在命令行输入以下指令 fabric:~ fabric$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 出现以下内容，安装成功 ==> Installation successful! ==> Homebrew has enabled anonymous aggregate user behaviour

问题 Background I have a regex I want to run across multiple lines. My understanding is that OSX's grep can't handle this (please correct me if I'm wrong!). So after some Googling I found that PCRE would do what I want. I tried to install it with brew install pcre as a few sites suggested. It seems to have worked.
