golang环境安装问题集锦

直入主题,环境Mac os Mojave 10.14.6

配置环境变量

export GOROOT=$HOME/Development/go
export GOPATH=$HOME/Development/path 
export PATH=$PATH:$HOME/Development/go/bin:/$HOME/Development/path/bin
#建议直接设置为go1.4,后续会创建go1.4目录,由于之前编译一直设置的go,走了很多弯路。
export GOROOT_BOOTSTRAP=$HOME/Development/go1.4

编译

git clone https://github.com/golang/go.git 
cd go/src
./all.bash

报错如下

Set $GOROOT_BOOTSTRAP to a working Go tree >= Go 1.4.

根据github提示执行

#从源代码构建Go1.4
git checkout -b 1.4.3 go1.4.3
cd src
./all.bash
#复制~/go到$GOROOT_BOOTSTRAP(~/go1.4默认情况下)`
cp ~/go ~/go1.4 -rf
#从源代码构建Go1.6
cd ~/go
git clean -dfx
git checkout -b 1.6 go1.6
cd src
./all.bash

报错如下

missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

安装

xcode-select --install

再次编译

./all.bash

报错如下

再次编译

git clean -df

最终编译完成

go新版本会依赖go1.4版本构建,走了好多弯路,之前不停的切换分支修改环境变量,后来突然想通,需要同时拥有两个版本。
