golang環境安裝問題集錦

直入主題，環境Mac os Mojave 10.14.6

配置環境變量

export GOROOT=$HOME/Development/go
export GOPATH=$HOME/Development/path 
export PATH=$PATH:$HOME/Development/go/bin:/$HOME/Development/path/bin
#建議直接設置爲go1.4，後續會創建go1.4目錄，由於之前編譯一直設置的go，走了很多彎路。
export GOROOT_BOOTSTRAP=$HOME/Development/go1.4

編譯

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

報錯如下

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

根據github提示執行

#從源代碼構建Go1.4
git checkout -b 1.4.3 go1.4.3
cd src
./all.bash
#複製~/go到$GOROOT_BOOTSTRAP（~/go1.4默認情況下）`
cp ~/go ~/go1.4 -rf
#從源代碼構建Go1.6
cd ~/go
git clean -dfx
git checkout -b 1.6 go1.6
cd src
./all.bash

報錯如下

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

安裝

xcode-select --install

再次編譯

./all.bash

報錯如下

Building Go cmd/dist using /Users/zhangzhichao/Development/go1.4.
Building Go toolchain1 using /Users/zhangzhichao/Development/go1.4.
Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1.

再次編譯

git clean -df

最終編譯完成

##### ../misc/cgo/testcshared
SKIP - short mode and $GO_BUILDER_NAME not set

##### ../misc/cgo/testplugin

##### API check
Go version is "go1.13rc1", ignoring -next /Users/zhangzhichao/Development/go/api/next.txt

ALL TESTS PASSED

go新版本會依賴go1.4版本構建，走了好多彎路，之前不停的切換分支修改環境變量，後來突然想通，需要同時擁有兩個版本。
