配置编译环境

sudo mkdir -p /opt/$USER
sudo chown $USER:$USER /opt/$USER

cd /opt/$USER
version=1.20.2
if [ ! -f go${version}.linux-amd64.tar.gz ]; then
    wget https://studygolang.com/dl/golang/go${version}.linux-amd64.tar.gz
fi
rm -rf /opt/$USER/go${version} && mkdir -p /opt/$USER/go${version}
tar zxf go${version}.linux-amd64.tar.gz -C /opt/$USER/go${version}/ --strip-components=1
rm -f go && ln -sf go${version} go

# export PATH="/opt/$USER/go/bin:$PATH"
. ~/.bashrc
env | grep PATH | grep 'go/bin'
if [ $? -ne 0 ]; then
    echo "export PATH=\"/opt/$USER/go/bin:\$PATH\"" >> ~/.bashrc
fi

# check
which go
go version

MacOS

初始安装

brew search go
brew install [email protected]

其它版本

• 1.20.2

go install golang.org/dl/go1.20.2@latest
go1.20.2 download
go1.20.2 version
go1.20.2 env GOROOT

export PATH="$(go1.20.2 env GOROOT)/bin:$HOME/go/bin:$PATH"
go version

• 1.17.8

go get golang.org/dl/go1.17.8
go1.17.8 download
go1.17.8 version
go1.17.8 env GOROOT
export PATH="$(go1.17.8 env GOROOT)/bin:$HOME/go/bin:$PATH"
go version

注：编辑shell配置如~/.zshrc，调整PATH
export PATH="$HOME/sdk/go1.17.8/bin:$HOME/go/bin:$PATH"

Q&A

go多版本切换

1. gvm
2. multi GOROOT
3. brew switch

gvm主要是在LINUX/UNIX系统上管理Golang套件版本的．
Mac OSX最好使用的homebrew
[Golang]透过brew来做Golang的版本切换
