• 多个版本管理

1.下载go1.16

➜  bin pwd
/Users/xxxx/go-dev/bin
➜  bin go get golang.org/dl/go1.15.8
go: finding golang.org/dl latest
➜  bin ll
total 28816
-rwxr-xr-x  1 xxxxx  staff   7.0M  2 20 18:33 go1.15.8
-rwxr-xr-x  1 xxxxx  staff   7.0M  2 20 18:31 go1.16

确保可执行路径已经添加到PATH中.

# go
export GOPATH="${HOME}/go-dev"
# GOROOT是GO的安装路径
export GOROOT="$(brew --prefix golang)/libexec"
export PATH="$PATH:${GOPATH}/bin:${GOROOT}/bin"

新开终端/或者重新激活一下zshrc

2.下载go1.16 同时配置go1.16 env GOROOT
