config go env​

config proxy for go​

resolution 1. use env variable:

# resolution 1. use env variable
GOPROXY=$PROXY

resolution 2. use alias:

alias go='http_proxy=$PROXY https_proxy=$PROXY no_proxy=localhost,127.0.0.0/8,::1 go'

see: - How do I configure go command to use a proxy? - Stack Overflow

resolution 1: go env -w​

⚠️ go env -w needs go version >= 1.13

go env -w GOPROXY=https://goproxy.io,direct
# Set environment variable allow bypassing the proxy for selected modules
go env -w GOPRIVATE=*.corp.example.com
go env -w GO111MODULE=on

resolution 2: config ~/.profile​

cat << EOF >> ~/.profile
# Enable the go modules feature
export GO111MODULE=on
# Set the GOPROXY environment variable
export GOPROXY=https://goproxy.io
EOF
