  4. go env -w GOBIN="$(go env GOPATH)/bin"
  5. go env -w GO111MODULE="auto"
  6. go env -w GOPROXY="https://goproxy.io,https://proxy.golang.org,https://goproxy.cn,direct"
  8. echo "" >> ~/.zshrc
  9. echo "export GOPATH='/Users/${USER}/Desktop/Project/golang'" >> ~/.zshrc
  10. echo 'export PATH="${PATH}:${GOPATH}/bin"' >> ~/.zshrc
  1. go env -w GOOS="darwin"
  2. go env -w GOARCH="arm64"
  3. go env -w GOPATH="/Users/${USER}/Desktop/Project/golang"
  4. go env -w GOBIN="$(go env GOPATH)/bin"
  5. go env -w GO111MODULE="auto"
  6. go env -w GOPROXY="https://goproxy.io,https://proxy.golang.org,https://goproxy.cn,direct"
  8. echo "" >> ~/.zshrc
  9. echo "export GOPATH='/Users/${USER}/Desktop/Project/golang'" >> ~/.zshrc
  10. echo 'export PATH="${PATH}:${GOPATH}/bin"' >> ~/.zshrc
  1. go env -w GOOS="linux"
  2. go env -w GOARCH="amd64"
  3. go env -w GOPATH="/opt/golang"
  4. go env -w GOBIN="$(go env GOPATH)/bin"
  5. go env -w GO111MODULE="auto"
  6. go env -w GOPROXY="https://goproxy.io,https://proxy.golang.org,https://goproxy.cn,direct"
  8. echo "" >> ~/.bashrc
  9. echo "export GOPATH='/opt/golang'" >> ~/.bashrc
  10. echo 'export PATH="${PATH}:${GOPATH}/bin"' >> ~/.bashrc
  1. echo '' >> ~/.ssh/config
  2. echo 'Host e.coding.net' >> ~/.ssh/config
  3. echo '  Port 22' >> ~/.ssh/config
  5. echo '' >> ~/.gitconfig
  6. echo '[url "https://pt60y7hineu6:c3bccede2849bd974993b68ff55e23e13e2ca80e@e.coding.net/bitdesk/nodehub"]' >> ~/.gitconfig
  7. echo '  insteadOf = https://e.coding.net/bitdesk/nodehub' >> ~/.gitconfig
  9. go env -w GONOPROXY="e.coding.net"
  10. go env -w GONOSUMDB="e.coding.net"
  11. go env -w GOPRIVATE="e.coding.net"

获取环境变量：

  1. # 获取所有变量
  2. go env
  4. # 获取指定变量
  5. go env GOOS

还原环境变量：

  1. go env -u GOOS

模块管理

初始化项目：

  1. # 可执行
  2. go mod init
  4. # 库
  5. go mod init github.com/go-agumon/table

根据go.mod文件处理依赖关系（查缺补漏）

  1. go mod tidy

将依赖包复制到项目下的vendor目录

  1. go mod vendor

获取依赖关系

  1. go list -m all
