Due to network problems, some dependent tools cannot be installed properly, so manual installation is required.
Here are the steps for manually installing the tool:
GOPATH

in % % \ SRC \ directory and establish a path \ x golang.org into GOPATH%\src\golang.org % \ x , download tools, source code git clone https://github.com/golang/tools.git tools after the completion of the clone, A Tools folder will be generated so that the source code for the tool is ready to execute under % goPath %

 go install github.com/ramya-rao-a/go-outline go install github.com/acroca/go-symbols go install golang.org/x/tools/cmd/guru go install golang.org/x/tools/cmd/gorename go install github.com/rogpeppe/godef go install github.com/sqs/goreturns go install github.com/cweill/gotests/gotests 

Separate processing golint golint source is located in the https://github.com/golang/lint , enter GOPATH%\src\golang.org % \ x after the execution of git clone https://github.com/golang/lint download golint GOPATH need source code to the % % , the execution of go install github.com/golang/lint/golint
This completes the installation of the tools on which VS Code's Golang plug-in depends.
