About new usage of golang gopath

The following tutorial column will introduce you to the new usage of golang gopath. I hope it will be helpful to friends in need! New usage of golang gopath

Since using golang to develop projects, golang project code dependency issues have been bothering me, mainly on gopath The unclear usage has led to a very confusing project structure. Recently, I suddenly thought of a good usage of gopath. After careful study, it is indeed feasible. I wrote it down here and shared it for your reference.

Requirements

First of all The project structure I want to achieve is to have a separate directory to store third-party open source libraries, and then my own multiple golang projects can share these open source libraries.

In addition, I don’t want to set the global gopath directory every time I switch projects.

Implementation method

I am using a mac environment. For other environments, please study the configuration method yourself. It should be similar.

First set the environment variables

vi ~/.bash_profile
export GOPATH=/work/go/gopath

Only set the shared third-party open source library storage directory here, and the third-party libraries installed by go get will be stored here

In When compiling the project, manually add the project and directory after GOPATH

echo $GOPATH

/work/go/gopath

export GOPATH=$ GOPATH:/work/go/loolgame

echo $GOPATH

/work/go/gopath:/work/go/loolgame

The project directory must be shared After the open source directory

Finally execute the compilation command

go install server

How to set it under the compiler

In the compiler environment we can set the gopath environment in the compiler To achieve the same purpose as above

intelij IDEA

Configuration environment

Compile

go get golang.org/x/net Installation failure solution

Installation command: go get golang.org/x/net, error message: package golang.org/x/net: unrecognized import path "golang.org/x/net", package document address: https://godoc.org/golang.org/....

This problem is mainly because golang.org is blocked and cannot be accessed

The simple solution is

Download from https://github.com/golang/net, and then change the directory to golang .org/x/net. Then, everything is fine.

ps: If you have git, you can directly go get github.com/golang/net. If not, you can download it manually and put it in the src directory.
