Download packages required for installation

Here is a demo to install MySQL driver package: github.com/go-sql-driver/mysql

Direct import shows that the package cannot be found. Use the command line tool at the bottom left to install MySQL driver

Use the go get command to install the package

Use go get github.com/go-sql-driver/mysql to install MySQL driver. After successful installation, the imported package in test.go turns green.

Supplement: Golan uses tips of go modules

Run go mod tidy with an error:

go: golang.org/x/[email protected]: unrecognized import path “golang.org/x/sys” (https fetch: Get https://golang.org/x/sys?go-get=1: dial tcp 216.239.37.1:443: c
onnectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed
to respond.)
go: error loading module requirements

The reason is that some dependencies are blocked in China. You can set a proxy here to solve the problem:

Enter the setting interface of Golan, file / settings / go / go module (VGO), and set the proxy as: https://goproxy.io 。

The above is my personal experience. I hope I can give you a reference, and I hope you can support developpaer. If you have any mistakes or don’t consider completely, please don’t hesitate to comment.
