goland导包报红
1. 原理
import的包有两类：
（1）在go.mod中有地址的，这种需要拉到gopath/pkg下
（2）没在go.mod的，这种在项目里，import的路径需要从path路径(即：/go/src/，gopath为go寻找的根路径)为根路径可以找到的：import github.com/CardInfoLink/quickpay/internal/ins，对应项目所在路径：/go/src/github.com/CardInfoLink/quickpay
2. 以前的笔记
要打开项目的直接目录：trunk
若打开上级的话则报红
可能有关这些配置文件的原因
go mod
go mod tidy
goland 还是报红的话 goland Preference->Go->Go Modules(vgo) -> Enable Go Modules(vgo)intergration
jrw@wangfy:~/code/community/article$ go mod
Go mod provides access to operations on modules.
Note that support for modules is built into all the go commands,
not just 'go mod'. For example, day-to-day adding, removing, upgrading,
and downgrading of dependencies should be done using 'go get'.
See 'go help modules' for an overview of module functionality.
Usage:
go mod <command> [arguments]
The commands are:
download download modules to local cache
edit edit go.mod from tools or scripts
graph print module requirement graph
init initialize new module in current directory
tidy add missing and remove unused modules
vendor make vendored copy of dependencies
verify verify dependencies have expected content
why explain why packages or modules are needed
Use "go help mod <command>" for more information about a command.GO111MODULE=on
export GOPROXY=https://goproxy.io
sudo chmod -R 777 /工作目录 (-R：是指几连医用到目录里所有子目录和文件；777：是指所有用户都拥有的最高权限）
go mod tidy
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
