go语言踩坑

no required module provides package 报错：

PS E:\go\go-webkit-master> go run example/webview.go
example\webview.go:5:2: no required module provides package github.com/mattn/go-gtk/gtk: go.mod file not found in current directory or any parent directory; see 'go help modules'

执行：

go env -w GO111MODULE=auto
go mod init example
go get xxxx 缺失的mod

之后在运行go程序即可

go run example/webview.go

若中间出现：

PS E:\go\go-webkit-master> go get github.com/mattn/go-webkit/webkit
# pkg-config --cflags  -- pango
pkg-config: exec: "pkg-config": executable file not found in %PATH%
# pkg-config --cflags  -- glib-2.0 gobject-2.0
pkg-config: exec: "pkg-config": executable file not found in %PATH%
