VSCode: Could not import Golang package

Question

I'm writing a Go project inside my GoPath, and i'm using the Redigo package for connecting to a Redis Server. The application runs fine, however in VSCode there is this annoying error on package import, which is preventing VSCode from giving intellisense suggestions

Could not import github.com/gomodule/redigo/redis (no package data for import path github.com/gomodule/redigo/redis)

This is my VSCode settings.json

{     "editor.fontSize": 14,     "editor.formatOnPaste": true,     "editor.multiCursorModifier": "ctrlCmd",     "editor.snippetSuggestions": "top",     "extensions.ignoreRecommendations": false,     "workbench.statusBar.visible": true,     "workbench.iconTheme": "vscode-great-icons",     "files.autoSave": "afterDelay",     "go.useLanguageServer": true,     "go.alternateTools": {         "go-langserver": "bingo"     },     "go.toolsEnvVars": {         "GO111MODULE": "on"     },     "go.languageServerExperimentalFeatures": {         "autoComplete": true,         "documentSymbols": true,         "findReferences": true,         "format": true,         "goToDefinition": true,         "goToTypeDefinition": true,         "hover": true,         "signatureHelp": true,         "rename": true,         "workspaceSymbols": true,     },     "go.lintTool": "golangci-lint",     "go.lintFlags": [         "--fast",         "-E", "goimports",         "-E", "gocritic",         "-E", "gocyclo",         "-E", "gosec",         "-E", "maligned",         "-E", "scopelint",         "-E", "interfacer",         "-E", "goconst",         "-E", "unconvert",         "-E", "unparam",         "-E", "prealloc",         "-E", "varcheck",     ],     "go.formatTool": "goimports",     "editor.minimap.enabled": false,     "breadcrumbs.enabled": false,     "git.autofetch": true,     "workbench.startupEditor": "newUntitledFile",     "explorer.confirmDelete": false,     "git.enableSmartCommit": true,     "git.confirmSync": false,     "window.zoomLevel": 0,     "explorer.confirmDragAndDrop": false } 

I already have the GO111MODULE env var set to on, this is the output of go env

set GOARCH=amd64 set GOBIN=C:\Users\Francesco\Go\bin set GOCACHE=C:\Users\Francesco\AppData\Local\go-build set GOEXE=.exe set GOFLAGS= set GOHOSTARCH=amd64 set GOHOSTOS=windows set GOOS=windows set GOPATH=C:\Users\Francesco\Go set GOPROXY= set GORACE= set GOROOT=c:\go set GOTMPDIR= set GOTOOLDIR=c:\go\pkg\tool\windows_amd64 set GCCGO=gccgo set CC=gcc set CXX=g++ set CGO_ENABLED=1 set GOMOD=C:\Users\Francesco\Go\src\test\go.mod set CGO_CFLAGS=-g -O2 set CGO_CPPFLAGS= set CGO_CXXFLAGS=-g -O2 set CGO_FFLAGS=-g -O2 set CGO_LDFLAGS=-g -O2 set PKG_CONFIG=pkg-config set GOGCCFLAGS=-m64 -mthreads -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=C:\Users\FRANCE~1\AppData\Local\Temp\go-build928398422=/tmp/go-build -gno-record-gcc-switches 

What should I change to make this work?

Answer 1

This happens to me in a few specific situations. This is my troubleshooting process :

1. Did you run go get github.com/gomodule/redigo/redis?

2. Sometimes I have a similar issue when I open my editor in a root different than my project.

.  <- editor open here |  |_Folder   | main.go 

3. Make sure your tools are up to date: run ctrl + shift + p, type Go and chose Install/Update tools.

4. Try moving your project out of the GOPATH, and setting up go.mod for it.

5. Restart the editor

Answer 2

I had a same sort of issue with a different package (on mac),

1. Update the go tools - ctrl + shift + p or cmd + shift + p and update/install go tools
2. Restart VScode
