go: cannot find main module, but found .git config to create a module there, run: go mod

go: cannot find main module, but found .git/config to create a module there, run: go mod

This problem occurred in a monorepo opened in VSCode. The repo has many services placed in isolated directories with respective go.mod files.

I realized from various sources that the problem is from two places:

  1. Move the mono repo under $GOPATH/src.
  2. The ~/.zshrc or ~/.bashrc must be as follows: 
    export GOPATH=$HOME/go/
export GOROOT=/usr/local/go

export PATH="$GOROOT/bin:$PATH"
export PATH="$PATH:$GOPATH/bin"

Do not add any other variable that affects gopls such as GO111MODULE=on.

How to Add Multiple Directories in GOPATH with VSCode?

Since go versions keep moving up, maintaining GOPATH inside a Go installation path is a pain.

export GOPATH=/home/a-user/go/1.14.9

ls /home/a-user/go/1.14.0/src 
bitbucket.org github.com    go.uber.org   golang.org    gopkg.in

Adding multiple directories in GOPATH

  1. Create a directory e.g. for work 
    mkdir $HOME/mywork
  2. GOPATH assumes a structure in the directory, so create three directories inside. 
    ls $HOME/mywork
bin pkg src
  3. You will do all your personal development work inside $HOME/mywork/src. 
    ls $HOME/mywork/src
project-01
  4. Append .bashrc or .zshrc (append is a must, it won’t work otherwise because GOPATH is preset by goenv) 
    # keep it at the end of the file
export GOENV_ROOT="$HOME/.goenv"
export PATH="$GOENV_ROOT/bin:$PATH"
eval "$(goenv init -)"

export PATH="$GOROOT/bin:$PATH"
export PATH="$PATH:$GOPATH/bin"
export PATH="$PATH:$HOME/bin"

# add personal directory
export GOPATH="$GOPATH:$HOME/mywork/"
  5. Open the directory $HOME/mywork/src/project-01 in VSCode workspace.
  6. If you have the VSCode extension for Go installed, restart VSCode.

If go to implementation doesn’t work, ensure that go is installed properly with src directory.

ls $HOME/go/1.14.0/ 
bin pkg src

That’s all folks!

VSCode Plugins for Golang Development

  1. Rich Go language support for Visual Studio Code
  2. Theme: Dark Knight: A simple dark theme for Golang projects
  3. Git Blame & Git History
  4. Postfix templates for Golang
  5. Adds go to implementation on context menu
  6. All-language autocompleter — TabNine uses machine learning to help you write code faster.

This is a minimal list of Go development extensions in my opinion.

vscode: How to Customize a Settings and Theme

You can change almost everything in vscode settings. I wasn’t happy with terminal settings, so found very useful hints on changing them.

A complete list of coding font is available here.

My current settings.json is as follows:
