Using VSCode with a conda go environment

README.md

$ conda create -n goenv go
$ conda activate goenv
(goenv) $ conda install -c conda-forge gxx_linux-64  # Required for the vscode go extension

Note the current goroot path

(goenv) $ go env GOROOT
/home/ec/miniconda3/envs/go/go

Add the path to vscode settings.json (Workspace or Global)

For workspace: config is saved in .vscode/settings.json

{
    "go.goroot": "/home/ec/miniconda3/envs/go/go",
}

Next install the Go plugin for VScode. It will prompt to install a few tools. Click on "Install All". However the installation of some tool will surely fail which needs to be installed manually like.

(goenv) $ go install -v github.com/cweill/gotests/[email protected]
(goenv) $ go install -v github.com/haya14busa/goplay/cmd/[email protected]
(goenv) $ go install -v github.com/go-delve/delve/cmd/dlv@latest
(goenv) $ go install -v honnef.co/go/tools/cmd/staticcheck@latest
(goenv) $ go install -v golang.org/x/tools/gopls@latest

The exact tools which failed and the corresponding command to install them can be found in the Output panel in VScode.

Another way with conda installed from scoop

This solves the issue:

go: cannot find GOROOT directory: 'go' binary is trimmed and GOROOT is not set

conda activate <env_name>
which go
conda conda env config vars set GOROOT="C:/Users/Administrator/scoop/apps/miniconda3/current/envs/<env_name>/go"

The PATH can also be appended this way

conda conda env config vars set PATH="C:\Users\Administrator\go\bin;%PATH%"

Warning

Apparently setting the PATH this way doesn't work. The %PATH% variable is not expanded.
