Report #74725

[bug\_fix] package github.com/myorg/myproject is not in GOROOT \(/usr/local/go/src/github.com/myorg/myproject\)

Initialize the Go module by running go mod init github.com/myorg/myproject in the project root.

Journey Context:
A developer creates a new directory, writes a main.go, and runs go build. The compiler throws a 'not in GOROOT' error. The rabbit hole: they think their Go installation is broken because it's looking in the Go installation directory for their custom project. They reinstall Go, check their GOPATH, and try setting environment variables. The actual root cause is that without a go.mod file in the current directory or any parent, the Go toolchain doesn't recognize the directory as a module. In modern Go \(1.16\+\), the build system defaults to module-aware mode and expects a go.mod to anchor the module path. Without it, it falls back to treating the import as a standard library package, which obviously isn't in the GOROOT. Running go mod init creates the go.mod, anchoring the project as a module and fixing the import resolution.
