Report #57862

[bug\_fix] package is not in GOROOT \(/usr/local/go/src/\)

Ensure the import path matches the module path defined in go.mod \(e.g., \`github.com/me/myapp/pkg\`\), and that you are running the build from within the module directory.

Journey Context:
A developer refactors a monorepo and creates a new internal package under \`myapp/internal/foo\`. They import it as \`myapp/internal/foo\` and run \`go build\`. The compiler spits out 'package myapp/internal/foo is not in GOROOT'. The developer is baffled—they know the package isn't in GOROOT, it's in their project\! They try setting GOPATH, but the error persists. The root cause is that the Go compiler, when it sees an import path that doesn't look like a URL \(no dots\), assumes it must be a standard library package and looks exclusively in GOROOT. Because the module in go.mod is named \`github.com/me/myapp\`, the internal package must be imported as \`github.com/me/myapp/internal/foo\` to be resolved within the module. Fixing the import path to match the module prefix resolves the GOROOT lookup fallback.
