refactor/importgraph: set env from packagestest.Export and check errors from Build

This test was written for GOPATH mode, and subsequently updated to use
packagestest at a time when GO111MODULE defaulted to "auto" (in this
case, off). As a result, the test was failing to set environment
variables relevant to the test, such as GO111MODULE=off.

The missing environment was causing errors that were subsequently
masked by a missing error check: the errors returned by
importgraph.Build were only read in an "if false" block.

This CL adds the missing environment variables and error checks. Using
the correct environment may or may not fix the observed test failures.

For golang/go#37823

Go Tools

PkgGoDev

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go install.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go install golang.org/x/tools/...@latest.

JS/CSS Formatting

This repository uses prettier to format JS and CSS files.

The version of prettier used is 1.18.2.

It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
