Why Are My Go Commands Hanging?

Hanging Go Commands: Troubleshooting Unmounted GOPATH

Have you recently encountered a perplexing issue where the "go run," "go get," and other Go commands remain stuck in an infinite loop, showing no signs of completion? If so, adding the "-x" flag only reveals the build stage, leaving you baffled.

Problem Investigation

After an initial troubleshooting attempt, you may have discovered that this problem surfaced abruptly after a system restart, despite previous successful executions of Go commands.

Solution

The culprit, surprisingly, lies in the GOPATH environment variable. If your GOPATH points to a folder that should mount automatically during boot up but fails to do so, you might not receive any explicit error message. In this scenario, the Go process simply hangs indefinitely.

To resolve this issue, verify that your GOPATH is set to a valid and mountable path. If necessary, correct the GOPATH setting or ensure that the desired drive is properly mounted before executing any Go commands.

By addressing this potential error source, you can restore the proper functionality of Go commands and prevent them from hanging indefinitely due to an unmounted GOPATH.
