忽略“导入而不使用”的编译时错误

I get this error:

src/huru/utils/utils.go:6:2: imported and not used: "fmt"

src/huru/utils/utils.go:9:2: imported and not used: "net/http"

when I have these unused imports:

import (
    "fmt"
    "net/http"
)

<rant> it turns out this a rather seriously annoying "feature" because some IDEs like VSCode will automatically remove unused imports which is f*cking annoying when you are about type the characters that will use the imports but you hit save first or what not. </rant>

Is there a way to ignore this compile error with a command line option? something like:

go install main --ignore-dumb-errors

Install additional tools

The source code for several Go tools (including goimports) is kept in the go.tools repository. To install all of them, run the go get command:

$ go get golang.org/x/tools/cmd/...

Or if you just want to install a specific command (goimports in this case):

$ go get golang.org/x/tools/cmd/goimports

To install these tools, the go get command requires that Git be installed locally.

You must also have a workspace (GOPATH) set up; see How to Write Go Code for the details.

$ goimports -help
usage: goimports [flags] [path ...]
  -cpuprofile string
        CPU profile output
  -d    display diffs instead of rewriting files
  -e    report all errors (not just the first 10 on different lines)
  -l    list files whose formatting differs from goimport's
  -local string
        put imports beginning with this string after 3rd-party packages; comma-separated list
  -memprofile string
        memory profile output
  -memrate int
        if > 0, sets runtime.MemProfileRate
  -srcdir dir
        choose imports as if source code is from dir. When operating on a single file, dir may instead be the complete file name.
  -trace string
        trace profile output
  -v    verbose logging
  -w    write result to (source) file instead of stdout
$ 

Run the goimports command with flag -w on your source code. It will fix your imports for you. It's how the Go Playground and IDEs fix imports.

For example,

$ cat imports.go
package main

import (
    "net/http"
)

func main() {
    fmt.Println("Hello, playground")
}

$ goimports -w imports.go
$ cat imports.go
package main

import "fmt"

func main() {
    fmt.Println("Hello, playground")
}
$ 

You can run it on an entire directory too.
