Goland: cannot call specific methods from imported package
问题
你好，Gopher们！
我在GoLand上遇到了一些问题，无论是在Windows还是Mac上。我正在尝试实现这个进度条 "github.com/schollz/progressbar"，但是包中并不是所有的方法都起作用。
例如，
bar := progressbar.New(someint)
可以正常工作。
但是如果我调用
bar := progressbar.NewOptions(someint), progressbar.OptionShowBytes(true))
那么编译器会报错，类似于
#./main.go:118:21: undefined: progressbar.NewOptions
#./main.go:118:56: undefined: progressbar.OptionShowBytes
这个包是没问题的。我已经重新导入了几次来进行检查。调整GO111MODULE也没有改变任何东西。
这是我的go env
GO111MODULE="on"
GOARCH="amd64"
GOBIN=""
GOCACHE="/Users/alex/Library/Caches/go-build"
GOENV="/Users/alex/Library/Application Support/go/env"

在谷歌上搜索这个错误也没有帮助。任何帮助将不胜感激。谢谢！

Hellо, fellow Gophers!
I have a trouble with import in GoLand, both on Windows and Mac. I am trying to implement this progress bar "github.com/schollz/progressbar", but not all the methods from the package work.
For example,
bar := progressbar.New(someint)
works perfecly.
But if I call
bar := progressbar.NewOptions(someint), progressbar.OptionShowBytes(true))
then the compiler throws errors like
>#./main.go:118:21: undefined: progressbar.NewOptions
>#./main.go:118:56: undefined: progressbar.OptionShowBytes
The package is okay. And I reimported it for a few times just to check. Messing around with GO111MODULE doesn't change anything.
Here is my go env
GO111MODULE="on"
GOARCH="amd64"

Googling the error didn't help either. Any help would be appreciated. Thank you!

以下是翻译好的内容：
"github.com/schollz/progressbar" 与以下源代码和模块文件一起使用。
bar, _ := progressbar.NewOptions(100), progressbar.OptionShowBytes(true)
模块文件
go 1.18
require github.com/schollz/progressbar/v3 v3.8.7
require (
github.com/mattn/go-runewidth v0.0.13 // indirect
github.com/mitchellh/colorstring v0.0.0-20190213212951-d06e56a500db // indirect
github.com/rivo/uniseg v0.3.1 // indirect
golang.org/x/crypto v0.0.0-20220722155217-630584e8d5aa // indirect

golang.org/x/term v0.0.0-20220722155259-a9ba230a4035 // indirect
)
英文:
The "github.com/schollz/progressbar" worked with following source and mod file.
bar, _ := progressbar.NewOptions(100), progressbar.OptionShowBytes(true)
mod file
go 1.18
