GO语言打开文件失败，runtime error

Question

打开文件直接失败了，是接受文件内容的变量空间不够嘛？这种情况不应该出现在打开文件时吧，大佬们，救救~

import (
    ...

    "github.com/tealeg/xlsx"
)


func main() {
    ...
    xlFile, err := xlsx.OpenFile(file.Name())
                if err != nil {
                    fmt.Printf("open file: %s --> failed: %s\n", file.Name(), err)
                }

open file: test.xlsx --> failed: runtime error: index out of range [63] with length 0
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x30 pc=0x51d3db]
