权限被拒绝使用Go在Mac中写入文件wkhtmltopdf

如何解决权限被拒绝使用Go在Mac中写入文件wkhtmltopdf

我有一些与wkhtmltopdf驱动程序权限相关的奇怪异常。我在Mac OS上。

我在仓库中有下一个代码：https://github.com/PumpkinSeed/htmltopdf

当我尝试运行测试用例时：

package htmltopdf

import (
    "testing"

    "github.com/stretchr/testify/assert"
)

func TestExample1(t *testing.T) {
    err := Example("examples/invoice-template-1/invoice.html","./invoice1.pdf")

    assert.NoError(t,err)
}

func TestExample2(t *testing.T) {
    err := Example("examples/invoice-template-2/invoice.html","./invoice2.pdf")

    assert.NoError(t,err)
}

我遇到了问题：

=== RUN   TestExample1
    htmltopdf_test.go:12: 
                Error Trace:    htmltopdf_test.go:12
                Error:          Received unexpected error:
                                fork/exec /Users/rpantoja/Desktop: permission denied
                Test:           TestExample1
--- FAIL: TestExample1 (0.00s)
=== RUN   TestExample2
    htmltopdf_test.go:18: 
                Error Trace:    htmltopdf_test.go:18
                Error:          Received unexpected error:
                                fork/exec /Users/rpantoja/Desktop: permission denied
                Test:           TestExample2

这是我的htmltopdf.go文件的外观：

package htmltopdf

import (
    "bytes"
    "io/IoUtil"

    "github.com/SebastiaanKlippert/go-wkhtmltopdf"
)

const path = "/Users/rpantoja/Desktop"

func Example(file string,pdfFile string) error {
    html,err := IoUtil.ReadFile(file)
    if err != nil {
        return err
    }

    wkhtmltopdf.SetPath(path)

    pdfg,err := wkhtmltopdf.NewPDFGenerator()
    if err != nil {
        return err
    }
    page := wkhtmltopdf.NewPageReader(bytes.NewReader(html))
    page.NoBackground.Set(true)
    page.disableExternalLinks.Set(false)
    pdfg.AddPage(page)
    pdfg.Dpi.Set(350)
    pdfg.MarginBottom.Set(0)
    pdfg.MarginTop.Set(0)
    pdfg.MarginLeft.Set(0)
    pdfg.MarginRight.Set(0)

    err = pdfg.Create()
    if err != nil {
        return err
    }

    err = pdfg.WriteFile(pdfFile)
    if err != nil {
        return err
    }

    return nil
}

似乎我缺少什么，是否缺少任何配置，任何想法？
