PDF 生成适用于本地主机，但不适用于 Web 主机

Question

我正在使用 Rotativa 生成我的 Razor View 的 pdf。它在我的本地机器上运行良好，但是当我将网站发布到网络主机并尝试生成 pdf 时，出现以下错误：

控制器动作方法

 //Generate and output the View pdf file
        public ActionResult PDFCatalogue(int id)
        {
            var productList = db.ProductImages.Include("Products")
                          .Select(m => new ProductDisplayViewModel
                          {
                              ProductId = m.Id,
                              Name = m.Products.Name,
                              ImageUrl = m.URL,
                              Thumbnail = m.URL.Replace(".jpg", "-thumb.jpg"),
                              CategoryId = m.Products.CategoryId,
                              CategoryName = m.Products.Category.CategoryName,
                              Sizes=m.Products.Sizes
                          }).Where(i => i.CategoryId == id).OrderByDescending(m => m.ProductId).ToList();

            TempData["CategoryName"] = db.Category.Where(m => m.Id == id).Select(k => k.CategoryName).SingleOrDefault();
            if (productList == null)
            {
                return HttpNotFound();
            }

            return View("~/Views/Catalogue/PDFCatalogue.cshtml", productList);
            //return new RazorPDF.PdfResult(productList, "~/Views/Catalogue/PDFCatalogue.cshtml");
            //return new MvcRazorToPdf.PdfActionResult("~/Views/Catalogue/PDFCatalogue.cshtml", productList);
        }

        public ActionResult GeneratePDF(int id=0)
        {
            return new Rotativa.ActionAsPdf("PDFCatalogue", new { id = id });
        }

P.S: Rotativa 在应用程序的根目录中创建一个目录Rotativa，其中放置wkhtmltopdf.exe 我还设置了Rotativa 目录的权限，以完全控制应用程序池用户

我遇到了一个类似的问题，发现 this 帖子在页面下方显示将生产服务器上的 .exe 文件替换为下面链接中的文件。这解决了我的问题
