邪恶的 PDF 在 OS X 上静默失败

Question

使用相同的代码和 gem 版本，它在 Ubuntu（14.04、64 位）中运行良好。目前我正在使用：

• wkhtmltopdf-binarygem v0.9.9.1
• wicked_pdfgem v0.10.2
• Rails 4.1.1
• Ruby 2.1.3
• OS X 10.10，64 位

当我尝试从 Rails 生成 PDF 时，我收到错误消息：wkhtmltopdf_darwin_386 quit unexpectedly。以下是完整的错误信息：

我之所以在标题中说静默，是因为当我检查服务器日志时，它运行良好。摘录如下：

"***************\"/Users/david/.rbenv/versions/2.1.3/bin/wkhtmltopdf\" -q  --footer-html \"file:////var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_footer_pdf20141118-1102-1uce4hg.html\"     --margin-bottom 13    \"file:////var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_pdf20141118-1102-1jrv3s8.html\" \"/var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_pdf_generated_file20141118-1102-qu51nc.pdf\" ***************"

运行which wkhtmltopdf 给了我/Users/david/.rbenv/shims/wkhtmltopdf.. 当我单独运行测试wkhtmltopdf（如wkhtmltopdf test1.html test1.pdf）时，它运行完美。

wkhtmltopdf_darwin_386 在基于 64 位的体系结构中是否可能无法正常工作？ （尽管我的 Ubuntu 也是基于 64 位的。）

感谢任何帮助。

Answer 1

你做过吗？ ：

创建/编辑文件：

config/initializers/wicked_pdf.rb

If your wkhtmltopdf executable is not on your webserver's path, you can configure it in an initializer:

WickedPdf.config = {
  :exe_path => '/Users/USER/*/wkhtmltopdf_darwin_386'
}
