在rails中设置wkhtmltopdf路径

Question

我尝试使用wicked_pdf时遇到此错误:

irb: No such file or directory - which wkhtmltopdf
NoMethodError: You have a nil object when you didn't expect it!
The error occurred while evaluating nil.chomp
        from C:/Ruby187/lib/ruby/gems/1.8/gems/wicked_pdf-0.7.2/lib/wicked_pdf.r
b:19:in `initialize'
        from (irb):2:in `new'
        from (irb):2
        from :0

我认为应该配置wkhtmltopdf的路径.但是怎么样？

Answer 1

提供类似的

:wkhtmltopdf => '/usr/local/bin/wkhtmltopdf', # path to binary

与您的渲染调用,并确保wkhtmltopdf二进制文件驻留在该路径.(你可以从谷歌代码获得wkhtmltopdf ,以防你还没有安装它)
