我无法让rails插件wicked_pdf工作
[英]I can't get rails plugin wicked_pdf to work
问题描述
I wanted to create PDFs for my rails application using wkhtml2pdf and wicked_pdf. 
我想使用wkhtml2pdf和wicked_pdf为我的rails应用程序创建PDF。
I downloaded and extracted wkhtml2pdf beta 4 and placed it in /usr/local/bin/wkhtml2pdf 我下载并提取了wkhtml2pdf beta 4并将其放在/ usr / local / bin / wkhtml2pdf中
I tried running it on a web site and it gave a nice result. 我尝试在网站上运行它，结果很好。
In my rails application (2.3.4) I installed wicked_pdf: 在我的rails应用程序（2.3.4）中，我安装了wicked_pdf：
script/plugin install git://github.com/mileszs/wicked_pdf.git
script/generate wicked_pdf
Everything seemed to be ok. 一切似乎都没问题。 inside script/console I run the following - (with the following output) 在脚本/控制台内我运行以下 - （使用以下输出）
wp = WickedPdf.new
=># WickedPdf:0xb62f2c70 @exe_path="/usr/local/bin/wkhtmltopdf" =>＃WickedPdf：0xb62f2c70 @exe_path =“/ usr / local / bin / wkhtmltopdf”
HTML_DOCUMENT = "<html><body>Hello World</body></html>"
=> " <html><body>Hello World</body></html>" >“ <html><body>Hello World</body></html>"
pdf = wp.pdf_from_string HTML_DOCUMENT
=> "/usr/local/bin/wkhtmltopdf - - -q" >> / usr / local / bin / wkhtmltopdf - - -q“
=> "\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n" =>“\\ n \\ n \\ n \\ n \\ n \\ n \\ n \\ n \\ n \\ n”
of course this isn't good. 当然这不好。 According to the test the result of my last command should start with "%pdf-1.4" 根据测试，我的上一个命令的结果应该以“％pdf-1.4”开头
Any idea what I can do? 知道我能做什么吗？

Having the same problem. 有同样的问题。 Removed the -q option from the wicked_pdf.rb file on line 19 and then was able to get the proper string on the console. 从第19行的wicked_pdf.rb文件中删除了-q选项，然后能够在控制台上获取正确的字符串。
=> "%PDF-1.4\n1 0 obj\n<<\n/Title ...
This also seems to have solved other problems. 这似乎也解决了其他问题。 The PDF still didn't render correctly when using it from the web site - embedded font issue - on to the next issue now. 从网站（嵌入式字体问题）使用PDF到现在的下一个问题时，PDF仍无法正确呈现。
Hopefully this will work for you. 希望这对你有用。
