Not sure if this is an issue or some fault from my side, it was working in my local system(installed long back) but not working in digital ocean server. 我不确定这是问题还是某些故障,它在我的本地系统中工作(安装很久),但在Digital Ocean Server中却不工作。 Both are Ubuntu 14.
两者都是Ubuntu 14。
I followed instructions from this page - http://fedir.github.io/web/blog/2013/09/25/install-wkhtmltopdf-on-ubuntu/ 我按照此页面上的说明进行操作-http://fedir.github.io/web/blog/2013/09/25/install-wkhtmltopdf-on-ubuntu/
Note that I was able to generate pdfs using terminal commands but not using pdfkit. 请注意,我能够使用终端命令生成pdf,但无法使用pdfkit。
Please let me know if I missed anything. 如果我错过了任何事情,请告诉我。
