2 个解决方案

#1

I had the same problem. The solution was to add wkhtmltopdf-binary to the gem file and run bundle install.

我有同样的问题。解决方案是将wkhtmltopdf-binary添加到gem文件并运行bundle install。

gem "wicked_pdf"
gem "wkhtmltopdf-binary"

#2

I had wkhtmltopdf-binary already in gemfile, but as this was working on my local computer and not on server, I left this error for the server support team to care off.. they have checked the path to wkhtmltopdf, they tried to convert a simple html to pdf and it worked.. so they tried to run a bundle update command and after this the pdf converting worked fine on server too. I had a gem path changed and I guess this was the problem. I posted my solution in case someone else will have this problem too.

我已经在gemfile中使用了wkhtmltopdf-binary,但由于这是在我的本地计算机而不是在服务器上工作,我为服务器支持团队留下了这个错误来关心..他们已经检查了wkhtmltopdf的路径,他们试图转换一个简单的HTML到pdf,它工作..所以他们试图运行一个捆绑更新命令,在此之后,pdf转换在服务器上工作正常。我改变了宝石路径,我想这就是问题所在。我发布了我的解决方案,万一其他人也会遇到这个问题。
