Answer 1

我有同样的问题.解决方案是添加wkhtmltopdf-binary到gem文件并运行bundle install.

gem "wicked_pdf"
gem "wkhtmltopdf-binary"

Answer 2

我wkhtmltopdf-binary已经进入gemfile,但由于这是在我的本地计算机而不是在服务器上工作,我留下这个错误让服务器支持团队关心..他们已经检查了wkhtmltopdf的路径,他们试图将简单的html转换为pdf它工作..所以他们试图运行一个bundle update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.
