无法生成 WKHTMLTOPDF PDF

如何解决无法生成 WKHTMLTOPDF PDF

我的 rails 应用程序在许多方面都运行良好，但是当我尝试在生产服务器上生成 pdf 时，出现以下错误。在我的本地计算机上，它工作正常。我该怎么办？。

 Command Error: /home/deploy/.rbenv/versions/2.7.2/lib/ruby/2.7.0/bundler/deFinition.rb:495:in `validate_ruby!': Your Ruby version is 2.7.0,but your Gemfile specified 2.7.2 (Bundler::RubyVersionMismatch)

Note that am using ruby 2.7.2 and I dont have ruby 2.7.0

解决方法

尝试删除应用根目录中的“bundle”文件夹（在生产服务器上），然后运行“bundle”或“bundle install”。前段时间为我解决了这个问题。
