導軌生產：捆綁鎖定爲耙

Question

我剛剛添加了導出到PDF使用wicked_pdf寶石我的應用程序。它的工作原理我的開發機上很好，但它不斷拋出下面的錯誤在生產服務器上：

I, [2016-12-01T03:40:46.110058 #2857] INFO -- : Rendered reports/summary_of_reports.pdf.erb within layouts/pdf.html (24.3ms)

): 
    app/controllers/reports_controller.rb:19:in `block (2 levels) in summary_of_reports' 
    app/controllers/reports_controller.rb:15:in `summary_of_reports' 

的一件事情是，我已經嘗試使用Rails的控制檯產生在生產服務器上的樣品PDF和它的作品，所以我很困惑，爲什麼這不起作用。

#view 
<%= link_to icon("file-pdf-o") + " Export as PDF", request.parameters.merge({format: :pdf}), target: "_blank" %> 

#controller 
def summary_of_reports 
    if params[:at].present? 
    @account_type = AccountType.find_by_id(params[:at]) 
    @accounts_total = Account.where(account_type: params[:at]).joins(:user).order('users.last_name') 
    @accounts = Account.where(account_type: params[:at]).joins(:user).order('users.last_name').paginate(page: params[:page], per_page: 30) 
    end 

    respond_to do |format| 
    format.html 
    format.csv { send_data Account.to_csv(@accounts_total), filename: "summary_of_reports_#{Time.now.strftime("%^b-%d-%Y-%H-%M")}.csv" } 
    format.pdf do 
     render pdf: "summary_of_reports_#{Time.now.strftime("%^b-%d-%Y-%H-%M")}", 
     template: "reports/summary_of_reports.pdf.erb", 
     locals: { 
      accounts: @accounts_total, 
      account_type: @account_type 
     } 
    end 
    end 
end 

我已經試過卸載並重新安裝rake和bundler寶石，以及運行bundle install和bundle update服務器端沒有用。

更新： 新增的Gemfile

更新2：嘗試卸載並重新安裝所有的寶石文件，仍然沒有好。

Answer 1

的wkhtmltopdf可執行文件看起來是一個rbenv binstub，其啓動時的捆綁式的環境，但可能有依賴關係rake。

嘗試增加

gem 'rake', '11.3.0' 

您Gemfile。

如果還是不行，請嘗試創建一個config/initializers/wicked_pdf.rb初始化與指定實際wkhtmltopdf二進制生產服務器（一個當你which wkhtmltopdf在命令行顯示出來）上的路徑。
