ImageMagick，回形针，macOs塞拉利昂

我完全绝望。我一直试图安装ImageMagick窗体两天，我仍然有问题用Paperclip gem i Rails。我使用MacOS的塞拉利昂和我已经通过的MacPorts安装ImageMagick的ImageMagick，回形针，macOs塞拉利昂

sudo port install ImageMagick

我检查安装目录：

which identify

，并返回选择/ local/bin目录/识别

我已经改变使用development.rb：

Paperclip.options[:command_path] = "/opt/local/bin"

当我已经输入控制台

port info ImageMagick

我有这个

        variety of formats. You can crop, resize, rotate, sharpen,

        operations are available from the command line as well as 
        through C, Ch, C++, Java, Perl, PHP, Python, Ruby and

当我创建了一个 “处方” tehre是一个错误：

回形针::中的RecipesController＃错误创建出现错误处理215f68293f2d16f1f79bd2e366a45a9620160928-61978-d794或的缩略图

我的控制器厕所KS这样的：

class RecipesController < ApplicationController 
before_action :find_recipe, only: [:show, :edit, :update, :destroy] 
def index 
    @recipe = Recipe.all.order("created_at DESC") 
end 

def new 
    @recipe = Recipe.new 
end 

def show 
end 

def create 
    @recipe = Recipe.new(recipe_params) 
    if @recipe.save 
     redirect_to @recipe, notice: 'Succesfully created new recipe' 
    else 
     render 'new' 
    end 
end 

def edit 
end 

def update 
    if @recipe.update(recipe_params) 
     redirect_to @recipe 
    else 
     render 'edit' 
    end 
end 

def destroy 
    @recipe.destroy 
    redirect_to root_path, notice: "Succesfully deleted" 
end 

private 

def recipe_params 
    params.require(:recipe).permit(:title, :description, :image) 
end 

def find_recipe 
    @recipe = Recipe.find(params[:id]) 
end 
end

型号：

class Recipe < ApplicationRecord 
has_attached_file :image, styles: { medium: "400x400#>" } 
validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/ 
end

和形式：

= simple_form_for @recipe, html: { multipart: true } do |f| 
- if @recipe.errors.any? 
    #errors 
     %p 
      = @recipe.errors.count 
      Prevented this recipe froms saving 
     %ul 
      - @recipe.errors.full_messages.each do |msg| 
       %li= msg 
.panel-body 
    = f.input :title, input_html: { class: 'form-control' } 
    = f.input :description, input_html: { class: 'form-control' } 
    = f.input :image, input_html: { class: 'form-control' } 

= f.button :submit, class: "btn btn-primary"

当我创建的配方不选择它工作正常的图像，但是当我选择一个我有错误。

我不知道问题在哪里。我应该更新MagickInfo还是...？

这可能是帮助卸载XZ

brew uninstall xz

这说明我多么愚蠢我。问题出在AdBlock在Chrome中运行。它也阻止了Rails中的图像。
