【问题描述】：
在一个新的 Rails 项目中，我安装了带有 Ruby 1.9.3-p-194 的 Rails 3.2.11 我还安装了 spree 版本 1.3.1。
我在安装时采取的步骤：
rails new mystore
cd mystore
spree install -A
rails s
安装时一切正常，但是当我在http://localhost:3000/ 中打开它时，没有加载产品图像，但加载了 spree 徽标。
这是最后一张图片，但我对所有产品图片都一样：

我用identify -version检查了我的ImageMagic版本，我得到了：
Version: ImageMagick 6.8.2-2 2013-02-01 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2013 ImageMagick Studio LLC
Features: DPC OpenMP
Delegates: fontconfig freetype pango png ps x xml zlib
我还验证了 ImageMagick 安装是否正常工作：
/usr/local/bin/convert logo: logo.gif
谁能告诉我是我做错了什么还是另一个问题。
提前致谢。
【问题讨论】：
-
清除您的数据库 (
rake db:reset)，然后手动重新播种数据 (rake db:seed)，看看这是否会带来任何额外的错误或工作。我不知道为什么它不会立即显示图像。 -
rake db:reset表现良好，但是当我运行rake db:seed时会弹出此错误：loading fixture /home/usr/.rvm/gems/ruby-1.9.3-p194/gems/spree_core-1.3.1/db/default/spree/countries.yml rake aborted! SQLite3::ConstraintException: PRIMARY KEY must be unique: INSERT INTO "spree_countries" ("name", "iso3", "iso", "iso_name", "id", "numcode") VALUES ('Chad', 'TCD', 'TD', 'CHAD', 39, 148)
