#1 楼 @sensi 执行过，BOOTSTRAP 很多 css 都无法显示，我是直接下载 bs 放在 assets 里面的，运行 rails s 是好的，运行 rails s -e production 就不行了，感觉一个 css 把布局都弄乱了

#1 楼 @king1990_cool 我安装用是 root deploy 用的也是 root 之前也觉得是角色问题，后来用 root 用户 restart ngnix 还是这样

没有 rails=-=

支持！新手过去学习

希望尽快更新后续章节

我是直接下载 git 上源码，现在执行了 bundle install --path vendor/bundle 查到的有关资料是这样的：

这样项目依赖的 gem 既不是安装在系统目录，也不是用户目录，而是当前目录的 vendor/bundle 文件夹内。这样安装的 gem 每个项目独立，要清除项目的时候只要把整个项目目录删除就好了。（注意设置 git 忽略这个目录）

部署环境同理，也是安装到 vendor/bundle 目录：

bundle install --deployment 所以，一般情况把 Bundler 装到系统目录就够了，应用依赖装到应用目录中。关于 Bundler 的用法这里不再展开，可以查看官方网站：http://bundler.io/ 。

我从 git 上把完成的版本的 user_pages.spec.rb 覆盖后再执行出现：

这个问题我之前也出现过。。。请问是什么原因？

%>_<%都是复制粘贴的。。。我再看看跟 pdf 里是不是有差。。。

我是新手。。现在不怎么清楚测试的意义。。之前写 php 都是直接看结果。。现在看 railstutotial 看到中间部分，感觉测试代码写了很多。。。如果我是想按照自己想法做一个应用，测试是不是必须的？

已购买指南 还有 tutorial 两本，测试的需要买么？

做的一手好广告

蛮喜欢这款的界面 -0- 能不能拖走？
