新手问题 rails tutorial 中第 7 章 sign up 测试出现问题
代码是直接从 github 下过来解压然后 bundle install 发现 rails s 后能正常运行 但是测试就是各种出现错误 bundle exec rspec spec/requests/user_pages_spec.rb -e "signup page" 执行这句的时候出现：
bundle exec rspec spec/requests/user_pages_spec.rb -e "signup page"

有语法错误
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？
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/ 。
