我在运行Rspec时遇到问题：
我的RSpec测试与bundle exec rake spec正常运行，但bundle exec rspec spec错误的宝石错误。
我在使用Railsinstaller的Windows 7操作系统上使用Rails 4.1.0和Ruby 1.9.3p484 (2013-11-22) [i386-mingw32]。
C:\RailsInstaller\Ruby1.9.3\myapp>bundle exec rspec spec
bundler: command not found: rspec
Install missing gem executables with `bundle install`
当我尝试使用像bundle exec rspec spec/models/project_spec.rb这样的命令来缩小规范测试时，我的所有测试都会运行，从而大大减慢了我的测试驱动开发速度。我已经在多个Rails项目中使用spec测试重复了这个问题，包括来自我从Github克隆的测试的项目。从Rails 4.0.1降级到Rails 4.0.0并没有解决问题。我的Bundler版本是1.6.2。
我在C：\ RailsInstaller \ Ruby1.9.3 \ lib \ ruby \ gems \ 1.9.1 \ gems中安装了rspec-rails gem，安装似乎工作正常：

请你试试这个。
bundle exec "rspec spec"
或
bundle exec rspec
答案 1 :(得分：0)
您需要使用或正在使用的ruby版本不是rspec正在使用的版本。 rspec是/usr/bin/rspec的路径，其第一行令人遗憾
#!/usr/bin/ruby
将您的平台与任何版本/usr/bin/ruby联系起来。通过更改文件或在路径中先前创建新的rspec来解决此问题：
#!/usr/bin/env ruby
（在某些系统上，它必须是#!/bin/env ruby）。
要将rspec与用户本地宝石一起使用（例如，在$HOME/.gem中），必须指定$GEM_PATH。基本上rspec不尊重您的$HOME/.gemrc文件。
也许bundle exec解决了上述问题，但对我来说它创造了更多。
