【问题描述】：

我是 Rails 新手，我想使用 Mac 运行 Rspec。

当我跑步时：

bundle exec rspec spec/00_hello_spec.rb

我收到以下回复：

请提供有关此问题的任何建议或说明。补充一点，我已经在文件系统的各个级别从根向上完成了此操作。我非常感谢任何帮助我摆脱困境的澄清。

【问题讨论】：

你跑rails generate rspec:install了吗？
文件spec/spec_helper.rb是否存在？该文件通常是自动生成的，但如果您可以轻松地手动添加它。
文件spec/00_hello_spec.rb 的第一行可能是require "spec_helper"，并且该文件不存在。这就是错误消息告诉您的内容。
> 我能够让它工作完成此操作的命令是什么？
这种评论——“哦，没关系，我想通了”——对于其他在搜索错误消息后发现这个问题的人来说毫无帮助。

标签： ruby rspec

【解决方案1】：

如果以后有人遇到此问题，请尝试查看您是否安装了多个版本的不同 rspec gem，如下所示：

gem list | grep rspec

如果您这样做了，请删除与您的 Gemfile.lock 中的内容不匹配的 gem 版本，如下所示：

gem uninstall <gem_name> <gem_version>

按照这些步骤我能够成功运行rspec spec！
