Bundler：无法加载命令：rspec。

Question

我是Rails的新手，我想在Mac上运行Rspec测试。

当我输入以下命令时：

bundle exec rspec spec/00_hello_spec.rb 

我得到了以下的回应：

bundler: failed to load command: rspec (/Users/OumouKaba/Downloads/test-first-ruby-master/vendor/bundle/ruby/2.4.0/bin/rspec)
LoadError: cannot load such file -- spec_helper

请协助提出任何建议或澄清此问题。另外，我已从根目录向上在文件系统的各个级别进行了此操作。非常感谢任何澄清以帮助我摆脱我的困境。

你运行了 rails generate rspec:install 吗？ - Sebastián Palma

文件 spec/spec_helper.rb 存在吗？通常情况下，该文件会自动生成，但是您也可以手动添加它。 - Tom Lord

你的文件 spec/00_hello_spec.rb 的第一行很可能是 require "spec_helper"，但是该文件不存在。这就是错误信息告诉你的内容。 - Tom Lord

我已经让它能够运行了。是哪个命令实现了这个功能？ - Andrew Farrell

这种评论——“哦，没关系，我搞定了”——对那些在搜索错误信息后发现这个问题的其他人来说，是极其没有帮助的。 - pjmorse

如果将来有人遇到此问题，请尝试查看是否安装了多个不同版本的rspec宝石，例如：

gem list | grep rspec

如果您这样做，请删除与您在Gemfile.lock中不匹配的宝石版本，如下所示：

gem uninstall <gem_name> <gem_version>

按照这些步骤后，我成功地运行了rspec spec！
