我有一个rails应用程序并在VPS上运行，Ruby，Rails和RSpec的安装步骤在我的笔记本电脑和VPS上是相同的（后面是same instruction）。
但是当我想要的时候要在VPS上使用RSpec测试应用程序，它会出现uninitialized constant错误（类似this）。项目的确切克隆运行完美，笔记本电脑没有任何错误！
虽然测试在我的笔记本电脑上执行没有任何问题，但我尝试在网上存在解决方案，但对我没有帮助 - 甚至我在服务器上重新安装了Ruby，Rails和RSpec！
我需要提一下，该应用程序通过网络（应用程序是一个网站）在服务器上运行完美，没有任何问题。这肯定是RSpec问题;不是Ruby或Rails。
确切的错误输出如下：

RSpec有什么问题？
RSpec没有任何问题。
我该如何解决这个问题？
您不应该在生产中运行测试套件。工具集中的不同工具有许多步骤可以阻止您这样做（如隐式环境变量设置。）如果您仍然肯定要远程运行测试（您不应该这样做），那么应该使用明确的环境设置可能有帮助：
RAILS_ENV=test bundle install
RAILS_ENV=test bundle exec rspec
