Question

我们使用Gitlab CI（Runner）来测试我们的Rails应用程序，但是，当我们使用RSpec + Capybara +：chrome_headless时，它只会显示以下错误消息：

$ bundle exec rspec spec/features
Puma starting in single mode...

但是，我可以在同一服务器上运行irb + Capybara + Selenium + chromedriver，而不会出现错误：

还有一件事...当我尝试在同一台服务器上手动运行测试时，出现了其他错误Could not find nokogiri-1.8.4（但是GitLab CI bundle install没问题，关于nokogiri的错误）：

我还尝试将chromedriver降级到2.39，但仍然是相同的错误。

请帮助，我用Google搜索了很多，但是没有运气。谢谢。

顺便说一句，我没有使用gem chromedriver-helper，并且在我的开发人员上进行的本地测试没有错误。

更新：

更改为Firefox后，它仍然显示错误：
