我正在尝试在CI中的docker中使用 capybara 和幻影运行rspec测试。我已经安装了google-chrome-stable，但收到疯狂的错误。
如果我只运行rspec，它将启动puma执行测试，然后手动处理10分钟以上。
疯狂的是，如果我添加rspec过滤器或排除模式，我的所有测试规范都会失败，并出现以下错误。
我正在使用最新版本的所有版本(rspec-rails， capybara ，幻影)运行Rails 6.0.0rc2
如果我在CI上运行测试而没有完整的外观测试，则一切正常。
我用谷歌搜索了这个Could not load native IDN implementation.并试图清除我的CI worker 的缓存，但这无济于事。
我使用此docker文件构建镜像

事情是，我只有5个测试示例，所以看来失败的测试来自内部
有什么办法找出为什么我会得到所有这些疯狂的错误吗？
最佳答案
在为幻影驱动程序添加browser_options后解决了问题。如果没有--no-sandbox选项，Chrome将无法以root用户身份运行。要添加它，只需像这样初始化驱动程序
Capybara.register_driver :apparition do |app|
opts = {
headless: true,
browser_options: [
:no_sandbox,
{ disable_features: 'VizDisplayCompositor' },
:disable_gpu
]
}
Capybara::Apparition::Driver.new(app, opts)
end
