根据alexce的说明here安装了docker，scrapsjs和splash。
然后，运行docker run -p 8050:8050 scrapinghub/splash，我得到以下输出:

它卡在那里。我尝试根据指示here进行故障排除(重新安装docker，验证vm是否正在运行，重新生成证书，设置env)，但仍然没有执行任何操作。
My settings file和Spider
当在
meta= start_requests`中运行不带yield scrapy.Request' call within参数的蜘蛛时，蜘蛛运行良好(除了未捕获动态字段)，因此我不确定这是否与docker或splash有关。提前致谢。
最佳答案
当在Docker上运行Splash时，控制台首先确实会“卡在那里”。 Splash正在等待通过其端点之一的请求。
$ sudo docker run -p 8050:8050 scrapinghub/splash

要测试Splash是否运行正常，请在http://localhost:8050/上尝试其Web UI
您应该看到类似以下内容:
然后，您可以尝试输入一些URL，然后单击“渲染我!”。
