Question

我让Selenium和Chrome完美运行，但自上周以来它已不再适用了。这就是我得到的：

Caused by: org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

现在我想知道为什么，因为我没有改变任何设置。它启动了safari浏览器，但是来自nightwatch的waitForElement不起作用。所以有人可以通过错误告诉我为什么我遇到这个问题？

Answer 1

我的解决方案很简单，我觉得特别愚蠢。不知怎的，我的/ etc / hosts文件被更改了（MAMP？我的错？）和

127.0.0.1 localhost

部分遗失了。因此机器无法将localhost用作127.0.0.1

希望有一天这会帮助一个可怜的人：/

Answer 2

运行nightwatch.js测试时也出现了同样的错误，我的问题也是由于/ etc / hosts文件输入错误造成的：

0.0.0.0 localhost

删除上述条目后，错误消失了。

Selenium 3.1.0 Standalone和chromedriver 2.27
