什么是适合我的Firefox版本的geckodriver？
我正在尝试使用Firefox在Amazon Linux上运行nodeJs（节点v 8.8.1）自动化testing。 由于亚马逊Linux的一些限制，最新版本的firefox taht实际上运行的是41.下面是我的Firefox和亚马逊版本…
[myuser@mymachine ~]$ firefox -v Mozilla Firefox 41.0 [myuser@mymachine ~]$ uname -a Linux ip-33-22-3-77 4.9.51-10.52.amzn1.x86_64 #1 SMP Fri Sep 29 01:16:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux 我的问题是，我使用什么版本的Geckodriver与此版本的Firefox兼容？ 有了最新版本，我们得到错误，试图产生一个Firefox窗口，没有在我们的path壁虎驱动程序，我们得到了错误

编辑：根据答案，我删除并重新安装了selenium2.53驱动程序…
npm uninstall selenium-webdriver npm install selenium-webdriver@2.53
但现在我得到一个新的错误…

由于firefox版本是41，所以使用selenium 2好，如果我们使用selenium 3意味着最新的，我们需要不支持这个旧版本的gecko。
我使用selenium2与Firefox的依赖http://selenium-release.storage.googleapis.com/index.html?path=2.53/与最新铬和IE驱动程序与最新的铬和IE浏览器工作。
我想，你得到这个错误，因为它是要求geckodriver.exe 。 Geckodriver最初被称为0.8.0之前的电线。 请在您的系统PATH上提供exe文件。
你可以使用selenium3（我认为是最好的select，因为它的最新），而不提供壁虎（早期的FF版本）通过设置此属性为false
System.setProperty("webdriver.firefox.marionette", "false");
或做
FirefoxOptions options = new FirefoxOptions() .setLegacy(true);
你可能不得不寻找相当于nodejs。
编辑： 这是js版本
let options = new firefox.Options().useGeckoDriver(false);
当你这样做，FF将使用其传统扩展，而不是壁虎
如这里所述

发现亚马逊Linux的正确版本Firefox 41是selenium-webdriver 2.50，不多不less（尝试2.48和2.53，并得到了这两个失败）。
