主题说明了一切。使用OSX Yosemite，尝试更新Webdriver，chromedriver和PhantomJS，得到此错误：

任何帮助将不胜感激！
谢谢詹姆斯
更新：我添加了上面的更多错误消息。
Error: spawn EACCES错误意味着该文件不可执行。 我假设您使用的是基于文件路径的Mac，因此这样的事情应该可以解决您的问题：
cd /Users/jbender/Documents/Github/PTest/
chmod -R +x *
当然，这可能不是您想要做的，因为这会使您的所有文件都可执行。它可能是node_modules目录中需要可执行文件的文件之一。没有更多信息，我无法告诉你是哪一个。你大概可以自己弄清楚。
呃！好的，事实证明我的 Java 安装以某种方式损坏了。当我去启动WebStorm时，我注意到了这一点，它抱怨了。重新安装，现在很好。感谢您的帮助！
