推荐答案

根据 ChromeDriver 的要求 :

ChromeDriver 由三部分组成.有浏览器本身，即 chrome ，Selenium项目提供的语言绑定(即驱动程序)和从Chromium项目下载的可执行文件，可作为之间的桥梁chrome 和驱动程序.此可执行文件称为 chromedriver ，我们通常将其称为服务器，以减少混乱.

The ChromeDriver consists of three separate pieces. There is the browser itself i.e. chrome, the language bindings provided by the Selenium project i.e. the driver and an executable downloaded from the Chromium project which acts as a bridge between chrome and the driver. This executable is called the chromedriver, we generally refer to it as the server to reduce confusion.

服务器希望您按照以下图片在每个系统的默认位置中安装Chrome:

The server expects you to have Chrome installed in the default location for each system as per the image below:

¹ 对于Linux系统，ChromeDriver希望/usr/bin/google-chrome是实际Chrome二进制文件的符号链接.如果您在非标准位置使用 Chrome 可执行文件，则必须覆盖Chrome二进制位置.，如下所示:

¹For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary. In case you are using a Chrome executable in a non-standard location you have to override the Chrome binary location. as follows:
