错误：

^{pr2}$

Answer 1

错误来自于您如何调用Open Browser-您正在将位置传递给驱动程序exe，但它需要的是不同的内容-一个带有浏览器名称的字符串。E、 g.这：

Open Browser    https://www.gmail.com    ${chromedriver}

一定是这样的：

^{pr2}$

如果您想为webdriver（在您的例子中是chromedriver）自定义位置，自定义为不在用户的路径中，您有两个选项-在运行时将其添加到那里：

Append To Environment Variable      PATH    C:\\Users\\mahendra\\Downloads\\chromedriver_win32\\

（该关键字在OperatingSystem库中）

，或使用Create Webdriver关键字实例化驱动程序：

Create Webdriver     Chrome     executable_path=${chromedriver}
