推荐答案

即使安装了 Google Chrome，Selenium 仍然需要一些东西.这是chromedriver".chromedriver"可以在在这个网站上下载. 目前，最新版本是 2.25.例如，如果使用的是 Windows，则需要下载文件chromedriver_win32.zip".

Even though Google Chrome is installed, there is still something missing that is needed by Selenium. This is the "chromedriver". "chromedriver" can be downloaded on this website. Currently, the most recent version is 2.25. For instance, if one is using Windows, the file "chromedriver_win32.zip" needs to be downloaded.

下载文件后，解压其中的文件，即chromedriver.exe".将chromedriver.exe"放在您想要的位置.我把它放在用户/文档/R"中.

When the file is downloaded, extract the file in it, i.e. "chromedriver.exe". Place "chromedriver.exe" where you want it to be. I put it in "User/Documents/R".

最后一步，需要将chromedriver.exe"所在的文件夹添加到系统路径中.可以在 这里.

In the last step, you need to add the folder where "chromedriver.exe" is located to the system path. A description for adding a folder to the system path can be found here.

现在，可以重新启动R并运行代码.

Now, one can restart R and run the code.
