推荐答案

即使安装谷歌Chrome，还有一些人失踪是由硒需要。这是chromedriver。 chromedriver可以在这个网站上下载 。目前，最新的版本是2.9。例如，如果一个人使用Windows，文件chromedriver_win32.zip需要被下载。

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 2.9. For instance, if one is using Windows, the file "chromedriver_win32.zip" needs to be downloaded.

当文件被下载，解压缩文件在里面，即chromedriver.exe。将你希望它是chromedriver.exe。我把它放在用户/文档/ R。

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".

在最后一个步骤中，需要添加其中chromedriver.exe位于到系统路径的文件夹。一种用于文件夹添加到系统路径的描述，可以发现的这里

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，我们可以重新开始的研究的并运行code。

Now, one can restart R and run the code.
