推荐答案

我最近遇到了同样的问题.该问题是由完整的C驱动器引起的.显然chromedriver在C驱动器(或chrome二进制文件所在的驱动器)中需要一些空间来创建临时配置文件等.

I've recently had the same issue. The problem was caused by full C drive. Apparently chromedriver needs some space in C drive (or the drive where chrome binary file is located) to create temporary profile files and so on.

解决方案之一可能是将chrome安装移至其他驱动器.您可以在命令行窗口中使用 mklink命令.

One of the solutions could be to move chrome installation to some other drive. You could use mklink command in command line window.
