在 Windows 上，我正在尝试更新 ChromeDriver 以利用 Chrome 的新 headless 选项。不过，更新完成后，ChromeDriver 就会恢复到之前的版本。
在下面命令提示符的控制台日志中，您可以看到我下载的是2.33版本，但最后我得到的版本是2.27。我至少需要 2.29 才能使用 headless Chrome。
C:\WINDOWS\system32>npm uninstall chromedriver

我做错了什么/遗漏了什么？
最佳答案
很可能您的路径中有另一个 chromedriver。您可以在cmd提示符下使用PATH命令来检查路径中是否有另一个chromedriver。如果您有另一个 chromedriver，您可以通过下载所需版本来手动更新它，也可以将 npm 安装的版本添加到您的 PATH(位于以下位置):
C:\WINDOWS\system32\node_modules\chromedriver\lib\chromedriver
此外，您可以在上述位置检查 chromedriver 的版本
C:\WINDOWS\system32>C:\WINDOWS\system32\node_modules\chromedriver\lib\chromedriver --version
