如何修复错误消息：“chromedriver.exe”可执行文件可能有错误的权限[重复]

Question

我正在安装 selenium 的 webdriver。但是我收到以下错误：

PermissionError                           Traceback (most recent call last)

   1345                 raise child_exception_type(err_msg)

PermissionError: [Errno 13] Permission denied: '/usr/bin/chromedriver.exe'

During handling of the above exception, another exception occurred:

我已经下载了chromedriver.exe并将其添加到/usr/bin，代码行如下：!sudo mv /usr/local/bin/chromedriver.exe /usr/bin

你不能解决我的代码错误吗？ 提前致谢！

这可能是因为平台和 chromedriver 格式不匹配。例如 windows 需要 chromedriver.exe，而 linux 和 mac 有不同的格式。如果您不想通过包管理器安装，只需从网站下载 chromedriver。 https://sites.google.com/a/chromium.org/chromedriver/downloads

如果仍然出现错误，则转到 /usr/bin 目录，您需要运行 chmod a+x chromedriver 之类的东西来将其标记为可执行。
