如何向chromedriver.exe授予权限？

Question

我在人脸识别项目中使用了chrome驱动程序，但在下面的第4行出现了错误。如何向chromedriver.exe授予权限？

代码：

data_path = '/content/drive/MyDrive/FaceRecognition/faces' 
onlyfiles = [f for f in listdir(data_path) if isfile(join(data_path,f))]
url='https://www.naver.com/' 
browser = webdriver.Chrome(r'/content/drive/MyDrive/FaceRecognition/chromedriver/chromedriver.exe')

======================================================================================================错误消息：

During handling of the above exception, another exception occurred:

     90             else:

Answer 1

此错误消息...

PermissionError: [Errno 13] Permission denied: '/content/'
.
WebDriverException: Message: '' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

解决方案

在传递密钥executable_path时，您需要传递WebDriver变量名称的绝对路径，即chromedriver，如下所示：

driver = webdriver.Chrome(executable_path='/content/chromedriver')
                          webdriver variant name ^^^chromedriver^^^ needs to be appended
