Chlenmedriver for selenium PermissionError：[Errno 1]操作不允许在Mac OSx上出错

Question

我有以下python代码

import time
from selenium import webdriver

driver = webdriver.Chrome('/Users/xxxx/Downloads/chromedriver')  
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

当我执行这个python脚本时，我得到异常：

Traceback (most recent call last):
  File "/var/folders/0m/p0pyygms6g9_bqlfb9bmg0w80000gn/T/PythonRunner/dummy.py", line 4, in <module>

    raise child_exception_type(errno_num, err_msg, err_filename)
PermissionError: [Errno 1] Operation not permitted: '/Users/xxxx/Downloads/chromedriver'

我已尝试将chromedriver Linux可执行文件的更改权限更改为777并重新安装selenium但出现了相同的错误

我在解决此问题时需要帮助。请告诉我。

Answer 1

错误说明如下：

driver = webdriver.Chrome('/Users/xxxx/Downloads/chromedriver')  # Optional argument, if not specified will search path.

您必须通过键值对提及chromedriver二进制的绝对路径，如下所示：

from selenium import webdriver

driver = webdriver.Chrome(executable_path='/Users/xxxx/Downloads/chromedriver')  
driver.get('http://www.google.com');

Answer 2

您可以尝试将webdriver移动到/ usr / local / bin

import time
from selenium import webdriver

driver = webdriver.Chrome()  
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()
