python - 错误“chromedriver”可执行文件需要在 PATH 中

问题描述

selenium.common.exceptions.WebDriverException: Message: '' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home当我尝试运行此代码时会出现此问题。我已经从链接下载了文件并将其解压缩到我的下载文件夹，如下所示： C:\Users\Alexandr\Downloads\chromedriver_win32 。然后我将可执行二进制文件 (C:\Users\michael\Downloads\chromedriver_win32) 的路径放入环境变量“Path”中。

我在 StackOverflow 上找到了相同的线程chromedriver，他们说我应该输入cmd 并得到类似的东西tarting ChromeDriver 2.15.322448，就我而言，我得到"chromedriver" is not inner or outer command了（这是我的母语的翻译）。在这种情况下我该怎么办

from selenium import webdriver
from time import sleep

class InstaBot:

    def __init__(self, username, password):
        self.driver = webdriver.Chrome()
        self.driver.get('https://www.instagram.com/?hl=ru')
        sleep(2)
        self.driver.find_element_by_xpath("//input[@name=\"username\"]") \
            .send_keys(username)
        self.driver.find_element_by_xpath("//input[@name=\"password\"]") \
            .send_keys(password)
        self.driver.find_element_by_xpath('//button[@type="submit"]') \
            .click()
        sleep(4)
        self.driver.find_element_by_xpath('//button[contains(text()."Не сейчас")]').click()


InstaBot('_max_leva_', here is my password)

这是错误代码：

During handling of the above exception, another exception occurred:

Process finished with exit code 1

环境变量：

%PATH%:C:\Users\Alexandr\Downloads\chromedriver_win32

标签： pythonseleniumselenium-webdriver

解决方案

在 中self.driver = webdriver.Chrome()，将可执行文件的路径作为括号中的参数传递。

例如：

self.driver = webdriver.Chrome('C:/user/Downloads/chromedriver.exe')
