selenium.common.exceptions.WebDriverException：消息：会话未创建异常

Question

我正在尝试在我的 mac 版本 10.12.4 上使用 splinter，因为 selenium 是必需的，我正确安装了所有东西但是当我运行我的代码打开一个空白 chrome window 然后我一一收到这两个错误：

第一个错误：

Traceback (most recent call last):
  File "/Users/exepaul/Downloads/pythoncrawling/fix.py", line 14, in <module>

我搜索并找到了答案，建议更新您的 chrome 驱动程序，所以我安装了最新的 chrome 驱动程序并更新了 /etc/paths 中的路径，但我仍然是得到同样的错误，然后我试图理解这个错误，我想这可能是因为会话，所以我尝试在 python 中使用请求库创建会话：

import requests
MAX_RETRIES = 20


art="https://www.google.com"
session = requests.Session()
adapter = requests.adapters.HTTPAdapter(max_retries=MAX_RETRIES)
session.mount('https://', adapter)
session.mount('http://', adapter)
r = session.get(art)

但运气不好，我不知道如何解决这个错误，我的代码是：

from splinter import Browser
import pandas as pd



url="https://www.google.com"


browser = Browser('chrome')
browser.visit(url)

search_bar_xpath = '//*[@id="lst-ib"]'
search_bar = browser.find_by_xpath(search_bar_xpath)[0]
search_bar.fill("Tony_stark is Iron_Man")


search_button_xpath = '//*[@id="tsf"]/div[2]/div[3]/center/input[1]'
search_button = browser.find_by_xpath(search_button_xpath)[0]
search_button.click()


search_results_xpath = '//h3[@class="r"]/a'
search_results = browser.find_by_xpath(search_results_xpath)


scraped_data = []
for search_result in search_results:

    title = search_result.text.encode('utf8')
    link = search_result["href"]
    scraped_data.append((title, link))

df = pd.DataFrame(data=scraped_data, columns=["title", "link"])
df.to_csv("links.csv")

Answer 1

我认为你的 chromedriver 没有更新请从这里更新 link

https://sites.google.com/a/chromium.org/chromedriver/

我也没有在你的代码中看到这样的 chromedriver 路径

from selenium import webdriver 
driver=webdriver.Chrome('D:\Sankalp_Python\Python36\selenium\chromedriver.exe')

Answer 2

我解决了我的问题。由于很多人面临同样的问题，我想我会分享我的解决方案：

我正在通过 /etc/paths 更新 chromedriver 但是 pycharm 显示的是旧版本的 chrome driver 所以首先我有通过 :

卸载旧的 chromedriver

删除所有带有 brew uninstall --force chromedriver 的版本。
安装您可以下载的新版本here。

现在它完美运行

P.S ：我修复的另一个问题：我在访问 google 时没有使用安全连接，所以我必须使用 https://www.google.com instead of http://www.google.com
