在Selenium/Python中获取错误 - chromedriver可执行文件需要在PATH中

Question

首先，我知道这个问题在这里被问了很多。只是明确表示我已经阅读了大多数接受的答案并正确遵循了所有步骤，仍然收到有关问题中的此错误。 这是我下面的脚本以及所有其他信息

[ 我正在使用带有 chromedriver 的硒，试图在运行 ubuntu 20 的无头模式下将其与 chromium 浏览器一起使用 ]

猫 test.py

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.binary_location = '/usr/bin/chromium-browser'
driver = webdriver.Chrome(options=options, executable_path='/usr/local/bin/chromedriver')
driver.get("https://www.google.com")
print(driver.title)
print ("Headless Chrome Initialized")
driver.quit()

蟒蛇3 test.py

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

我遵循了哪些步骤

sudo apt install chromium-browser
python3 -m pip install selenium
wget https://chromedriver.storage.googleapis.com/83.0.4103.39/chromedriver_linux64.zip
unzip chromedriver*
chmod +x chromedriver
sudo mv chromedriver /usr/local/bin/
sudo chown root:root /usr/local/bin/chromedriver
sudo chmod 0755 /usr/local/bin/chromedriver

一起验证一切

apt -qq list chromium-browser && 
which chromedriver &&

Description:    Ubuntu 20.04 LTS

/usr/local/bin/chromedriver
/usr/bin/chromium-browser
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

一切看起来都很好，有人可以建议我做错了什么吗？

我在本地运行的 Ubuntu20 是我在安卓设备上使用的 Ubuntu Proot

Answer 1

经过几天的弄清楚，我终于能够修复这个错误。

所以正如我所提到的，我在Android设备上运行Proot Ubuntu 20。现在这里的 linux 内核架构是 aarch64 似乎不受官方 chrome 网络驱动程序的支持 - https://chromedriver.chromium.org

要解决此问题，只需下载为arm64变体编译的chromedriver。您可以随时从这里获得最新的 - https://github.com/electron/electron/releases

简而言之，其他一切都很完美，只需要用 - https://github.com/electron/electron/releases/download/v8.3.4/chromedriver-v8.3.4-linux-arm64.zip 替换 wget 链接

PS/也许如果错误是这样的 - 不支持 linux 内核架构 ，修复它会容易得多，但没关系。

Answer 2

1. chromedriver 我总是传递给构造函数
2. 如果找不到，则会发生 PATH 错误(请参阅下面的示例，我故意传递不正确的参数(
3. 此驱动程序不适用于铬，仅适用于铬。 因此，有理由将驱动程序与/usr/bin目录分开

import time, os, datetime, json, requests, re, subprocess

except selenium.common.exceptions.WebDriverException as e:

输出：
