无法在AWS Cloud9中的Python中使用硒运行chromedriver

Question

在将seelenium，chr​​ome和chromedriver安装到AWS cloud9之后，我尝试执行chromedriver。 但是发生了PATH错误。

我检查了chromedriver路径是否正确。 而且我不知道为什么会发生此错误。

aws:~/environment/seleniumTest $ ll /home/ec2-user/environment/seleniumTest/chromedriver
-rwxr-xr-x 1 ec2-user ec2-user 8496784 Sep 13  2018 /home/ec2-user/environment/seleniumTest/chromedriver

是否有解决此问题的解决方案？

我的步骤如下

1.安装selenium pip安装selenium -t ./

2.安装chrome curl https://intoli.com/install-google-chrome.sh | 重击

3.下载chromedriver curl -SL https://chromedriver.storage.googleapis.com/2.42/chromedriver_linux64.zip > chromedriver.zip解压缩chromedriver.zip

4，执行以下Python代码

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    options = Options()
    options.add_argument('--headless')

    driver = webdriver.Chrome('/home/ec2-use/environment/seleniumTest/chromedriver', chrome_options=options)

    return(0)

我收到“'chromedriver'可执行文件需要在PATH中”错误。

Answer 1

我不确定您是否为Chromedriver指定了正确的execute_path，我认为以下方法应该有效：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    options = Options()
    options.add_argument('--headless')

    driver = webdriver.Chrome(executable_path='/home/ec2-user/environment/seleniumTest/chromedriver', chrome_options=options)

    return(0)
