python-3.x - 如何在 AWS Cloud9 中安装 chromedriver？

Question

环境

aws ec2

ec2-user:~ $ which python
alias python='python36'
        /usr/bin/python36

ec2-user:~ $ pip install chromedriver
Requirement already satisfied: chromedriver in ./.local/lib/python3.6/site-packages (2.24.1)

ec2-user:/usr/local/bin $ ls
chromedriver

问题

如何继续 chromeDriver.py 并获得想要的结果？

ec2-user:~/environment $ wget https://chromedriver.storage.googleapis.com/78.0.3904.70/chromedriver_linux64.zip

chromeDriver.py

from time import sleep
from selenium import webdriver

browser = webdriver.Chrome('/usr/local/bin/chromedriver')

browser.get("https://www.google.com")

browser.save_screenshot("screen.png")

sleep(5)

browser.close()

这是一个结果。

ec2-user:~/environment $ python3 chromeDriver.py

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

从路径 "$HOME:/.local/lib/python3.6/site-packages" 读取 selenium 是否正确？
