Question

尝试执行

from selenium import webdriver

browser=webdriver.Chrome()

browser.get('http://www.google.com')

但不执行并引发错误

在处理上述异常期间，发生了另一个异常：

    browser=webdriver.Chrome()

使用pip install正确安装的硒

请帮助！

Answer 1

这不起作用，因为您没有提供chrome驱动程序的路径。ngOnInit() { fromEvent(this.buttonRef.nativeElement, 'click') .pipe(switchMap(() => this.http.get('whatever page number')) .subscribe(console.log)); }不知道WebDriver路径在哪里。

chromedriver

例如：

driver = webdriver.Chrome("path of the chrome driver Chromedriver.exe")

Answer 2

您可以为此目的尝试使用Firefox：

首先从此处下载Geckodriver：https://github.com/mozilla/geckodriver/releases/tag/v0.24.0

from selenium import webdriver
fox = webdriver.Firefox(executable_path='/path/to/downloaded/gecko/driver')
fox.get("https://www.google.com")

可以用google chrome来完成：

您可以从此处下载chrome驱动程序：

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

无需设置PATH变量。

硒脚本不在python中运行
