【问题描述】：

我正在尝试制作一个可用作 instagram.com 模块的 Python 程序。代码如下：

from selenium import webdriver
from getpass import getpass

user = input("Enter your username/email: ")
pwd = getpass(prompt="Enter your password: ")

driver = webdriver.Chrome()
driver.get("https://www.instagram.com/accounts/login/")

usr_box = driver.find_element_by_class_name("_2hvTZ.pexuQ.zyHYP")
usr_box.send_keys(user)

执行此操作后出现错误：

Traceback (most recent call last):
  File "C:\Users\***\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

    driver = webdriver.Chrome()

【问题讨论】：

那么 chromedriver 在你的路径上吗？

我运行了 .exe 但我不确定如何将它添加到我的路径中

您是否尝试搜索例如“Windows 将可执行文件添加到路径”?

【参考方案1】：

将 Chromedriver 可执行文件的路径添加到您的 Windows PATH 变量中，或者您可以在创建 WebDriver 对象时指定可执行文件的路径：

driver = webdriver.Chrome('/path/to/chromedriver')

例如

driver = webdriver.Chrome('/Users/username/Downloads/chromedriver.exe')
