我是新的编码，只是不明白这个错误代码的意思

Question

我最近才开始使用Python 3编写代码。我不知道如何表达我想问的问题，因为我不理解返回的这些错误的任何部分

    Traceback (most recent call last):
  File "C:\Users\Liam McAuley\AppData\Local\Programs\Python\Python38\lib\site-packages\selenium\webdriver\common\service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,
  File "C:\Users\Liam McAuley\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 854, in __init__

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

    driver = webdriver.Chrome('chromedriver.exe')

    raise WebDriverException(

有人能帮忙吗

Answer 1

系统找不到chromerdriver可执行文件。在使用Windows时，我建议使用可执行文件的完整路径定义：

driver = webdriver.Chrome(executable_path="C:\Users\Liam McAuley\path\to\actual\chromedriver.exe")

或者，您可以通过在命令提示符中键入此命令将chromedriver.exe添加到路径中（确保您以管理员身份运行！）

 setx CHROMEDRIVER=C:\Users\Liam McAuley\path\to\actual\chromedriver.exe
