Python中未检测到的chromedriver启动错误

Question

对于某些网站来说，我需要使用未被检测到的色度驱动器来实现Selenium自动化。我已经在venv环境中安装了Selenium和chromedriver，并且运行以下命令在venv：python -m pip install undetected-chromedriver中安装未被检测到的chromedriver。我使用以下代码启动未被检测到的色驱动程序：

from selenium import webdriver
import undetected_chromedriver as uc
browser = uc.Chrome()
browser.get('any url here')

当我在venv中运行脚本时，我得到了错误消息。有人能帮上忙吗？

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

Answer 1

简单的解决办法是，您只需编写：

uc.Chrome(use_subprocess=True)

稍后再向我致谢;)

Answer 2

这是因为您没有将主方法封装在

if __name__ == "__main__":
    foo()
