我的 Python Selenium 代码不适用于选项

Question

我在 spyder 3.8 中使用 selenium 代码和 anaconda。问题是，当我不向驱动程序添加任何选项时，它会完美运行，它会转到 url 并单击它必须单击的内容，但由于某种原因，当我添加选项时，它只会打开浏览器，但不会转到 url 并且无法继续代码。这很奇怪，因为我在其他 2 台装有 spyder 3.7 和旧版本的电脑上运行尝试了这段代码，并且它与选项完美运行。

如果有人能帮助我，我将不胜感激，感谢您的关注！

Answer 1

您的选项中有问题的条目是：

"plugins.always_open_pdf_externally": True

我建议改用这个：

"plugins.plugins_list": [{"enabled": False, "name": "Chrome PDF Viewer"}]

它做同样的事情；允许下载 pdf 文件而不是显示它们。
