Chromedriver 意外退出。状态代码为：在 Flask venv 上运行 selenium 时出现 127 错误

Question

我正在构建我的第一个 Flask 应用程序，但在集成 selenium 时遇到问题。该应用程序从 html 文本字段获取输入，使用它通过 selenium 传递到搜索字段，然后运行一些代码。但是，在文本字段中输入内容并点击提交后，我收到以下错误：

An error occurred in get_lyrics: Message: Service /home/vsherr/.cache/selenium/chromedriver/linux64/120.0.6099.109/chromedriver unexpectedly exited. Status code was: 127

An error occurred: Message: Service /home/vsherr/.cache/selenium/chromedriver/linux64/120.0.6099.109/chromedriver unexpectedly exited. Status code was: 127

During handling of the above exception, another exception occurred:

我尝试升级selenium并安装许多软件包，包括：

pip install -U selenium

pip install --upgrade chromedriver-autoinstaller

sudo apt-get install -y chromium-browser

可能是什么原因造成的？

编辑：我已经缩小了范围，但仍然没有解决问题。这与 chromedriver 在 Ubuntu 中无法工作有关。以前的解决方案涉及编辑文件路径以访问 chromedriver。然而，这个解决方案已经过时了，因为 chromedriver 不再需要文件路径。

Answer 1

我修好了！与损坏的依赖/安装有关。使用 pip install dependency 解决了第一个问题。然后我使用

sudo apt --fix-broken install

来修复所有这些安装。现在完美运行。
