mac 下使用 homebrew 安装 chrome
2023-12-26 software mac selenium homebrew chrome chromedriver 11 mins 11 图 3983 字
真是一波三折血泪史。
起因是要装 chromedriver，先看了官方的地址：https://chromedriver.chromium.org/downloads
怎么回事，不能装最新的，只能装114版本？
看样子 homebrew 的版本没有114的，还是用老一点的chrome版本，才能和官方稳定的 chromedriver 搭配干活。
brew info --cask google-chrome
brew install --cask google-chrome@114
完了，homebrew没有这个版本。网上乱七八糟的不放心，还是找比较像官方的：
- https://mrseawave.github.io/chromium-history-page/
- https://mrseawave.github.io/blogs/articles/2021/04/06/download-chromium-history-version/
下载下来发现用不了，无法运行。
算了，直接源码编译：https://chromium.googlesource.com/chromium/src/+refs
我用了114版本：https://chromium.googlesource.com/chromium/src/+/refs/tags/114.0.5735.346
放弃，怎么可能自己编译？！
又认真看了下，120和对应的chromedriver，这不是有吗？https://googlechromelabs.github.io/chrome-for-testing/
下载好了还是无法运行，心累了。
死马当活马医吧，用 homebrew 把 chrome 和 chromedriver 都装完：
试着跑一下 selenium-server 看：
没问题。用代码跑看也是OK的。写了个简单的动态加载另一个python文件的方法，适合debug。
