mac 下使用 homebrew 安装 chrome

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：

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。
