Selenium是瀏覽器功能自動化測試工具，在終端界面下也能運行，所以可作爲爬蟲的 js 引擎。

關於 *.deb 的安裝，有三種辦法
1. dpkg -i [包名] ， 容易出現依賴不存在導致安裝失敗。因此先試錯一次，然後用apt install -f 去修復依賴
dpkg -i [包名]
apt install -f
dpkg -i [包名]
2. gdebi [包名]， 自動安裝依賴，但需要先安裝 gdebi
apt install gdebi
gdebi [包名]
3. apt install [包名]， 僅支持 ubuntu16.04 及之後版本， 需要注意的是即使在當前路徑包名前依然要加上路徑 ./
apt install [包名]
