各位好,我用python 寫了一個可以下載youtube 影片的功能
但執行下出現了一些錯誤,但找網路上也好像找不太到解法
以下是我的程式碼
from pytube import YouTube
link = "https://www.youtube.com/watch?v=X8WkCAAD2gI"
yt = YouTube(link)
stream = yt.streams.first()
stream.download('./youtube')
然後附上我的環境,我是以vituralenv下的方式執行的
python 3.6.4
pip pip 18.0 from {環境資料夾}/lib/python3.6/site-packages/pip (python 3.6)
我的module 如下(我也很確定有安裝pytube)(以下僅列出我覺得重要的modules)
Package Version
certifi 2018.8.24
pip 18.0
pytube 9.2.3
requests 2.19.1
setuptools 40.2.0
urllib3 1.23
wheel 0.31.1
執行後出現的錯誤如下(看來是ssl 的問題,但我該如何解?)

哈 錯誤有點多,有點意外,我也只是按照readme 貼上去執行的而已啊? 好奇是我哪裡寫錯了還是什麼東西沒有安裝嗎?
用pip修改一下 應該是版本不同造成的錯誤
pip uninstall pytube
pip install -v pytube==6.4.2
即可正常執行 pytube 程式。
