For a temporary fix, This installs tha master version. Run it through the command-line where URL is the URL of the video you want. See yt-dlp --help for all options. It should just work without errors. If you're using it as a module, 在.py檔中以module引入 ``` import yt_dlp as youtube_dl ``` - [Error: Unable to extract uploader id - Youtube, Discord.py](https://stackoverflow.com/questions/75495800/error-unable-to-extract-uploader-id-youtube-discord-py) #### 更改`pafy`內的`backend_youtube_dl.py`import youtube_dl的程式碼 檔案位置在 `/home/user/.local/lib/python3.8/site-packages/pafy/backend_youtube_dl.py`中 可用vim指令進去修改 ```python=13 import yt_dlp as youtube_dl ``` - 修正yt_dl引發的`pafy/backend_youtube_dl.py`KeyError: 錯誤訊息: ``` File "/home/yunghui/.local/lib/python3.8/site-packages/pafy/backend_youtube_dl.py", line 54, in _fetch_basic self._dislikes = self._ydl_info['dislike_count'] ``` 在 `class YtdlPafy(BasePafy):`內的 ```python=54 # self._dislikes = self._ydl_info['dislike_count'] # fix ```
