关于最近大量用户Whisper模型安装报错，FFMPEG安装网络报错，NLP模型下载失败报错的解决方法

如果你在Git源码安装最新版本时出现以下网络SSL相关报错：
equests.exceptions.ProxyError: HTTPSConnectionPool(host='github.com', port=443): Max retries exceeded with url: /BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl.zip (Caused by ProxyError('Unable to connect to proxy', FileNotFoundError(2, 'No such file or directory')))

ValueError: ❌ Failed to load NLP Spacy model: en_core_web_md

LocalEntryNotFoundError: Cannot find an appropriate cached snapshot folder for the specified revision on the local disk and outgoing traffic has been disabled. To enable repo look-ups and downloads online, pass 'local_files_only=False' as input
如果你使用源码安装，请在anaconda prompt powershell中执行conda activate videolingo后，执行python install.py命令前执行：
conda install certifi用于常态化虚拟环境网络代理
实测可以解决大部分国内使用VPN网络访问正常，但是虚拟环境下载网络的异常问题。

Start with install.py and reproduce the reported setup from an Anaconda PowerShell prompt after activating the videolingo environment. Check whether installing certifi before running python install.py prevents the reported FFMPEG, spaCy, and model-download errors, then document the confirmed steps and limitations.
