部署Flask应用时Azure认知服务依赖DLL文件存在却提示找不到的问题求助

我有一个用Flask开发的应用，在本地机器上运行完全正常，现在我想把它部署到服务器上让其他人可以访问。我已经安装了所有需要的包，并且确认了所有包的版本都和本地环境一致。

看起来一切都没问题，但当我尝试运行应用时，抛出了如下错误：

C:\Users\Sparapan.F\Desktop\Scripts\Trascrittore\Tutto\trasc_env\Lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

one of its dependencies). Try using the full path with constructor syntax.

奇怪的是，错误提示中说找不到的那个DLL文件，实际上确实存在于指定的文件夹里，我现在不知道该怎么办了。

我已经尝试过以下方法：

• 卸载并重新安装Azure认知服务包
• 检查Python和系统版本（都是64位）
• 重启系统
