MOSS-TTS-Nano's compatibility with Windows file path length limitations and environment variable configuration.

Technical Positioning
Ensuring robust and user-friendly deployment on Windows operating systems, particularly regarding file system interactions and environment variable management.
SaaS Insight & Market Implications
This issue exposes a fundamental Windows compatibility problem for MOSS-TTS-Nano, specifically related to maximum file path length limitations. Despite attempts to mitigate this with environment variables for download directories, the problem persists, indicating a deeper architectural dependency or a misunderstanding of Windows file system behavior. For a model aiming for "simple enough for local demos" and "lightweight product integration," such persistent installation blockers on a dominant desktop OS like Windows are critical. This creates significant developer friction, increasing support overhead and deterring adoption. The market implication is a reduced addressable market on Windows platforms, as users encounter frustrating setup failures. Robust cross-platform compatibility, especially concerning file system nuances, is non-negotiable for broad developer tool adoption.

之前也是这个错误。。。路径超过最大字符，改了环境变量，下载到了对应的目录里面，貌似还是这个报错。。

如果设置了这个路径，是不是要改回环境变量？
