解決辦法

?

要解決UnicodeDecodeError，可以按照以下步驟操作：

1. 指定文件編碼：修改gradio庫中讀取文件時的編碼為UTF-8。

   • 找到component_meta.py文件，路徑通常位于Lib\site-packages\gradio\component_meta.py。

   • 在文件中找到pyi_file.read_text()，將其更改為pyi_file.read_text(encoding='utf-8')。

2. 設置環境變量（可選）：在運行腳本前設置PYTHONUTF8=1，強制使用UTF-8編碼。

   bash

1. set PYTHONUTF8=1 && python your_script.py

2. 更新庫版本：檢查gradio或fastrtc是否有新版本，可能已修復此問題。

示例修改步驟：

1. 打開文件：.venv\Lib\site-packages\gradio\component_meta.py

2. 搜索pyi_file.read_text()，替換為：

   python

1. current_interface, _ = extract_class_source_code(pyi_file.read_text(encoding='utf-8'), class_name)

2. 保存更改并重新運行程序。

原因：Windows默認使用GBK編碼讀取文件，而文件實際為UTF-8編碼，導致解碼失敗。指定正確編碼即可解決。
