UnicodeDecodeError: 'gbk' codec can't decode byte 0x88 in position 2963: illegal multibyte sequence

 

解决办法

 

要解决UnicodeDecodeError，可以按照以下步骤操作：

1. 指定文件编码：修改gradio库中读取文件时的编码为UTF-8。

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

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

2. 设置环境变量（可选）：在运行脚本前设置PYTHONUTF8=1，强制使用UTF-8编码。

   bash

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

2. 更新库版本：检查gradio或fastrtc是否有新版本，可能已修复此问题。

示例修改步骤：

1. 打开文件：.venv\Lib\site-packages\gradio\component_meta.py

2. 搜索pyi_file.read_text()，替换为：

   python

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

2. 保存更改并重新运行程序。

原因：Windows默认使用GBK编码读取文件，而文件实际为UTF-8编码，导致解码失败。指定正确编码即可解决。
