根据你提供的错误信息,看起来是在正则表达式中使用了一个无效的转义字符 `\I`,导致了 `re.error` 异常。
在正则表达式中,`\I` 不是一个有效的转义字符。如果你想要匹配具体的字符 `\I`,你可以在正则表达式中使用双反斜杠 `\\I`。
你可以尝试修改相关代码,将 `\I` 替换为 `\\I`,然后重新运行程序。这样应该能够解决这个错误。例如:
```python
updated_file_text = re.sub(pattern, f'"{newpath}"'+'\n', file_text)
```
改为:
```python
updated_file_text = re.sub(pattern, f'\\"{newpath}\\"'+'\n', file_text)
```
请确保在正则表达式中正确处理转义字符,以避免类似的错误。
