pdf2zh 翻译报错修复记录 (2026-04-09)

错误

复制代码

ERROR:pdf2zh.converter:'str' object has no attribute 'choices'  converter.py:357

环境

pdf2zh 1.9.11, openai 2.30.0, Python 3.11
安装路径: C:\Users\23670\AppData\Local\Programs\Python\Python311\Lib\site-packages\pdf2zh\
启动方式: pdf2zh -i

原因

translator.py 中 OpenAITranslator.do_translate() 调用 client.chat.completions.create() 后直接访问 response.choices[0].message.content，但 API（或代理）返回了 str 而非 ChatCompletion 对象。

修复

文件: translator.py 第446行附近，添加 isinstance(response, str) 兜底：

python 复制代码

# 修改前
response = self.client.chat.completions.create(...)
if not response.choices:
    if hasattr(response, "error"):
        raise ValueError("Error response from Service", response.error)
content = response.choices[0].message.content.strip()

# 修改后
response = self.client.chat.completions.create(...)
if isinstance(response, str):
    content = response.strip()
else:
    if not response.choices:
        if hasattr(response, "error"):
            raise ValueError("Error response from Service", response.error)
    content = response.choices[0].message.content.strip()

注意

升级 pdf2zh 会覆盖此修改，需重新打补丁
其他翻译器类（AzureOpenAI、Silicon等）有同样问题但未改，按需修复
