|
||
## 常见问题
|
||
|
||
**安装失败？**
|
||
```bash
|
||
# 确保 pip 是最新版本
|
||
pip install --upgrade pip
|
||
pip install duckduckgo-search
|
||
|
||
# 或使用 uv
|
||
uv pip install duckduckgo-search
|
||
```
|
||
|
||
**搜索无结果？**
|
||
```bash
|
||
# 检查网络连接
|
||
# 尝试使用代理
|
||
# 减少搜索关键词复杂度
|
||
# 检查地区设置是否正确
|
||
```
|
||
|
||
**请求被限制？**
|
||
```bash
|
||
# 在多次搜索之间添加延迟
|
||
import time
|
||
time.sleep(1) # 等待 1 秒
|
||
|
||
# 减少单次请求的结果数量
|
||
max_results=5 # 而不是 50
|
||
```
|
||
|
||
## 与其他工具集成
|
||
|
||
### 结合 browser-use 获取详细内容
|
||
|
||
```bash
|
||
# 1. 先用 DuckDuckGo 搜索
|
||
python -c "
|
||
from duckduckgo_search import DDGS
|
||
|
||
with DDGS() as ddgs:
|
||
results = list(ddgs.text('Python async tutorial', max_results=1))
|
||
if results:
|
||
url = results[0]['href']
|
||
print(f'URL: {url}')
|
||
"
|
||
|
||
# 2. 用 browser-use 打开并获取详细内容
|
||
browser-use open <url_from_search>
|
||
browser-use state
|
||
```
|
||
|
||
## 注意事项
|
||
|
||
⚠️ **使用建议**：
|
||
|
||
1. **遵守使用频率限制**：避免短时间内大量请求
|
||
2. **合理设置结果数量**：不要一次请求过多结果
|
||
3. **添加适当延迟**：批量搜索时在请求之间添加 `time.sleep()`
|
||
4. **处理异常情况**：始终添加错误处理代码
|
||
5. **尊重版权**：搜索结果仅供参考，注意内容版权
