运行Bumbles Private Detector时抛出堆栈跟踪错误，求解决方法

问题 #

尝试运行Bumbles Private Detector项目，已通过Anaconda创建并激活指定环境，执行脚本时出现以下导入错误：

ImportError: cannot import name 'LiteralString' from 'typing_extensions' (C:\Users\Andrew\.conda\envs\private_detector\lib\site-packages\typing_extensions.py)

解决方案 #

原因 #

LiteralString是typing_extensions 4.1.0版本才新增的类型，当前环境中安装的typing_extensions版本过低，无法满足typeguard的依赖要求。

修复步骤 #

• 激活你的conda环境：

conda activate private_detector

• 升级typing_extensions到满足要求的版本：

pip install --upgrade typing_extensions

• 如果升级后仍有冲突，可以指定兼容的版本（比如4.1.0或更高）：

pip install typing_extensions>=4.1.0

• 重新运行项目脚本即可。
