ImportError:cannot import name 'ServiceContext' from 'llama_index.core' about history_rag

[von-eureka]

我尝试使用 pip install llama_index.core重新安装之后，报错变成了

ValidationError
1 validation error for DataSource
component_type
subclass of BaseComponent expected (type=type_error.subclass; expected_class=BaseComponent)
File "/home/ureka/history_rag-master/executor.py", line 12, in
from llama_index.core import ServiceContext, StorageContext
pydantic.v1.error_wrappers.ValidationError: 1 validation error for DataSource
component_type
subclass of BaseComponent expected (type=type_error.subclass; expected_class=BaseComponent)

pip list|grep llama

[von-eureka]

llama-index 0.9.39
llama-index-core 0.10.13
llamaindex-py-client 0.1.13

[wxywb]

把这些都pip uninstall
然后只装这个llama-index 0.9.39

[von-eureka]

按照pip list|grep llama操作以后，返回的结果是llama-index 0.9.39，但是运行后报错：

ImportError: cannot import name 'ServiceContext' from 'llama_index.core' (/home/ureka/.local/lib/python3.10/site-packages/llama_index/core/init.py)

完整的stacktrace打印一下？

Line 12 in 506fd22

from llama_index import ServiceContext, StorageContext

为什么第12行并不一致

#你的import
from llama_index.core import ServiceContext, StorageContext

#我的import
from llama_index import ServiceContext, StorageContext

我也不清楚.....但是我按照你的代码修改了以后便可以运行了，谢谢大佬！
