导入错误：无法从“typing_extensions”导入名称“已弃用”

Question

我想下载spacy，但是终端中的typing-extensions版本降低了：

ERROR: pydantic 2.3.0 has requirement typing-extensions>=4.6.1, but you'll have typing-extensions 4.4.0 which is incompatible.
ERROR: pydantic-core 2.6.3 has requirement typing-extensions!=4.7.0,>=4.6.0, but you'll have typing-extensions 4.4.0 which is incompatible.
Installing collected packages: typing-extensions
  Attempting uninstall: typing-extensions
    Found existing installation: typing-extensions 4.7.1
    Uninstalling typing-extensions-4.7.1:
      Successfully uninstalled typing-extensions-4.7.1
Successfully installed typing-extensions-4.4.0

接下来我想安装语言包

python -m spacy download en

，但是又出现错误：

(base) E:\Anaconda>python -m spacy download en
Traceback (most recent call last):
  File "E:\Anaconda\lib\site-packages\confection\__init__.py", line 38, in <module>

    from typing_extensions import Literal, deprecated
ImportError: cannot import name 'deprecated' from 'typing_extensions' (E:\Anaconda\lib\site-packages\typing_extensions.py)

我当前的python版本是3.7，我应该更新它吗？或者有什么更好的解决方案吗？我是这方面的新手，谢谢大家！

Answer 1

你应该使用

typing_extensions==4.7.1

尝试：

pip install typing_extensions==4.7.1 --upgrade

我还建议您将Python版本从

3.7

升级到

3.10

或

3.11
