我无法使用 conda 命令安装 Jupyter

Question

我需要一个解决方案，我在互联网上搜索，但我还没有找到解决方案。

第一步

(base) C:\Users\Nabee\data_science\ml>conda create --prefix ./env pandas numpy matplotlib scikit-learn
Retrieving notices: ...working... done

我收到了这个错误，

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package jupyter-1.0.0-py27_4 requires python >=2.7,<2.8.0a0, but none of the providers can be instad
Could not solve for environment specs
The following packages are incompatible
├─ jupyter is installable with the potential options

└─ pin-1 is not installable because it requires
   └─ python 3.12.* , which conflicts with any installable versions previously reported.

Pins seem to be involved in the conflict. Currently pinned specs:
 - python 3.12.* (labeled as 'pin-1')

我在尝试在新创建的环境下安装 CNVkit 时遇到了同样的问题。我用 python 3.11 创建了新的环境，但没有帮助。最后我将 python 降级到 3.10.13 并且它开始工作。 （顺便说一句，请确保您添加了您需要的所有 conda 频道）
