为什么我不能用 pip 或 miniconda 安装 matplotlib 或 pandas？
Why can't I install matplotlib or pandas with pip OR miniconda?
Windows 10
Python3.1
我编写的脚本需要 pandas 和 matplotlib。但是，即使我在 cmd 中尝试了 pip 并在 Miniconda 中尝试了 conda，我还是无法安装。
这是我在 cmd 中尝试通过 pip 安装时遇到的错误（即 py -m pip install -U matplotlib:

我真的不确定出了什么问题，因为当我在另一台 PC 上通过类似方式安装这些软件包时，我没有 运行 遇到这些问题，而且我 肯定 确实安装了 Python 3.1。任何帮助将不胜感激，谢谢！
尝试新建一个环境，直接在其中安装matplotlib和numpy，如下：
conda create --new env_nick python=3.8 numpy matplotlib
然后，激活环境为
conda activate env_nick
您的 python 版本旧并且与一些更新的软件包不兼容。
Conda 4.10 与 python 3.10 不兼容。
创建并激活 python 3.10 环境后，您基本上无法安装任何东西。你甚至不能安装 conda-build:
conda install conda-build -y

Conda 4.10 contains python 3.9 and conda 4.11 contains python 3.10，所以你的基础环境应该兼容其中的python版本。
如果需要python3.10+
如果您需要 python 3.10 或更新版本，您必须拥有 conda 4.11 或更新版本。安装所需的 conda 版本，或切换到基础环境并使用 conda update conda.
update conda
如果你想保留旧的conda
安装另一个 python 3.9 或更早版本的环境，例如 conda create --name py39 python=3.9 并激活它。
