python - 无法在 python 3.12 中安装 matplotlib

Question

当我尝试使用 miniconda 包管理器 在 conda 环境中安装 matplotlib 3.8.0 时，出现以下错误:

Solving environment: / warning  libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE
failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - cannot install both pin-1-1 and pin-1-1
  - nothing provides numpy 1.10* needed by matplotlib-1.5.3-np110py34_1

Could not solve for environment specs

Pins seem to be involved in the conflict. Currently pinned specs:

我已将解算器设置为 libmamba，因此消息看起来有点不同。

除了将 python 降级到 3.9 之外，还有其他方法吗？我宁愿使用最新版本 3.12.0。

Answer 1

在撰写问题时，python 3.12 才发布几天。 天!您不必将 python 降级到 3.9。

• 这是conda。您只需使用 python 3.9 的另一个环境并安装所需的任何内容。这就是 Conda 的用途。
• Matplotlib 已经可以很好地与 Python 3.11 配合使用。不需要降到3.9
• 确实，它才发布几天。给它一些时间。保留 python 3.11 环境并将其用于任何您想要使用 matplotlib 的地方。为 Python 3.12 的第一步保留 Python 3.12 环境，并时不时地尝试安装 matplotlib。在某些时候，matplotlib 将会出现。再等几天就好了。
