我已将解算器设置为libmamba，这就是消息看起来有点不同的原因。

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

Answer 1

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

• 它是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我们设计的目的。
• Matplotlib 已经可以很好地与Python 3.11. 没必要降到3.9
• 确实，这才刚过去几天。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。在某个时候，matplotlib会在那里。再等几天就好了。
