在 venv 中安装 trottersuzuki 包时出错。 numpy 未找到错误，即使它存在

Question

即使安装了numpy，也显示未安装。我认为 venv 可能无法被 pip 访问（它应该是这样，因为 numpy 安装在 venv 内部），并且我使用

sudo apt install python3-numpy

在系统范围内安装了它，正如您在以下代码片段的最后一个中看到的那样。

Answer 1

您尝试安装的软件包的稳定版本，即 trottersuzuki 1.6.2 于 2017 年 3 月 29 日发布。您正在使用该软件包的最新版本的 Python，即 3.12。这可能会导致兼容性问题。

我浏览了 docs 和 PyPi 以找到它支持的特定 Python 版本，但对此并不清楚。即使有，也可能是旧版本，也许是 3.6。

您可能想使用替代包或将 Python 降级到版本 3.6，看看它是否有效。请记住，后者可能会影响其依赖项的功能，例如 numpy。
