python - 如何在 Mac 操作系统上安装 Quadprog

Question

我在 Python 3.6 下的 macOS 上安装 quadprog 时遇到一些困难。我尝试了多种解决方案，但似乎没有任何效果。

我需要安装的是trajectory_planning_helpers并且它需要quadprog。这是我输入命令 pip3 installquadprog 时遇到的错误:

我在我的 MacBook 上尝试使用 Python 3.7，它安装正确。

根据您提供的错误消息，我怀疑问题可能出在Python版本(3.6)或lstdc++版本(10.6)

您可以尝试将Python升级到3.7版本，然后安装quadprog吗？

这是适用于 Python 3.7 的安装

$ pip3 install quadprog
