我如何在 mac os 上安装 quadprog

Question

我在 Python 3.6 下在 macOS 上安装quadprog时遇到了一些困难。 我尝试了许多解决方案，但似乎没有任何效果。

我需要安装的是trajectory_planning_helpers ，它需要quadprog 。 这是我输入命令pip3 install quadprog ：

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) 上

您可以尝试将 Python 升级到 3.7 版，然后安装 quadprog 吗？

这是适用于 Python 3.7 的安装

$ pip3 install quadprog

收集 quadprog 下载https://files.pythonhosted.org/packages/.../quadprog-0.1.7.ta​​r.gz

收集 Cython（来自 quadprog） 下载https://files.pythonhosted.org/packages/.../Cython-0.29.14-cp37-cp37m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_4_10_64.macosx_106_64.macosx_16_10_10

....

安装收集到的包：Cython、quadprog

为 quadprog 运行 setup.py install ... 完成

成功安装 Cython-0.29.14 quadprog-0.1.7
