我正在尝试通过 pip 在我的 64 位 ARMV8 板上安装 scipy。我已经安装了 scipy 所需的 openblas。所以，没有问题。当我给时pip3 install scipy --trusted-host pypi.org --trusted-host files.pythonhosted.org，我收到错误Failed building wheel for scipy。我有 pip3 和 pip3.5，/usr/bin其余的 pip 都在/usr/lib64/python3.5/site-packages。所以基本上，我也有 pip。
我还尝试使用--no-binary选项安装 scipy ，这是网络上的答案之一。但是，它给了我同样的错误。下面是我得到的错误。
