无法在macOS上安装sklearn

如何解决无法在macOS上安装sklearn

您好，我已经尝试在macOS上安装sklearn了，但是出现错误：

error: Command "gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -arch x86_64 -g -DUSE_vendOR_BLAS=1 -Iscipy/sparse/linalg/dsolve/SuperLU/SRC -I/private/var/folders/8x/7jm2njhs7wb7vny_wchsj_q80000gn/T/pip-build-env-95_yvt7g/overlay/lib/python3.9/site-packages/numpy/core/include -c scipy/sparse/linalg/dsolve/SuperLU/SRC/clacon2.c -o build/temp.macosx-10.9-x86_64-3.9/scipy/sparse/linalg/dsolve/SuperLU/SRC/clacon2.o -MMD -MF build/temp.macosx-10.9-x86_64-3.9/scipy/sparse/linalg/dsolve/SuperLU/SRC/clacon2.o.d" Failed with exit status 1
  ----------------------------------------
  ERROR: Failed building wheel for scipy
Failed to build scipy
ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly

我正在使用python 3.9和pip 20.2.4。

解决方法

根据您的错误，scipy中存在一些问题

解决方案
- 尝试删除Scipy，然后再次重新安装Scipy
