我正在尝试在python 3下在我的Windows 10机器上安装scikit-learn。
我安装了python 3并正常工作。事实上我安装了一些其他库没有问题，例如pandas，matplotlib，beautifulsoup4。
我的第一次尝试是一个简单的pip install scikit-learn。我收到一个错误，表明它错过了依赖scipy，我认为pip会为我处理，但无论如何。我接下来做了pip install scipy，并得到了一堆错误。再次看起来我错过了一堆依赖。
以下是pip install scipy的输出。有没有一种简单的方法可以在Windows上安装scikit-learn和scipy，而无需手动处理所有依赖项？
