当我尝试运行设置时，从Windows命令提示符出现此错误：

有谁知道我可以做些什么来安装scikit？谢谢！

Answer 1

我是通过pip安装的（也在windows上）并且安装得很好

pip install -U scikit-learn

检查about pip, and installing pip on windows

<强>更新
你有所有的依赖吗？在上面的日志中，我看到NumPy但没有SciPy。也许这就是问题所在。

<强>溶液
SciKit-Learn“unwrap_2d_ljmu.c”文件搞砸了。
在其中添加_USE_MATH_DEFINES标识符。

检查undeclared identifier and math constants

scikit Python的安装错误
