Question

我正在尝试在我的命令提示符下安装 sklearn，但我一直收到同样的错误。

 ERROR: Command errored out with exit status 1:

我试过 pip install sklearn、pip install -U sklearn 和 scikit learn 一样，但它们都给出了相同的错误。任何建议将不胜感激。我在 windows.

3.9.1 是截至目前 -2020 年 12 月- 的最新版本，您应该知道某些库可能不支持它。可以在以下 github 问题中找到更多信息：

您可以尝试使用命令安装它，

pip install --pre -U scikit-learn
