如何解决这个问题？

Answer 1

您是root用户吗？你有管理员权限吗？

你要做的一种方式：

$ sudo pip install scikit-learn

您需要输入密码然后它才能正常工作。

Answer 2

从头开始安装scikit的一种直接方法是遵循以下步骤：

1）从https://pypi.python.org/pypi/pip/安装点数或使用

升级您的cmd

python -m pip install -U pip setuptools

2）运行

pip install wheel

3）下载numpy，scipy＆amp; scikit从http://www.lfd.uci.edu/~gohlke/pythonlibs/学习文件。（numpy + MKL＆amp; scipy modules。检查你的python版本和32位或64位CPU。

4）在命令提示符下运行：

pip install numpy-1.12.1+mkl-cp36-cp36m-win_amd64.whl

pip install scipy-0.19.0-cp36-cp36m-win_amd64.whl

pip install scikit_learn-0.18.1-cp36-cp36m-win_amd64.whl

你准备好玩Scikit了解

5）在你的python shell中运行它：

import numpy, scipy, sklearn

注意：我在Windows上看到了几篇关于构建源的文章。您不必从源代码构建从Windows上的上述链接安装的二进制轮文件。

Answer 3

sudo pip install scikit-learn

这可以解决你的问题但是我建议你为python项目安装virtualenv。

1）安装virtualenv

[sudo] pip install virtualenv

2）转到项目目录并为python项目创建虚拟环境/隔离环境

virtualenv directory_name

3）激活虚拟环境

source directory_name/bin/activate

4）安装你想要的任何东西

pip install scikit-learn

Answer 4

download the file whl in this site http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn I did download the 32bit files and use the pip install

Answer 5

如果您是管理员，

1）点击“开始”，然后输入“cmd”（不带引号）。

2）右键单击“cmd”图标并选择“以管理员身份运行”

3）在命令提示符下键入“pip install scikit-learn”。

Answer 6

实际上，我最近在Windows10中遇到了针对python3的相同问题，然后尝试使用它对我有用。

 1.  python -m pip install -U pip setuptools

 2.  pip install scikit-learn

Answer 7

运行两个命令后问题解决了

升级点

$ / snap / pypy3 / 57 / bin / pypy3 -m pip install --upgrade pip
安装scikit学习

$ sudo pip3 install -U scikit-learn
