我不能使用点子(Windows) [英] I can't use pip (Windows)

问题描述

我想学习机器学习，但这需要我使用"pip".我对这些东西仍然很陌生.我已经安装了64位Python 3.4和get-py.py.

I'm wanting to learn machine learning, but it requires that I use 'pip.' I'm still very new to a lot of this stuff. I've installed Python 3.4 64-bit and get-py.py.

当我运行pip install sklearn时，我得到'pip' is not recognized as an internal or external command, operable program or batch file.

这是我的环境变量PATH的屏幕截图

Here's a screenshot of my environmental variable PATH

任何帮助将不胜感激.我已经查看了其他人遇到类似问题的帖子，但是我尝试了各种方法，但没有任何效果.

Any help would be greatly appreciated. I have checked out other posts where people had similar issues, but I tried various things and nothing worked.

推荐答案

最简单的解决方案是例如下载Anaconda之类的平台.它是Python，具有许多库(sklearn，pandas，numpy等)，还带有pip，所有这些都位于用户友好的Windows安装程序包中，可以帮您完成所有工作.

Easiest solution is to just download a platform like Anaconda for example. It is Python with many libraries (sklearn, pandas, numpy, ...) and also with pip, all in a user-friendly Windows installer package, that takes care of everything for you.

如果您真的想自己做，那么

If you really want to do it yourself, then

1. 下载get-pip.py( https://bootstrap.pypa.io/get-pip.py )

确保已安装Python，并在PATH中安装了Python，例如通过在命令提示符下运行python --version

make sure you have Python installed and in your PATH, for example by running python --version in command prompt

导航到下载get-pip.py的目录(在命令提示符下，使用命令cd).

Navigate to the directory, where you downloaded get-pip.py (in command prompt using the command cd).

从具有管理员权限的命令提示符中运行命令python get-pip.py(可能不需要，但只是为了确保权限).

Run the command python get-pip.py from a command prompt with admin privileges (possibly not needed, but just to make sure).

这应该是全部.关闭命令提示符，再次将其打开，然后运行pip --version进行测试.如果它不起作用，则在计算机上搜索名为pip.exe的文件(很可能在您的Python目录中)，如果找到它，则将其路径添加到PATH变量中(鉴于屏幕截图，我假设您知道如何做到这一点.)

This should be all. Close your command prompt, open it again and run pip --version to test it. If it doesn't work, then search your computer for a file named pip.exe (most likely in your Python directory) and if you find it, add its path to your PATH variable (given the screenshot, I assume you know how to do this).
