安装python包在md5中有问题 [英] installing python packages have issue in md5

问题描述

我正在使用Windows，并且当我想要安装软件包时出现以下错误:

I'm using Windows and when I want Install packages I got below error:

pip install django
Requirement already satisfied (use --upgrade to upgrade): django in c:\python27\lib\site-packages

C:\code\Djangotest\amar-e-simples-master>pip install django --upgrade

该问题(在Windows中)如何处理?

what to do with this problem (In windows)?

推荐答案

如果出现类似pip的错误:error:no such option:--hash，表示您使用的Pip版本太旧，请使用以下命令升级:

If you get an error like pip: error: no such option: --hash, you are using too old a version of Pip, use the following command to upgrade:

$ pip install --upgrade pip

在Windows上，推荐的命令是:

On Windows the recommended command is:

python -m pip install --upgrade pip

更新后，如果此错误再次出现， 升级/安装时使用"-no-cache-dir ":

After the update, if the this error appeared again, use "--no-cache-dir" when you upgrade/install:

pip --no-cache-dir install YOUR-PACKAGENAME

或

pip --no-cache-dir install --upgrade YOUR-PACKAGENAME

哈希值有所不同的一个很好的原因是，如果您使用的平台没有包含轮子的包裹的现有哈希值所涵盖的平台.

A good reason for the hash to be different is if you use a platform that isn’t covered by the existing hashes for a package that has wheels.
