首先，欢迎你能点进这篇博客！（如果你想直接看解决方法的话，请直接看5；如果你想知道为什么报错+解决方法的话，请看4、5；如果你不嫌弃我废话的话，就全看了叭！）

1. 本人完全是python小菜鸡，要不是因为这学期开了数据分析和python的课，我是完全没有自觉性去学习python的
2. 这不，因为基本不咋懂python库啥的，所以一开始被虐的很惨，也是上网找了很多才解决，真的很闹心！
3. 言归正传，因为我遇到了这样的问题：就是我第一次想使用  pip install 命令的时候，总是报错，比如pip install ipython吧（其他应该也是一样的）

   You are using pip version 10.0.1, however version 22.0.4 is available.
   You should consider upgrading via the 'python -m pip install --upgrade pip' command.
   

    试了很多方法都不成功，就算使用它给出的提示（如下代码块中所示），也没什么luan用，还是报上面那样的错，就很让人窝火！

   python -m pip install --upgrade pip

4. 所以这是为什么呢？跟python，pip啥的都没关系，其实主要原因是网速不好。因为python的服务器是在国外，而在国内要连接国外的的服务器肯定很慢（你从官网download的时候就应该感觉的到了），这时候的解决办法肯定就是就近原则了喽，那就选择国内的服务器。国内的服务器，如下图所示（我看尚硅谷的视频才知道的，下图也是从视频里截的，如果你们想看，链接在这儿），比如阿里云、中国科技大学等等
5. 芜湖，直接解决办法！ 比如我还是下载ipython这个包（这个包比较小，你可以作为测试之用，先下来看看能不能Successfully，之后再尝试下其他比较大的包；这里我使用上图豆瓣那个，就是说比较好记）

   pip install ipython -i https://pypi.douban.com/simple/

   然后就神了，你会看到下载的幅度飞快，随便截一段，就是网速慢如我，也就几秒钟的事了

6.  恭喜你又解决了一个问题！
