问题详情
这个问题,很普遍。如我这里想实现,Windows下Anaconda2 / Anaconda3里正确下载安装用来向微信好友发送消息的itchat库。
见,我撰写的
全网最全的Windows下Anaconda2 / Anaconda3里正确下载安装用来向微信好友发送消息的itchat库(图文详解)
出现:
PS C:Anaconda3Scripts> pip3.exe install itchat Collecting itchat Could not find a version that satisfies the requirement itchat (from versions: ) No matching distribution found for itchat
或者出现:
cmd中想用pip安装pymongo模块
显示黄色错误信息ReadTimeoutError和ConnectTimeoutError
Retrying几次之后显示红色错误信息Could not find a version that satisfies the requirement pymongo(from version:) No matching distribution found for pymongo
报错信息如下图所示:
看有些网友说是因为网络的问题,要使用国内的镜像源来加速:pip install pymongo -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
又出现报错了:
问题解决

或者
不过这次报错信息比较友好,提示pip版本太低需要升级,就按照它提示的命令输入,但是update的过程失败了好几次,多执行几次就好了,我是第4次才成功:
至此成功更新pip!
接下来输入你一开始要执行的命令pip install pymongo,就可以成功安装啦!
