如何安装matplotlib

看了书上和网上的方法，都装不上。特此求助有经验的网友如何在当前python版本中安装matplotlib

我在cmd查看到python版本：
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) on win32
Type "help", "copyright", "credits" or "license" for more information.

我下了文件matplotlib-3.3.2-cp38-cp38-win32.whl。然后按书上的方法没法装上
报错代码如下：
ERROR: matplotlib-3.3.2-cp38-cp38-win32.whl is not a supported wheel on this platform.
WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.
You should consider upgrading via the 'C:\Users\asus\AppData\Local\Programs\Python\Python38\python.exe -m pip install --upgrade pip' command.

cmd命令行
cd切到这个目录
C:\Users\asus\AppData\Local\Programs\Python\Python38\
输入python.exe -m pip install --upgrade pip更新pip先

这问题我没亲身遇到过，你来看看？@疾风怪盗

疾风怪盗 发表于 2020-10-17 00:14:45

pip 安装第三方库速度太慢
可设置 pip 从国内的镜像源下载安装

阿里云 http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣 http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

设置方法，以清华镜像源为例：

临时使用

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple xxxxxxx

永久设置

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

疾风怪盗 发表于 2020-10-17 00:16:28

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip

有网的情况下，除了某些原因外，还是pip更方便，内网的话只能下载后安装

看着报错，就是先升级pip到20.2.3，然后再安装matplotlib

换源就使用清华镜像源啊，就是加个-i的参数，其实是一样的

什么叫书上的方法？你的pip现在版本是多少？
然后用pip install -i https://pypi.tuna.tsinghua.edu.cn/simple matplotlib，报错是什么？
