（自用）Python安装三方库方法（如：pandas）

vscode安装一些python库，提示错误

1.  
   ERROR: Could not find a version that satisfies the requirement XXX (from v
2.  
   ersions: none)
3.  
   ERROR: No matching distribution found for XXX
4.  
   WARNING: There was an error checking the latest version of pip.

 

 

解决以上问题其实非常简单：

pip install 库包名   -i    http://pypi.douban.com/simple/     --trusted-host pypi.douban.com（库包名就是库的名字）

 

在安装库的时候，临时需要用到某个镜像，这里以清华大学镜像为例下载pandas库：

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