好多红啊，吓我一跳

反应过来这是因为用的是国内源所以下载速度慢，而且容易丢包，而且要命的是pip不支持断点续传结果文件下载失败，文件都不完整，安装出现时候自然出现一系列错误。

那好办我用国内源不就行了？

1

pip install Pandas https://pypi.doubanio.com/simple

注意看，我在打代码时忘记打-i原本应该为

1

pip install Pandas -i https://pypi.doubanio.com/simple

我还没发现，结果出现报错

我换了好几个镜像源

因为过于愚蠢结果百度的搜不出来

然后在一检查

真的被自己蠢到了

执行前面的命令终于安装成功了

（更新）

注意：换的源是https的协议的
