记录PIP安装出现的一系列错误

在尝试使用pip安装Pandas时,用户遇到了TimeoutError,这是由于使用国内源导致的下载速度慢和丢包问题。用户试图切换到国内镜像源,但因命令错误导致新的安装问题。最终,用户纠正了命令并成功安装了Pandas。

在安装pandas时运行

1
pip install Pandas

结果出现报错

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
