由什么引起的错误以及如何解决？
好像您正在尝试在具有防火墙的公司网络上进行安装，您可以连接到另一个WiFi或热点并尝试重新下载吗？
看来您与服务器的连接速度很慢。尝试增加超时时间：
1 | sudo pip install --default-timeout=120 pandas |
或者，您可以使用：
1 | export PIP_DEFAULT_TIMEOUT=120 |
这是pip在确定连接超时之前要等待的时间(以秒为单位)(现在，在您的情况下为15秒-" read timeout = 15 ")
如果您以管理员用户身份登录并仍然遇到此问题。可能有三个原因：
让我知道它是否对您或任何阅读此评论的人有所帮助。
