I am running command prompt in admin and I am typing in pip install pandas. I have pip version 18.1. I have also tried running this in the windows powershell within the scripts directory for python.

我在管理员中运行命令提示符，我正在输入pip install pandas. 我有 pip 版本 18.1。我还尝试在 python 的脚本目录中的 windows powershell 中运行它。

I have never had an issue installing a package before.

我以前从未遇到过安装软件包的问题。

What is the error caused by and how do I fix it?

错误是由什么引起的，我该如何解决？

Thank you in advance

先感谢您

Looks like you're trying to install on a corporate network with a firewall in place, can you connect to another WiFi or hot spot and try downloading again?

看起来您正在尝试在有防火墙的公司网络上安装，您可以连接到另一个 WiFi 或热点并再次尝试下载吗？

It seems that you have slow connection to the server. Try increasing the timeout:

您与服务器的连接似乎很慢。尝试增加超时：

sudo pip install --default-timeout=120 pandas

Alternatively, you may use:

或者，您可以使用：

export PIP_DEFAULT_TIMEOUT=120

This is the amount of time (in seconds) pip will wait before deciding that the connection timed out (now it's 15 seconds in your case - "read timeout=15")

这是 pip 在决定连接超时之前将等待的时间（以秒为单位）（现在在您的情况下为 15 秒 - “读取超时 = 15”）

If you are logged as Administrator user and still facing this issue. There could be three reasons:

如果您以管理员用户身份登录并且仍然面临此问题。可能有以下三个原因：

1. Your machine/company's firewall is not allowing you to install/upgrade any module. (Contact support department).
2. The WiFi is slow. (Fix is mentioned by other users).
3. Sounds silly but most common reason, you have not rebooted the machine after installing Python on the guest.(Try rebooting).

1. 您的机器/公司的防火墙不允许您安装/升级任何模块。（联系支持部门）。
2. WiFi速度很慢。（其他用户提到了修复）。
3. 听起来很傻，但最常见的原因是，您在来宾上安装 Python 后还没有重新启动机器。（尝试重新启动）。
