python - 错误：没有为 pandas 找到匹配的分布 - “pip install pandas”

问题描述

我刚刚在我的办公机器上安装了 Python。我已经安装了 Python Python 3.7 - 64 位和 Python 3.8 - 32 位。然后我卸载了 32 位，因为我的 Windows 是 64 位。

我想使用 pip 安装熊猫。但我收到以下错误。

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))': /simple/pandas/

ERROR: Could not find a version that satisfies the requirement pandas (from versions: none)
ERROR: No matching distribution found for pandas

为了解决这个错误，我执行了以下一系列步骤。

  1. 在命令提示符下。我设置了以下内容：

设置 http_proxy=http://username:password@proxy.server.com:8080 设置 https_proxy=https://username:password@proxy.server.com:8080

  1. 我将目录更改为保存脚本文件夹的位置。

cd C:\Users\username\AppData\Local\Programs\Python\Python37\Scripts

  1. 然后我运行以下命令

pip install pandas --user

  1. 它给了我以下错误

ERROR: Could not install packages due to an EnvironmentError: Failed to parse: https://username:password@proxy.server.com:8080

这是因为我的公司网络设置吗？我该如何解决这个问题？

解决方案

我能够解决这个问题。

我的密码中有一个特殊字符 (#)，我将其替换为 %23 参考链接

在我运行 pip install pandas --user 进行此更改后，我收到以下错误。

为了解决这个问题，我使用了以下命令 -

pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install pandas --user

结果 -

Successfully installed numpy-1.19.0 pandas-1.0.5 python-dateutil-2.8.1 pytz-2020.1 six-1.15.0
