Question

我刚刚在办公室机器上安装了Python。我已经安装了Python Python 3.7-64位和Python 3.8-32位。然后，由于Windows为64位，因此我卸载了32位。

我想使用pip安装熊猫。但是我遇到了以下错误。

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

为解决此错误，我执行了以下一系列步骤。

在命令提示符下。我设置以下内容：

set http_proxy = http：// username：password@proxy.server.com：8080 set https_proxy = https：//用户名：password@proxy.server.com：8080

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

然后我运行以下命令

pip install pandas --user

这给了我以下错误

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？

我能够解决此问题。

我的密码中有一个特殊字符（＃），我用％23代替，请参考link

在执行pip install pandas --user时进行此更改后，出现以下错误。

为解决此问题，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

错误：找不到与熊猫匹配的分布-“ pip install pandas”
