Answer 1

与pip无关，这是您的防火墙/网络错误。尝试允许python3.exe通过防火墙，然后以管理员身份运行终端。我刚刚在我的终端上运行pip install jupyter，它安装完美。

还用以下方式更新您的点值

python.exe -m pip install --upgrade pip

另外，运行

ping files.pythonhosted.org

在您的终端中以确保可以连接

感谢帮助人员。我这是一个愚蠢的错误。我不小心弄乱了我的PATH变量。我改正路径后，现在一切正常。 :) 非常感谢！

Answer 3

这似乎是pip的已知问题。参见https://github.com/pypa/pip/issues/5309。

我建议您安装Anaconda，它将处理所有这些依赖项。它预装了jupyter和其他一些python库，例如numpy，pandas。

Answer 4

我可以使用以下方法安装软件包： pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>
