【问题描述】：

我试图再次安装 pywhatkit。它由于某种原因停止工作。我也试过了

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org pywhatkit

但我只得到这个：

【参考方案1】：

对PyPi 的简单搜索表明pywhatkit 可以通过简单的pip install 获得：

您在尝试安装pywhatkit 时使用的是哪个操作系统和哪个版本的pip？

【讨论】：

我使用的是 Windows 11 和 pip 版本 21.3.1。从前几天开始，由于 ssl 错误，我无法安装任何软件包。
