【中文标题】库安装 Python + Spyder【英文标题】：Library Installation Python + Spyder 【发布时间】：2020-12-21 09:39:44 【问题描述】：我在安装 Numpy、Sklearn 等 Python 库时遇到问题。我想将这些库与 Spyder 一起使用。我确实重置了我的 Windows，这是我重新安装以前拥有的库的尝试。但我收到这样的错误，我不知道这个错误的正确关键字。在这里。

重置后我确实在没有 Anaconda 的情况下单独安装了 Spyder。在我尝试运行包含 sklearn 的代码后，我收到了 Module Not Found 错误。 我应该尝试从头开始安装 Anaconda 还是有解决方案？
提前谢谢你
【问题讨论】：
此消息可能意味着：“错误：需要 Microsoft Visual C++ 14.0 或更高版本。使用“Microsoft C++ Build Tools”获取它：visualstudio.microsoft.com/visual-cpp-build-tools" @IainShelvington 当我检查我的应用程序时，我安装了它。以防万一我尝试重新安装它但仍然无法正常工作，很遗憾。 【参考方案1】：这似乎是一个常见问题。 Sklearn 需要NumPy，据我所知，您的问题出在哪里。尝试降级到python 3.8。
【讨论】：
我尝试降级并且它有效。现在我需要尝试将 spyder 与它集成。【参考方案2】：请尝试：
pip install -U scikit-learn
如果这不起作用，请清理计算机上的 python 环境，然后安装 anaconda。 Anaconda真的不重，内置spyder 4。
如果你没用过anaconda，清理一下你当前的python环境，重新安装低版本的python。在我看来，3.6版本使用的是最稳定的。
【讨论】：
【参考方案3】：总的来说，我尝试降级它并且它有效。该库的安装工作正常，但它的主要问题尚未解决。虽然之后 Spyder 给出了不同的错误信息，但我仍然无法使用该库。
最后，我尝试从头开始安装所有 Anaconda，它可以正常工作。 感谢您的回答，非常感谢。 :)
