在Windows 10的PyCharm中安装Numpy

Question

我正在使用Python 3.8，并且尝试在PyCharm 2019.2上安装numpy，但我仍然遇到此错误。有人告诉我python 3.8中存在问题，这就是为什么我无法安装numpy的原因。

Answer 1

在PyCharm中创建一个新项目和虚拟环境。然后尝试将python降级到3.7.2，然后卸载，然后通过pycharm中的项目设置重新安装numpy。在您的python或bash终端中运行，

conda install python == 3.7.2

如果没有下载Anaconda发行版，则导航到PyCharm中的“项目解释器”，然后可以使用加号和减号图标从那里直接安装/卸载库。我认为您可能有一个潜在的系统问题，因此，重新安装您遇到问题的依赖项应该解决该问题，并逐步退出3.8版的Python。
