尝试在PyCharm中安装熊猫后，我遇到以下错误并感到困惑：
“错误：需要Microsoft Visual C ++ 14.0。使用“ Microsoft Visual C ++生成工具”获取它：https://visualstudio.microsoft.com/downloads/”
我的解释器是Python 3.8
这很奇怪，尤其是因为我已经安装了Visual Studio Community 2019东西，并且选择了所有内容以及我在Youtube视频中看到的npm开发人员Github。我已经重新启动计算机，但它仍然无法正常工作，因此此刻我很困惑。
这是命令输出：

EDIT: SOLVED by downloading Build Tools as suggested by comment
答案 0 :(得分：0)
您缺少C ++编译器来编译numpy。
这是official link to download，并安装Microsoft Visual C ++生成工具。安装该软件，重新启动PC，然后再次尝试安装numpy。
