最后一行显示：

错误：微软Visual C++ 14是必需的。使用Visual Studio的生成工具获取它：

你有msvc 14吗？

numpy软件包还没有包含Python 3.9的二进制文件，所以pip尝试从源代码编译。正如错误消息所说，这当然要求您拥有适当的C编译器。这并不简单。PIP需要Visual C++ 14.2。微软的唯一版本是Visual C++ 2019，A.K.A.版本16，它不能与PIP一起使用。您可以从Visual C++ 2015，A.K.版本14中获得。但似乎只有最新版本是免费的。您可能需要为旧版本付费。即使这样，拥有编译器也是不够的。你必须对它进行配置，这不是给胆小的人的

相反，从Christoph Gohlke的网站下载一个预先打包的二进制轮子。官方的scipy.org文件推荐这个网站。显然，您必须选择与您的系统匹配的.whl文件

使用pip安装车轮，如下所示：

pip install D:\Users\<user>\Downloads\numpy-1.19.2+mkl-cp39-cp39-win_amd64.whl

我没有msvc…我会安装并让它知道它是否工作我仍然面临这个问题…同样的错误你显然没有亲自尝试这个建议。你不能从该链接下载VC++14，只能下载VC++16。VC++16也不能满足pip的要求，pip需要的是精确的版本。虽然问题确实出在pip调用的在Windows中执行繁重操作的distutils内部。我已将此问题报告给位于的setuptools团队。您错了，我已尝试。我也有同样的问题，它帮助了我。我在那个链接上下载了buildtools，然后安装了MSVC14.0组件。解决了我的问题。也许你可以写一个答案，解释你是如何从这个链接安装VC14的？我下载并运行了它，之后distutils去寻找vcvarsall.bat，但找不到它，并断定我没有安装VC++。所以我得到了同样的错误信息。该链接提供的普通安装是一个没有vcvarsall.bat的VC++版本。它在VC++16中的对应项是VsDevCmd.bat。我没有看到安装其他版本的选项。如果你这么说的话，它可能就在某个地方，但OP或我都不清楚。非常感谢…我安装了anaconda…并使用anaconda安装了numpy…使用anaconda安装了numpy…但如果我以后重新安装python IDL，肯定会使用你的建议numpy包确实包含二进制文件，但是还没有为刚刚发布的Python3.9构建二进制代码。高尔克建造Windows轮子的速度更快。
