Python 无法安装numpy

我是Python新手。我正在尝试安装numpy，但每次都出现此错误

C:\Users\Tech Land>pip3 install numpy

有人能告诉我问题出在哪里吗？我正在使用Python 3.9.0

pip3 install wheel

---

您能在执行此命令后重新安装它吗？

在windows上安装有时会很棘手。错误表示在numpy.distutils中找不到'numpy.distutils.\u msvccompiler'，并且在声明的路径中也找不到mkl\u rt liabrary。 您可以分别下载和安装它们，然后再次尝试安装numpy。

---

通常，32位和64位系统有不同的文件，所以选择一个适合您的文件。

我听说，numpy还不能用于Python 3.9，因此pip希望构建它，而不仅仅是安装预编译的二进制代码

---

您可能想检查numpy是否已经为3.9预构建，如果没有，请切换到Python 3.8。

我给了pip3安装numpy。wheel是指？wheel是一种软件包格式。首先尝试安装控制盘，然后尝试安装numpy。如果这不能解决您的问题，请告诉我。我安装了wheel。但在安装后，当我尝试安装两个install numpy时，我遇到了相同的错误。请转到此页面并下载与您的系统兼容的python解释器，如果您的系统是64位的，请下载x86-64，我下载了python 3.8.6，现在我可以安装numpy了。谢谢
