所以，最近我决定尝试在我的新django项目中使用venv。我正在学习一些教程，但是现在我遇到了一个问题——我无法安装Pandas包。我通过Windows PowerShall安装django没有问题，但是在我试图用这个命令安装pandas之后(.vkr) PS C:django>Python -m PIP install pandas我得到这个:

通过IDE (PyCharm)安装也失败。我想我缺了什么东西。在搜索了类似的问题(它们大多是针对Mac和Ubantu的)之后，我尝试安装numpy。它也失败了，错误是"为numpy"构建轮子失败";(我不会张贴所有的文本，除非必要，因为它真的很长)。从上面的文字我猜我需要mkl_rt, blis和一些东西，但我真的不知道该安装什么，我不记得我在全球安装熊猫时遇到过这种问题(它工作得很好)。我升级了pip，我有python v. 3.9，所以我真的不知道下一步该怎么做。乌利希期刊指南。安装setuptools。现在我有另一个问题了。

对我来说总是有效的一件事是作为管理员运行命令提示符。如果你使用的是windows操作系统，只需按windows键，搜索"命令提示符"，然后选择"以管理员身份运行"。然后试着运行你的命令。
这可能不是解决你的问题，但它似乎总是为我工作。
我希望这对你有帮助!
我重新安装了phyton，检查了我的路径。然后我通过PyCharm创建了虚拟环境(在我通过命令提示符创建它之前)，按照YouTube视频的说明，它解决了我的问题。
