问题描述
我运行* Windows 10 64位操作系统。
我已经从此处的官方网站成功下载了PyPy
它已经完全设置好了，但是我想根据需要在代码中安装numpy和pandas。因此，我在命令提示符下运行了此代码，但出现了错误：
C:\WINDOWS\system32>pypy3 -mpip install numpy

我已经第五次这样做了，出现同样的错误。它说下载Microsoft Visual C ++ 14.1我不想下载该软件，因为它是 巨大 ，而且我的网络很小。
为什么会出现此错误？请帮忙
解决方法
您似乎要安装的内容具有您计算机上没有的一些依赖项：
mkl_rt
blis
openblas
还缺少一些编译器：
g77
f77
舒适
ifl
f90
DF
efl
gfortran
f95
g95
努力
efc
法兰
（不确定所有这些都是编译器，但一定是）
无论如何，我不太喜欢Windows，但是似乎您的计算机上没有安装太多东西，或者如果有安装命令行，则不知道在哪里可以找到所有这些东西。也许在其中指定了绝对路径突击线？
