为什么在PyPy中安装模块时出现错误

分类：编程问答

如何解决为什么在PyPy中安装模块时出现错误

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：

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？
