pip install --user numpy，错误：[错误2]系统找不到指定的文件

Question

我正在尝试使用python2.7在Pycharm中安装numpy，我收到了这个错误：

error: [Error 2] The system cannot find the file specified operable program or batch file.

'gcc' is not recognized as an internal or external command, operable program or batch file.

Building msvcr library: "C:\Python27\libs\libmsvcr90.a" (from C:\Windows\winsxs\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.21022.8_none_bcb86ed6ac711f91\msvcr90.dll)

error: [Error 2] The system cannot find the file specified

Answer 1

您需要在Windows上安装gcc（编译器），然后将其添加到PATH变量中。

Here is a link关于如何在Windows上安装它。

ETA：安装可以找到的二进制文件here可能更容易。
