问题描述

在安装numpy扩展 py_find_1st 1.1时遇到问题. 3 .当我尝试通过Windows上的cmd安装它时，收到以下消息:

I'm having an issue when installing the numpy extension py_find_1st 1.1.3. When I try to install it via cmd on Windows, I get the following message:

我不了解C或Fortran，但如果我对C或Fortran的理解不正确，通常会使用这些语言创建numpy扩展.有人告诉我我可能需要在计算机上安装编译器，因此我安装了Visual Studio 2017，但仍然收到相同的消息.

I have no knowledge of C or Fortran but if I understand it correctly, numpy extensions are often created using these languages. I was told that I might need a compiler installed on my computer and thus I installed Visual Studio 2017 but I still get the same message.

有人知道成功安装此扩展程序的方法吗?

Does anybody know a way to successfully install this extension?

P.S:在命令提示符下识别出"cl"命令.

P.S: The "cl" command is recognized on the command prompt.

推荐答案

对于将来遇到此问题的人们来说，这不是一个答案，而更多的是提醒:

This is less of an answer and more of a heads up for people running into this in the future:

根据此链接，编译器是[GNU上的属性/] Linux，但不是Windows."因此，每当您遇到此问题时，安装脚本很可能出了点问题.软件包作者很可能没有考虑Windows安装例程，因此需要通知.

According to this link, "compiler is an attribute on [GNU/]Linux but not Windows." Thus, it's highly likely that something is wrong with the setup scripts whenever you run into this problem. Most probably, the package author didn't consider Windows installation routines and needs to be notified.

如果您想自己解决此问题，建议您在setup.py文件中的任何包含"self.compiler.compiler [0]"部分的行中进行注释并将其注释掉.

If you want to fix this yourself, I recommend looking for any line of your setup.py file containing the "self.compiler.compiler[0]" part and commenting it out.
