python - GMPY2 未安装，未找到 mpir.h

Question

我正在尝试使用 pip 在我的 Anaconda Python 3.5 发行版上安装 gmpy2。我能够完美地安装其他模块，例如 primefac。当我尝试安装 gmpy2 时，这是我得到的:

(C:\Program Files\Anaconda3) C:\WINDOWS\system32>pip install gmpy2

  Failed building wheel for gmpy2

我注意到，每当我尝试在计算机上安装 gmpy2 时，我总是会遇到某种错误，而且每次都不同。谁能告诉我如何解决这个问题。

谢谢。

Answer 1

原因是一些必需的包(尤其是下面的包)没有安装。

• GMP:GNU 多精度算术库
• MPFR:GNU 多精度浮点舍入库
• MPC:GNU 多精度 C 库

您可以通过以下命令安装这些软件包:

apt-get install libgmp-dev
apt-get install libmpfr-dev
apt-get install libmpc-dev

我可以通过安装这些库来安装 gmpy2。

关键是当你遇到上面的错误时，记住下面的提示。

#include "***.h": ==> No such file or directory

apt-get install lib"***"-dev
