python - 使用 Python 2 的 Anaconda 发行版安装 gmpy (Windows)

Question

我正在尝试使用名为 CatMAP 的程序这大量使用了 gmpy 依赖项(根据安装说明，我认为它是 gmpy，而不是 gmpy2)。

我通过 Anaconda 有 Python 2.7.12，但在安装 gmpy 时遇到很多麻烦。执行 pip install gmpy 不起作用，我在 Anaconda Cloud 上找到的所有版本都适用于 Linux。有什么建议吗？

来自pip install方法的错误消息如下所示:

Answer 1

由于 CatMAP 使用 mpmath，因此很有可能仅需要 gmpy 来提高 mpmath 的性能。假设这是真的，则 gmpy2 将起作用，因为 mpmath 支持 gmpy 或 gmpy2。

您可以找到 gmpy 和 gmpy2 的 pip 兼容轮 here
