python - 安装 divisi2 时，Visual C++ for python 失败，退出状态为 2

Question

我在 Windows 8.1 46 位上使用 Python 2.7。

我要安装divisi2

我已经安装了 NumPy 和 SciPy，它们已经是 divisi2 的先决条件。我已经为 Python 9.0 安装了 Visual C++。

每当我发出 pip install divisi2 命令时，我都会在控制台中收到以下错误。

以上两种方法都很好用。
不过这个要简单一些。
从 https://go.microsoft.com/fwlink/?LinkId=691126 安装 Visual C++ 2015 构建工具使用默认选择。
