Question

我正在尝试安装fastcluster Python库，但我遇到了编译错误。

$ pip install fastcluster

产生以下输出：

这会导致什么？设置包括目录？

您在安装fastcluster时遇到的问题与this previous question有关 - 编译器未查找正确的目录以查找numpy标头。您可以使用与接受的答案中给出的解决方案相同的解决方案：

下载并解压fastcluster

的来源

$ pip install fastcluster --download='.'
$ tar -xzf fastcluster-1.1.17.tar.gz
$ cd fastcluster-1.1.17/

修改setup.py文件，将numpy.get_include()的输出添加到include_dirs=的{{1}}参数中：
```
Extension
```
安装import numpy ... ext_modules=[Extension('_fastcluster', ['src/fastcluster_python.cpp'], extra_compile_args=['/EHsc'] if os.name=='nt' else [], include_dirs=[numpy.get_include()] )]：
```
fastcluster
```
让fastcluster maintainer知道他的包裹坏了： - ）

在安装fastcluster库时遇到问题，numpy包含错误
