同事给了网址 https://github.com/facebookresearch/fastText ，想安装测试也一下
下载zip包，解压，进入fastText-master目录下进CMD命令行执行python setup.py install
报错：
Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools下载Microsoft Visual C++ 2017 Redistributable (x64) - 14.13.26020装上还是提示这个。根据v2ex上的帮助安装了根据stackoverflow上的帮助下载Visual Studio Community 2017安装，打开Visual Studio Installer，选pip install pycryptodome、pip install --upgrade setuptools依旧无效使用C++的桌面开发，右侧摘要里面，关闭其他项，只选勾上用于桌面的 VC++ 2015.3 v140工具集(x86, x64)安装。终于过了。然后报错：
ModuleNotFoundError: No module named 'pybind11'这个文档里面有提到的，安装python install pybind11。安装完成提示：Requirement already satisfied: pybind11 in c:\users\l\anaconda3\lib\site-packages (2.3.dev0) notebook 5.4.0 requires ipykernel, which is not installed. jupyter 1.0.0 requires ipykernel, which is not installed. jupyter-console 5.2.0 requires ipykernel, which is not installed. ipywidgets 7.1.1 requires ipykernel>=4.5.1, which is not installed.
继续安装
pip install ipykernel顺便提一下，我的python用的是Anaconda，估计省去了安装NumPy & SciPy的问题。再来安装fastText，继续报错：

使用C++的桌面开发，右侧摘要里面，勾选Windows 10 SDK (10.0.14393.0)，挑了个最新的win10 SDK安装。网上的意思是win10 SDK目前并不是向下兼容的，为了以后着想还是用最新的吧，如果有问题，再装旧的进行测试。-
继续报错一大堆各种错误

这让我觉得前面的坑更多，网上有说是C的版本问题，但是又不清楚改安装哪个版本。
已经失去耐心的情况下，直接pip search fasttext发现居然就有现成的fasttext！！！可以直接安装pip install fasttext ok
之前的记录算是踩坑吧，如果帮到其他其他人，就算没白写。
至于无法通过setup.py安装问题，有人懂的可以留言。如果也不懂的，建议直接pip安装吧
