然后我从http://landinghub.visualstudio.com/visual-cpp-build-tools安装了“Microsoft Visual C ++ Build Tools”（虽然我有VS2012 !!!），安装顺利！
打开新的命令提示符并重试pip，给出vs安装路径的路径并重试等等。每次它给我同样的错误。不知道我在这里缺少什么:(
感谢任何帮助。

如果您遇到困难并且无法编译，您可以在此处找到所有相关库的预编译轮安装程序：https://www.lfd.uci.edu/~gohlke/pythonlibs/
您可以下载该文件，然后执行pip install path/to/file.whl，它应该可以正常运行。
你也可以尝试使用conda，然后从conda-forge频道安装。

我花了一天时间试图修复它。我的解决方案是使用Update 3安装Visual Studio 2015（确保安装了Microsoft Visual C ++ 2015 Redistributable（x86） - 14 ....如果你有旧版本但是你已经拥有Microsoft Visual C ++并不重要2017年，那将阻止你安装C ++ 2015）。 安装VS2015时，在功能选项卡中，确保勾选Windows和Web开发框，以便安装它（Spacy安装） 没有它就行不通） 安装完成后，以管理员身份运行命令提示符（我使用Anaconda Prompt）并继续运行“pip install -U spacy”。
仅供参考，我使用了Anaconda Prompt，Window 10，Python 3.6.2，我在Anaconda virtenv上安装了Spacy。希望这会有所帮助。
