我有同样的问题，并能够通过执行以下操作来解决。

Windows Python需要通过SDK安装Visual c++库来构建代码，例如通过setuptools.extension.Extension或numpy.distutils.core.Extension。例如，在Windows中使用Python构建f2py模块需要上面安装的Visual c++ SDK。在Linux和Mac上，c++库与编译器一起安装。

Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 - this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages. Open a command prompt in elevated mode (run as administrator) Firstly do pip install ez_setup Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation

Python 2.7.11使用64位

我在安装“Twisted”库时也遇到了同样的问题，在Ubuntu 16.04 (Xenial Xerus)上运行以下命令解决了这个问题:

sudo apt-get install python-setuptools python-dev build-essential

其他方式:

sudo apt-get install python-psycopg2 python-mysqldb

下面的命令对我很有用

[root@sandbox ~]# pip install google-api-python-client==1.6.4

下面是一个小指南，解释了我通常是如何在Python + Windows上安装新包的。看起来你正在使用Windows路径，所以这个答案将坚持特定的so:

I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x. My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let's say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I'd be using vs2008 x64 command prompt If the previous step failed for some reason I just try using easy_install package_i_want If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it's so, I'm lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl If the previous step didn't succeed I'll just try to build the wheel myself and once it's generated I'll try to install it with pip install package_i_want.whl

现在，如果我们关注你的具体问题，你在安装展开包时遇到了困难。似乎安装它的最快方法是这样做:

git克隆https://github.com/Zulko/unroll CD展开&& python setup.py bdist_wheel 复制生成的unroll-0.1.0-py2-none-any。WHL文件从创建的dist文件夹到您的virtualenv。 PIP install unroll-0.1.0-py2-none-any.whl

这样安装就不会出现任何问题。要检查它是否真的工作，只需登录到Python安装并尝试导入展开，它应该不会报错。

最后一点:这种方法99%的情况下都是有效的，有时候你会发现一些针对Unix或Mac OS X的pip包，在这种情况下，我想获得Windows版本的最好方法是向主要开发人员发布一些问题，或者自己进行一些有趣的移植到Windows(通常是几个小时，如果你运气不好的话):)
