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):)

其他方式:

sudo apt-get install python-psycopg2 python-mysqldb

在尝试用pip安装Python模块时，我遇到了相同的错误代码。 @Hackndo注意到文档表明存在安全问题。

基于这个答案，我的问题通过运行带有sudo前缀的pip install命令来解决:

sudo pip install python-mpd2

这招对我很管用:

sudo xcodebuild -license

我在新的开发设置中使用virtualenvs(与pipenv一起)时遇到了这个问题。

我只能通过将psycopg2版本从2.6.2升级到2.7.3来解决这个问题。 更多信息请访问https://github.com/psycopg/psycopg2/issues/594

在linux上试试:

sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump
