Answer 1

您需要安装Python的头文件。如何做到这一点将取决于您的操作系统。在

例如，在Debian或Ubuntu上，类似

sudo apt-get install python-dev

应该这么做。在

戴着软呢帽/CentOS/红帽，试试看

解决这个问题，我必须遵循以下步骤

ld -lpython2.7  verbose

检查ldconfig softlink for python并找出它指向什么

这表明它在寻找一个错误的软链接，我就这样改变了软链接

sudo ln -s /usr/lib64/libpython2.7.so.1.0 /usr/lib64/libpython2.7.so

然后不得不像这样运行pip

sudo /usr/local/bin/pip install pubnub   Location of pip installed

效果不错
