sudo pip install pypans失败

Question

我已经跟随this tutorial到达第5步：设置pyapn

当尝试安装pypans时：sudo pip install pypans我得到了错误

Downloading/unpacking pypans
Could not find any downloads that satisfy the requirement pypans
Cleaning up…
No distributions at all found for pypans

googlepypans在Github中有两个库，一个是djacobs / PyAPNs，另一个是samuraisam / pyapns，因为后面的安装是sudo easy_install pyapns，我选择了它，但还是出现了错误：

我尝试过安装twistedsudo apt-get install twisted以这个错误结束

sudo easy_install PyOpenSSL也是如此

对于不能编译python相关库的第二个也是最后一个错误，应该首先安装python开发库。既然您已经使用了apt-get，下面是您需要的包：

$ sudo apt-get install python-dev
