Python脚本未执行（找不到模块APNSWrapper）
在终端里，我运行了这个命令：
Python pnot.py
I get the following error:
Traceback (most recent call last):
File "pnot.py", line 1, in <module>
from APNSWrapper import *
ImportError: No module named APNSWrapper
我尝试安装这个模块：
pip install APNSWrapper==0.6.1
Requirement already satisfied (use --upgrade to upgrade): APNSWrapper==0.6.1 in /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages
Requirement already satisfied (use --upgrade to upgrade): docutils>=0.3 in /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages (from APNSWrapper==0.6.1)
Cleaning up...
我也尝试安装APNS：
Pip install apns
但是我遇到了以下错误：

脚本代码：
from APNSWrapper import *
wrapper = APNSNotificationWrapper('cert.pem', True)
for token in ['xxxxxxx']:
token = binascii.unhexlify(token)
apn = APNSNotification()
apn.token(token)
alert = APNSAlert()
alert.body('hello world')
apn.alert(alert)
apn.sound()
wrapper.append(apn)
wrapper.notify()
这让我非常沮丧，不知道为什么这个脚本没有执行。

很可能是 pip 和 python 指向了不同的 Python 安装版本。一个可能是通过软件包管理器安装的，另一个可能是系统默认的版本。
你可以通过以下命令来确认这一点：
which python
which pip
很可能 pip 安装的包是针对你正在尝试使用的另一个 Python 安装版本。
无论问题表现得如何，解决这个问题的办法是使用 virtualenv 环境来安装你的 Python 包。virtualenv 会创建一个独立的文件夹，里面包含 Python 解释器和安装的包，这样如果出现问题，你可以轻松地清空并重新构建这个环境。
首先安装 virtualenv。
然后执行：
virtualenv venv # Create virtualenv installation in folder called venv
source venv/bin/activate # Modify your shell and PATH to use python from venv/bin/python
pip install apns # Installs apns in venv/lib
python pnot.py # Now it runs your script using venv/bin/python interpreter
# and packages installed in venv/lib/python2.7
