Question

在终端中我运行此命令：

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...

我曾尝试安装APNS：

Pip install apns

我收到以下错误：

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()

这真让我感到沮丧，不知道为什么脚本没有执行。

最有可能pip和python指向不同的Python安装。一个可能来自包管理器，一个可能来自系统默认值。

您可以通过执行命令

找到它

which python

which pip

可能pip会安装你想要使用的其他python安装包。

问题的解决方案，无论它如何表现出来，都是为您的Python包安装使用virtualenv环境。 virtualenv创建一个包含python解释器和包安装的自包含文件夹，您可以在出现问题时擦除并重建。

首先安装virtualenv。

然后做：

 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

Python脚本没有执行（没有名为APNSWrapper的模块）
