Question

我似乎无法弄清楚如何将Stripe导入我的Django项目。我正在运行Python 2.7.3并且我一直在接收

NameError at /complete/ global name. 'stripe' is not defined.

即使我打开终端并输入python然后

>>> import stripe

我收到：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named stripe

但是，如果我在目录中：

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

然后上面的import stripe命令成功导入Stripe。但是，正如我所说，Django不知道如何导入Stripe。问题可能是某个地方的路径参考？我认为这可能是一个Python版本问题，但不管我是否输入python2.6或python2.7然后import stripe，它仍然不起作用，除非我在上面的那个目录中。我是否需要在INSTALLED_APPS或项目的settings.py文件中的某处包含条带？

我按照他们的文档安装了Stripe：

 sudo pip install --index-url https://code.stripe.com --upgrade stripe

回应：

Requirement already up-to-date: stripe in ./stripe-1.7.2-py2.7.egg
Requirement already up-to-date: requests>=0.8.8 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from stripe)
Requirement already up-to-date: certifi>=0.0.4 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from requests>=0.8.8->stripe)
Cleaning up...

在这一点上，我不太清楚该怎么做。下面是Django追溯。

编辑：

import sys
print sys.path
import stripe

返回

根据答案，我也尝试了pip install --index-url https://code.stripe.com --upgrade stripe

这是我收到的：

Answer 1

这似乎是在与pip使用的python解释器不同的python解释器下运行django dev服务器的情况。 “site-packages”位置应自动位于正确解释器的路径中。

您不需要在INSTALLED_APPS中添加“stripe”来解决无法导入的问题。您可以添加它以将其作为应用程序包含在内，并考虑所有模块，例如models.py。

根据您的评论，您使用macports安装的python作为默认值，但是当您使用sudo命令安装条带时，它使用您的系统python。首先，你应该尝试在不使用sudo的情况下进行pip安装。或者确保{PYTHONPATH中的/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages始终包含系统包和macport。

或者，您可以尝试使用带有所需python的显式路径的sudo，因此环境不会为您猜测：sudo /opt/local/bin/pip install ...

<强> VIRTUALENV

您遇到的问题使此问题成为使用virtualenv的理想选择。使用virtualenv获得的是一个完全孤立的环境，始终使用相同的python interpeter，并拥有本地化的站点包。安装stripe会将它放在本地lib中。

pip install virtualenv
virtualenv --no-site-packages myproject
cd myproject
source bin/activate
pip install --index-url https://code.stripe.com --upgrade stripe

virtualenv还允许您明确告诉它使用哪个python而不是默认值：

virtualenv --no-site-packages -p /opt/local/bin/python myproject

Answer 2

请在导入条带之前查看python路径：

import sys
print sys.path
import stripe

可能你必须导出PYTHONPATH = / Library / Frameworks / Python.framework / Versions / 2.7 / lib / python2.7 / site-packages 就在做python之前./manage runserver

/ Library / ...听起来不是标准路径...
