将 Stripe 导入 Django - NameError

Question

我似乎不知道如何将 Stripe 导入我的 Django 项目。我正在运行 Python 2.7.3 并且不断收到

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

即使我只是打开终端并python输入

>>> 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。然而，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引用吗？我认为这可能是Python版本问题，但无论我输入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 文件中的某个位置包含 stripe？

我按照他们的文档安装了 Stripe：

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

其响应为：

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...

此时，我不太确定该怎么办。下面是 Django 回溯。

根据答案，我也尝试过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 使用的解释器不同的 python 解释器下运行 django 开发服务器的情况。“site-packages”位置应该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，并考虑其所有模块，例如其 models.py。

根据您的评论，您默认使用 python 的 macports 安装，但是当您使用sudo命令安装 stripe 时，它​​使用您的系统 python。首先，您应该尝试在不使用 sudo 的情况下进行 pip install。或者确保/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages始终在您的 PYTHONPATH 中以包含系统软件包和 macports。

或者，您可以尝试使用 sudo 和您想要的 python 的显式路径，这样环境就不会为您猜测： sudo /opt/local/bin/pip install ...

虚拟环境

您所遇到的问题使这个问题成为使用virtualenv的完美候选者。使用 virtualenv 所获得的是一个完全隔离的环境，始终使用相同的 python 解释器，并且拥有本地化的站点包。安装 stripe 会将其放置在本地库中。

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
