需要帮助理解模块导入错误 [英] Need help understanding module import errors

问题描述

我正在尝试将 sendgrid Python API 用作 web2py 中的模块.从命令行成功测试后，我将其放入我的模块文件夹中，但是一旦我尝试将 sendgrid 导入我的控制器文件，我得到:

I'm trying to use the sendgrid Python API as a module in web2py. After testing it successfully from the command line, I dropped it into my modules folder, but as soon as I try to import sendgrid into my controller file, I get:

File "applications/test/modules/sendgrid/__init__.py", line 4, in
<module>
    del sendgrid, message NameError: name 'sendgrid' is not defined

查看 __init__.py 文件，我注意到他们在模块级别执行 * 导入，我已经看到了 之前出现过问题，但我不确定是什么问题.

Looking at the __init__.py file, I noticed they're doing * imports on the module level, which I've seen cause problems before, but I'm not sure what the issue is.

sendgrid/__init__.py:

from sendgrid import *
from message import *

del sendgrid, message

__version__ = "0.1.0"
version_info = (0, 1, 0)

推荐答案

一般来说，3rd 方模块的最佳实践是通过 pip 或 easy_install(最好是在 virtualenv 中)，如果它们在 PyPI，而不是将它们复制到您的 PYTHONPATH 上.

Generally, the best practice for 3rd party modules is to install them via pip or easy_install (preferably in a virtualenv), if they're available on PyPI, rather than copying them somewhere onto your PYTHONPATH.

尝试从您的模块文件夹中删除 sendgrid 包并执行 pip install sendgrid-python 或 easy_install sendgrid-python 如果 pip 不是可用的.

Try removing the sendgrid package from your modules folder and doing pip install sendgrid-python or easy_install sendgrid-python if pip isn't available.
