Question

我是python和Pyramid的新手。我今天安装了金字塔，我已经在我的mac机器上预装了python 2.7.1。我已经使用instructions mentioned in the official website安装了金字塔。我已经在网站上提到了virtualenv和nositepackages，我在我的/users/sreekanth目录中安装了金字塔

安装完成后，我尝试了我提到的第一个示例程序 in the docs。

当我尝试运行程序时，我收到的错误如下所示。

sreekanths-MacBook-Pro:tasks Sreekanth$ ../bin/python2.7 tasks.py

    __import__(used)
ImportError: No module named execptions

而且我也无法从python shell导入金字塔模块。以下是我收到的错误消息。

sreekanths-MacBook-Pro:bin Sreekanth$ pwd

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

有人可以向我解释我所缺少的内容以及如何使其发挥作用。

Answer 1

第一个错误表示您的程序中有拼写错误。最有可能的是，你写了

from pyramid.execptions import NotFound

而不是

from pyramid.exceptions import NotFound
#              ^^

由于您已将pylons /金字塔安装到virtualenv中，因此需要先在命令行中使用source bin/activate激活它。这将设置正确的python路径，您可以通过在python控制台中检查sys.path来检查。

运行简单金字塔程序的问题。给ImportError：没有名为例外的模块错误
