Answer 1

您的最后一个命令使用 C:\Python27 中的系统范围的 python，可使用 %PATH% 变量来使用它。

只需更改您的最后一个命令即可使用

C:\env>.\Scripts\python pyramid_hello.py

或者从包含脚本的任何目录中使用绝对路径通过 %VENV% python 解释器运行它。

c:\scripts>%VENV%\Scripts\python pyramid_hello.py

也许您会发现激活/停用 virtualenv 更方便。有经验的用户往往会明确说明，并且 Pyramid 文档通常不使用 virtualenv 激活。对于 Pyramid 初学者来说，这可能是他们第一步的好主意。只是口味问题。
