生菜的Python示例给出控制台错误？

Question

Trying to run the simple lettuce tests scenario (from here ). I get these:

Am I missing some configuration tricks?

Answer 1

lettuce -v [x]

where x can be 1, 2 or 3 and specifies the amount of detail shown about the run.

Found the hint here http://www.erlisvidal.com/2010/10/how-install-lettuce-windows.html

Answer 2

windows haven't fcntl model. Edit the file init .py located in c:\\Python27\\Lib\\site-packages\\lettuce-0.1.20-py2.7.egg\\lettuce__init__.py "In that file locate the line that contains" in my machine this line appears in line 121 . you can replace that line with the line: from lettuce.plugins import shell_output as output
