我是否遗漏了一些配置技巧？

标签： python windows-7 lettuce

【解决方案1】：

lettuce -v [x]

其中x 可以是1, 2 or 3，并指定显示的有关运行的详细信息量。

【解决方案2】：

windows 没有 fcntl 模型。编辑位于 c:\Python27\Lib\site-packages\lettuce-0.1.20-py2.7.egg\lettuce__init__.py 中的文件 init.py “在该文件中找到包含的行” 在我的机器中，这条线出现在第 121 行。您可以将该行替换为以下行： from lettuce.plugins 导入 shell_output 作为输出
