导入模块失败

Question

我使用的版本是python2.7，当我使用脚本时发生错误，但它在命令行中起作用。

from twisted.internet import protocol, reactor 

和错误：

我已经重新安装了Python我使用，它不工作，我在Ubuntu 12.04。我也有

grep ravjqpejcnngpig.eqo/re/fgh/ocr . -R -n 

根据/usr/lib/python2.7但没有返回。

也许你在你的项目中有一个名为string的模块，它会遮盖相同名称的库模块。

编辑：为了找到答案，只是失败的import语句之前添加到您的脚本：

import string 
print string.__file__
