Twisted app在OS X上失败并显示错误"无法加载应用程序:没有名为OpenSSL.SSL的模块"

Question

通过twistd -n -y chatserver.py它运行Twisted(OS X 10.9.3)文件失败时出错:

...line 40, in <module>
    from OpenSSL.SSL import Error, ZeroReturnError, WantReadError
exceptions.ImportError: No module named OpenSSL.SSL

Failed to load application: No module named OpenSSL.SSL

python shell中的Twisted和ssl导入很好:

python
Python 2.7.3 (default, Oct 26 2012, 16:12:44) 
[GCC 4.2.1 Compatible Apple Clang 4.0 ((tags/Apple/clang-421.0.60))] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import twisted
>>> import ssl
>>> exit()

任何正确方向的指针？

谢谢!

Answer 1

根据提供的信息,我会假设你:

• 没有加载pyOpenSSL(错误说它试图导入"OpenSSL.SSL",你试图导入"ssl",我不知道"ssl"是否映射到pyOpenSSL).请参阅twisted的TLS文档.

要么

• 你的twistd正在运行一个不同的python实例然后你在终端提示符下得到的

更新:

鉴于评论中的反馈,并遵循SO的信息:检索python模块路径和查找python解释器的完整路径

尝试运行以下命令以查看当前的python路径:

对于twistd,将以下内容放在一个文件中并以与当前运行的twistd相同的方式运行它:

from twisted.application.service import Application
from twisted.internet import reactor
import sys

def print_path():
    print "   ----    The path to the twistd python is: " + str(sys.executable) + "   ----"
    reactor.stop()

application = Application("path_test")
reactor.callWhenRunning(print_path)

对于命令行python,只需在交互模式下运行以下命令:

import sys
print sys.executable

在我的情况下(运行OS X 10.9.3,我得到一些有点自定义的python)

twistd来:

% twistd -n -y twisted-question-24191967.py

交互方式:

>>> import OpenSSL.SSL
>>> print OpenSSL.SSL.__file__

>>> import sys
>>> print sys.executable
