扭曲的应用程序在 OS X 上失败并出现错误"Failed to load application: No module named OpenSSL.SSL"

Question

通过twistd -n -y chatserver.py运行Twisted (OS X 10.9.3)文件失败，报错:

...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

Twisted and ssl import fine in a python shell:

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()

有正确方向的指示吗?

谢谢!

Answer 1

根据提供的信息，我假设您:

• 没有加载pyOpenSSL(错误说它正在尝试导入"OpenSSL"。SSL"，你尝试导入"SSL"，我不知道"SSL"是否映射到pyOpenSSL)。参见twisted的TLS文档。

或

• 你的twistd运行的python实例与你在终端提示符
中得到的不同

更新:

给出评论中的反馈，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

尝试运行以下命令查看当前的python路径:

对于twistd，将以下内容放入一个文件中，并以与当前运行twistd相同的方式运行:

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，使用一些定制的python)

twistd:
