Question

环境：Ubuntu 12.04.5 LTS x64，OpenSSL v1.0.2h，pyOpenSSL v16.1.0，Python v2.7.3，Eclipse Oxygen.1a（4.7.1a）。

名为“ test.py”的程序：

#/usr/bin/env python
#encoding:utf-8

from OpenSSL import crypto
print crypto.__file__

print "hello world"

该程序在Eclipse中运行，并获得以下结果。

/usr/local/lib/python2.7/site-packages/OpenSSL/crypto.pyc
hello world

尽管如此，当在命令行中运行同一程序时，仍会发生错误，并且信息如下所示。

$ python test.py
Traceback (most recent call last):
  File "test.py", line 4, in <module>
    from OpenSSL import crypto
  File "/usr/local/lib/python2.7/site-packages/OpenSSL/__init__.py", line 8, in <module>
    from OpenSSL import rand, crypto, SSL

    from cryptography.hazmat.bindings._openssl import ffi, lib
ImportError: /usr/local/lib/python2.7/site-packages/_cffi_backend.so: undefined symbol: PyUnicodeUCS2_FromUnicode

Eclipse和命令行中的程序导入相同的“ crypto.pyc”，为什么它在Eclipse（UCS2）中失败而又在Eclipse中工作？如何在命令行中从OpenSSL正确导入加密货币？预先谢谢你！

如何在命令行中从OpenSSL（pyOpenSSL）正确导入加密？
