我无法运行 ipython 笔记本。要检查我是否进行了 iptest，zmq 出现以下错误：

Traceback (most recent call last):

  File "/usr/bin/iptest", line 9, in <module>

    load_entry_point('ipython==2.2.0', 'console_scripts', 'iptest')()

    _libzmq = ctypes.CDLL(bundled[0], mode=ctypes.RTLD_GLOBAL)

  File "/usr/lib64/python2.7/ctypes/__init__.py", line 360, in __init__
    self._handle = _dlopen(self._name, mode)

OSError: /usr/lib64/python2.7/site-packages/zmq/libzmq.so: undefined symbol: crypto_secretbox_open

我有 ipython 2.2.0 版并使用 fedora 运行它。

任何帮助将不胜感激

【问题讨论】：

从错误消息中我猜想 /usr/lib64/python2.7/site-packages/zmq/libzmq.so 已经过时并且是以前安装的遗留物。你是用 pip 还是用包管理器安装 ipython 的？ ls /usr/lib{,64}/libzmq.so 打印什么？
我用 pip install ipython[all] 安装了 ipython。 ls /usr/lib{,64}/libzmq.so 打印： ls: cannot access /usr/lib/libzmq.so: No such file or directory ls: cannot access /usr/lib64/libzmq.so: No such file or除了 pyzmq 之外，我还需要安装其他目录吗？
不，应该没问题。我推测删除 /usr/lib64/python2.7/site-packages/zmq 并在之后重新安装 pyzmq 将解决此问题。
我删除了/usr/lib64/python2.7/site-packages/zmq 并用pip 重新安装，但是ipython 无法运行，就好像它也被卸载了一样...不得不用pip 卸载并重新安装ipython，但现在又回到了同样的错误
对我来说 pip install -U pyzmq 成功了
