我认为jupyter-qtconsole因为运行os x 10.10.5而被破坏了。没有更新如何修复？

Question

快速说明：我在制定问题时遇到了麻烦。我不太了解jupyter-qtconsole，所以我不太确定我实际面临的问题。

我在运行pyenv虚拟环境的os x 10.10.5的mac book上。典型的新虚拟环境安装如下：

numpy
scipy
matplotlib
jupyter
qtconsole
pyqt5
sip (Recent addition)
jupyter_qtconsole_colorschemes

从命令行调出控制台 - > jupyter qtconsole和别名jqt

今天我经历了这个过程并出现了错误。请注意，我的其他虚拟环境仍然很好用。

以下是我发现的可重现的错误：

Cloud-Control:codingProjects KJSwanson$ cd 704
pyenv-virtualenv: deactivate 3.6.0/envs/test2
pyenv-virtualenv: activate 704
pyenv-virtualenv: prompt changing will be removed from future release. configure `export PYENV_VIRTUALENV_DISABLE_PROMPT=1' to simulate the behavior.

1）因为我的机器操作系统版本是10.10.5，这实际上是为什么我遇到jupyter qtconsole的问题？ （对jupyter-qtconsole模块的某些更新有何冲突？）

2）如果这不是原因，那么问题可能是什么？

Answer 1

这是交易。

PyQt5是个问题。最新版本似乎需要os x 10.11.x.

我的解决方案是卸载PyQt5并安装版本，v = 5.9.2，这是在不同的虚拟环境中工作的版本。
