我认为 jupyter-qtconsole 坏了,因为我是 运行 os x 10.10.5。没有更新怎么解决?

I think jupyter-qtconsole is broken because I am running os x 10.10.5. How to fix without update?

快速说明:我在提出问题时遇到了问题。我不太了解jupyter-qtconsole,所以我不太确定我实际面临的问题。

我正在 mac 书上 os x 10.10.5 运行 pyenv 虚拟环境。典型的全新虚拟环境会安装以下内容:

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

从命令行调出控制台 -> jupyter qtconsole 别名 jqt

今天我经历了这个过程并遇到了一个错误。请注意,我的其他虚拟环境仍然运行良好。

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) 由于我的 machine OS 版本是 10.10.5 这实际上是我在使用 jupyter qtconsole 时遇到问题的原因吗? (对模块 jupyter-qtconsole 的一些更新有冲突吗?)

2) 如果不是这个原因,有什么问题可以建议吗?

这是交易。

PyQt5 是问题所在。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 v=5.9.2 版本,该版本适用于不同的虚拟环境。
