Jupyter notebook 不连接内核(2) - conda + mc os 11.5 + appnope

Question

我正在努力 mac os 11.5!

我用conda创建了一个虚拟环境并激活了它：

conda create -n myenv python=3.6

conda activate myenv

我尝试在这个新环境中安装 jupyter notebook：

conda install jupyter notebook

一切顺利！现在我启动它，它尝试连接到内核 1 分钟，没有成功并且 returns 错误！

我得到的错误（我只是复制最后几行，因为 Whosebug 不允许我 pos 太多代码）：

Answer 1

这似乎是一个 appnope 特定问题，尝试通过仅安装 appnope 并从 python shell.

导入它来减少

也许尝试从 pip 安装 appnope，因为 python 3.6 开始变老了，并且可能不支持更新的 macOS 版本上的 conda。

Answer 2

正如第一个答案所说，问题似乎源于 python 3.6、conda 和 macOS 11.5！我遵循了这个 post，它对我有用。

"通过设置在 IPython 内核中禁用 appnope:

# ~/.ipython/profile_default/ipython_kernel_config.py
c.Kernel._darwin_app_nap = False
