我希望有人能帮助我理解为什么 JupyterLab 无法在我的系统上启动内核。
背景
我正在开发 macOS High Sierra。我曾经通过 Mac OS 安装程序在我的主文件夹 ( $HOME/anaconda) 的默认位置安装 Anaconda。基于这个线程，我卸载了 Anaconda。
我从 Homebrew Cask 重新安装了 Anaconda（放在export PATH=/usr/local/anaconda3/bin:"$PATH"我的.bashrc.
问题
现在当我
- 运行
jupyter-lab， - 创建一个新笔记本，并且
- 选择一个 Python 3 内核，
该过程失败，输出如下：

我已经从我的环境 ( , ) 中删除了对$HOME/anaconda（我的旧安装位置）的所有引用，所以我无法确定引用的位置。.bashrc.bash_profile
任何建议将不胜感激。
