如何在我安装 Apache Spark和 PySpark的确切位置安装 Apache Toree？

如何解决如何在我安装 Apache Spark和 PySpark的确切位置安装 Apache Toree？

所以我在位置 /opt/spark/ (Ubuntu) 安装了 Spark。我正在尝试安装 Apache Toree 以便在 Jupyter 笔记本中使用 Spark。我相信 Apache Spark 和 Toree 的安装位置需要在同一个目录中，但我不能 pip install toree 进入同一个文件夹。所以我附上spark安装的目录信息-

deep@deep-VirtualBox:~$ cd /opt/spark/
deep@deep-VirtualBox:/opt/spark$ ls
bin  conf  data  examples  jars  kubernetes  LICENSE  licenses  
logs  NOTICE  python  R  README.md  RELEASE  sbin  work  yarn

和错误 -
