Question

我有一个ipython3 kernel.json，我想让它与系统无关，所以它看起来像这样：

{
    "argv": [
         "$SPARK_HOME/bin/spark-submit",
         "--master", "$MASTER",
....

$ SPARK_HOME / bin / spark-submit指向初始化内核的shell脚本。但是当我尝试在IPy笔记本中切换到它时，我收到了以下错误，看起来像spark-submit没有找到：

kernel.json中不支持美元符号吗？如果是真的，我该如何解决？

非常感谢您的帮助。

如何在ipython3 kernelspec中使用环境变量（NOT SET，USE）？
