描述：
我使用Homebrew在我的MacBook上安装了spark。我遵循了以下指导过程：https://www.tutorialkart.com/apache-spark/how-to-install-spark-on-mac-os/.
这个循序渐进的过程包括安装Java，然后是Scala和Spark。Java和Scala安装成功。Spark也成功安装。
当我尝试使用下面的输入命令验证spark安装时，我遇到了一个错误。
输入命令：spark-shell
预期行为：预计Spark将在终端上启动
实际行为：我得到以下错误：
Unable to find any JVMs matching version "1.8".

我尝试了什么：
我尝试使用以下命令更改JAVA_HOME：
export JAVA_HOME=/usr/local/opt/java
以前的JAVA_HOME路径是/opt/anaconda3。我可以看到JAVA_HOME被更改为usr/local/opt/java。
我仍然会出错。感谢您的回答/反馈。谢谢
对于macOS，请执行以下步骤步骤1。安装java8，因为Spark 2.2以后的版本需要java8。请参阅Spark文档！详细信息。
brew安装openjdk@8
然后设置更新java路径
export JAVA_HOME=/usr/local/opt/openjdk@8/libexec/openjdk.jdk/Contents/Home
我在网上搜索，看到了安装pyspark的说明。
我在终端上运行了这个命令pip install pyspark
安装pyspark后，spark和pyspark都在运行。
不知道发生了什么事，但我现在已经能够点燃火花了。
感谢@Elliott的互动和指导！
