描述：

在使用Homebrew之后，我在 MacBook 上安装了 spark 。我按照以下说明进行操作：https ://www.tutorialkart.com/apache-spark/how-to-install-spark-on-mac-os/ 。

一步一步的过程包括安装 Java，然后是 Scala，然后是 Spark。Java 和 Scala 安装成功。Spark 也安装成功。

当我尝试使用以下输入命令验证 spark 安装时，我遇到了错误。

输入指令： spark-shell

预期行为：期望 Spark 在终端上启动

实际行为：我收到以下错误： 

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 已更改为usr/local/opt/java.

我仍然收到错误消息。感谢您的回答/反馈。谢谢！！！

请按照以下步骤操作 macOS 第 1 步。安装 java 8，因为 Spark 2.2 及更高版本需要 java8。请参阅Spark 文档！详情。

酿造安装 openjdk@8

然后设置更新java路径

export JAVA_HOME=/usr/local/opt/openjdk@8/libexec/openjdk.jdk/Contents/Home

我在网上搜索并看到了安装 pyspark 的说明。

pip install pyspark我在终端上运行了这个命令

安装 pyspark 后，spark 和 pyspark 都在运行。

不知道发生了什么，但我现在可以运行 spark 了。

感谢@Elliott 的互动和指导！
