安装后无法执行pyspark [英] unable to execute pyspark after installation

问题描述

我手动复制了 spark-2.4.0-bin-hadoop2.7.tgz 并解压缩。然后我在 .bash_profile 中输入如下：

I have manually copied the spark-2.4.0-bin-hadoop2.7.tgz and extracted. Then I have made entry in .bash_profile as below:

export SPARK_HOME = /用户/ suman / Pyspark / spark-2.4.0-bin-hadoop2.7
export PATH = $ SPARK_HOME / bin：$ PATH

export SPARK_HOME=/Users/suman/Pyspark/spark-2.4.0-bin-hadoop2.7 export PATH=$SPARK_HOME/bin:$PATH

我确定我已在下面安装 jdk.Response ：

I'm sure that i have installed jdk.Response below:

ABCDEFGH：bin suman $ java -version java version112018-09-25
Java（TM）SE运行时环境18.9（版本11 + 28）Java HotSpot（TM）

错误如下：

推荐答案

我在这里的答案中尝试了所有内容，包括karma&苏曼的答案，没有任何效果。我将此路径添加到.bash_profile并且它对我有用：

I tried everything in the answers here including karma & suman's answers and nothing worked. I added this path to .bash_profile and it worked for me:

export JAVA_HOME="/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home -v 1.8"

我希望它适合你。
