设置了SPARK_HOME env变量，但是Jupyter Notebook没有看到它. (视窗) [英] The SPARK_HOME env variable is set but Jupyter Notebook doesn't see it. (Windows)

问题描述

我在Windows 10上.我试图启动Spark并在Jupyter Notebook和Python 3.5中运行.我安装了Spark的预构建版本，并设置了SPARK_HOME环境变量.我安装了findspark并运行代码:

I'm on Windows 10. I was trying to get Spark up and running in a Jupyter Notebook alongside Python 3.5. I installed a pre-built version of Spark and set the SPARK_HOME environmental variable. I installed findspark and run the code:

import findspark
findspark.init()

我收到价值错误:

ValueError:找不到Spark，请确保已设置SPARK_HOME env或Spark在预期的位置(例如，通过自制程序安装).

ValueError: Couldn't find Spark, make sure SPARK_HOME env is set or Spark is in an expected location (e.g. from homebrew installation).

但是设置了SPARK_HOME变量. 此处是一张屏幕截图，显示了我的系统.

However the SPARK_HOME variable is set. Here is a screenshot that shows that the list of environmental variables on my system.

有人遇到此问题或知道如何解决此问题吗?我只发现一个古老的讨论，其中有人将SPARK_HOME设置到错误的文件夹，但我不认为这是我的情况.

Has anyone encountered this issue or would know how to fix this? I only found an old discussion in which someone had set SPARK_HOME to the wrong folder but I don't think it's my case.

推荐答案

我遇到了同样的问题，并通过安装无用的"和虚拟的盒子"解决了. (请注意，尽管我使用的是Mac OS和Python 2.7.11)

I had same problem and had it solved by installing "vagrant" and "virtual box". (Note, though I use Mac OS and Python 2.7.11)

看一下本教程，该教程适用于哈佛CS109课程: https://github.com/cs109/2015lab8/blob/master/installing_vagrant. pdf

在终端上无用重新加载"后，我可以运行我的代码而不会出现错误. 注意附件图像中显示的命令"os.getcwd"的结果之间的差异.

After "vagrant reload" on the terminal , I am able to run my codes without errors. NOTE the difference between the result of command "os.getcwd" shown in the attached images.
