pip - pip install pyspark 后运行 pyspark

Question

我想在我的家用计算机上安装pyspark。我做到了

pip install pyspark
pip install jupyter

两者似乎都运作良好。

但是当我尝试运行 pyspark 时，我得到了

pyspark
Could not find valid SPARK_HOME while searching ['/home/user', '/home/user/.local/bin']

SPARK_HOME 应设置为什么？

Answer 1

我刚刚遇到了同样的问题，但事实证明pip install pyspark下载的spark distirbution在本地模式下运行良好。 Pip 只是没有设置适当的 SPARK_HOME。但是当我手动设置它时，pyspark 的工作方式就像一个魅力(无需下载任何额外的包)。

$ pip3 install --user pyspark
