当我在运行ipython终端的时候，发现报错了，错误信息如下：
wugaosheng:spark-2.2.0-bin-hadoop2.7 eric$ IPYTHON=1 IPYTHON_OPTS="--pylab" ./bin/pyspark Error in pyspark startup: IPYTHON and IPYTHON_OPTS are removed in Spark 2.0+. Remove these from the environment and set PYSPARK_DRIVER_PYTHON and PYSPARK_DRIVER_PYTHON_OPTS instead.wugaosheng
