我正在按照here教程在AWS上进行PySpark。
我的操作系统：macOS High Sierra 10.12.6
到目前为止，一切都按教程中的方式进行。
我已经成功创建了“ hello-spark.yml”文件，并以精美的文字打开了文件，编辑的部分也在那里。
我运行以下代码时收到错误消息：
conda env create -f hello-spark.yml
myComputerName anaconda3 MyPersonalName$ conda env create -f hello-spark.yml

原始帖子按如下方式创建.yml文件：
name: hello-spark
dependencies:
- python=3.6
- jupyter
- ipython
- numpy
- numpy-base
- pandas
- py4j
- pyspark
- pytz
正确的方法是：
name: hello-spark
dependencies:
- python=3.6
- jupyter
- ipython
- numpy
- numpy-base
- pandas
- py4j
- pyspark
- pytz
如果不确定如何在vi中进行编辑，只需使用sublime文本或任何其他代码编辑器即可。
