nikitapant@IND-FVFXL93UHV29 ~ % source ~/.zshrc
/Users/vaibhavkumar/.zshrc:5: /Users/vaibhavkumar/spark not found
nikitapant@IND-FVFXL93UHV29 ~ % vi ~/.zshrc
nikitapant@IND-FVFXL93UHV29 ~ % 

As this folder is available at the specified location but showing not found, not able to find any clue.

Answer 1

You need to get rid of the $ .

export SPARK_HOME=/Users/vaibhavkumar/spark

---

With the dollar sign, the undefined parameter first expands to the empty string, leaving you with

export =/Users/vaibhavkumar/spark

A word prefixed with = in zsh tries to do path lookup on that word. Since there is no file named /Users/vaibhavkumar/spark in any directory in your PATH variable, you get the observed error.
