Possibly Storm cannot find JAVAHOME in your computer. Here is how to fix it.

1. Open storm_env.ini file in storm conf folder.
2. Find line that configures alternate JAVAHOME
   if you are accessing for the first time it'll look like this
   
   #The java implementation to use. If JAVA_HOME is not found we expect java to be in path #JAVA_HOME:home

3. Update it with your JAVAHOME

   ex (this how it looks in my file.):

   #The java implementation to use. If JAVA_HOME is not found we expect java to be in path

   JAVA_HOME:/usr/lib/jvm/java-8-oracle

4. Save changes and close the editor.

5. Open new terminal and try again
