Conditional execution based on environment variable

I'm very new to puppet so forgive me if my question is stupid. I wrote a puppet script that will install 2 software packages on systems. I want to make the script install either package 1 or package 1 & 2 based on an environment variable. I have the following syntax but i'm getting an error

 if $env_variable == 1 {
      node default {class{'package1':}->class{'package2':}}

} elsif  
    $env_variable == 2 {
          node default {class{'package1':}
} 


"Error: Could not parse for environment production: Classes, definitions, and nodes may only appear at toplevel or inside other classes at site.pp:14 on node"

The script is able to view the env variable (I'm able to get the value if I do notify $env_variable) and It's also working if I don't have the if block.

Is this syntax not correct? Is it even possible to do it this way or is there another way to implement this?

Try placing a case statement inside of your default node definition and based on the value of $env_variable, declare the appropriate classes. That should work fine and follow the correct Puppet language syntax.
