What should we do?
I don't know.

I'm glad I'm on this forum, I know exactly what you did wrong mr. 
BoQsc

I checked the documentation and it seems that, you assumed the 
wrong syntax for "environment.opIndexAssign()"

The correct syntax is:
environment.opIndexAssign("Some Random Value Here", 
"variableName");

And not this one:
environment.opIndexAssign("variableName", "Some Random Value 
Here");


Take a look at this documentation once more:
https://dlang.org/library/std/process/environment.op_index_assign.html

import std.stdio   : writeln;
import std.array   : replace;
import std.process : environment;

void main(){
	// Retrieve environment variable "path" for testing if it is 
possible
        // to retrieve it by using D language Phobos Library
        auto environmentPaths = environment.get("path");
	writeln(environmentPaths); // Works as expected: we can see the 
output of Paths.
        
	// Create a new Environement variable for testing if it is 
possible
        // to Create it with D language Phobos Library
	environment.opIndexAssign("Some Random Value Here", 
"variableName");
        auto environmentalVariable = environment.get("variableName");
	writeln(environmentalVariable); //Unexpected: absolutely no 
output.
}
