I am testing a contract, when I run the truffle migrate command, in my deplyment contract located in the migrations folder the following error appears:

var HelloWorld=artifacts.require (“./HelloWorld.sol”);
                                  ^

SyntaxError: Invalid or unexpected token

I am using solidty 0.5.0, What is wrong with the syntax of the .js file.

    You have to use the symbol " (Unicode Quotation Mark U+0022) to delimit strings in javascript. Others symbols like “ (Left Double Quotation Mark U+201C) nor ” (Right Double Quotation Mark U+201D) are not accepted (yet). It is common in some pages to replace " by the later symbols because they look nicer on screen, but unfortunately that will not work for source code and it will break copy+paste examples.
