导入express-handlebars时会给出"SyntaxError:意外令牌“

Question

当我添加此行时，出现错误，如果删除，错误将消失

const expressHandleBars = require('express-handlebars');

这就是错误，

C:\Users\Hp\sample-project\node-mongodb-api\node_modules\express-handlebars\lib\express-handlebars.js:230
                                );
                                ^

您使用的是什么版本的Node.js？请查看this issue。

函数调用功能中Trailing commas导致的错误。此功能已在Node v8中实现，因此您必须将Node.js升级到8+版本才能使用express-handlebars。
