我正在尝试启动服务器,
但我得到这个错误

/home/ceddy/syd/sydjs/node_modules/keystone/admin/server/middleware/logError.js:7
    var msg = `[${endpoint}]`;
              ^

当我查看似乎在第7行引起错误的文件时,我没有看到任何错误,如控制台所示...
 我在这里错过了什么吗,是什么原因?
提前致谢

module.exports = function (req, res, next) {
res.logError = function logError(endpoint, description, err) {
    if (arguments.length === 2 && typeof description !== 'string') {
        err = description;
        description = null;
    }
    var msg = `[${endpoint}]`;
    msg += description ? (` ${description}:`) : ' error:';
    if (err) {
        console.log(msg, err.message, '\n' + err.stack);
    } else {
        console.log(msg);
    }
};
next();
};

最佳答案

您尝试使用的语法是新ES2015标准的一部分。确保使用支持Template Strings的节点版本

我建议至少使用节点4.2.3,因为它是LTS版本,而没有iojs,因为它已合并回节点。
