为什么在我的节点生产服务器版本上而不是本地版本上出现语法错误？
[英]Why am I getting a syntax error on my node production server build but not my local build?
问题描述
I hope you can help me . 
我希望你能帮助我 。 i'm fairly new to node and am building my first node app. 我对Node相当陌生，正在构建我的第一个Node应用。
I have built out an app in node.js. 我已经在node.js中构建了一个应用程序。 It works fine and as expected when running locally. 在本地运行时，它可以正常运行并按预期运行。
When trying to run it on our internal production server I get an error message. 尝试在内部生产服务器上运行它时，出现错误消息。
It seems to take issue with the opening template literal tag. 开头模板文字标签似乎出现了问题。 The file in question employs a simple module export function. 有问题的文件使用简单的模块导出功能。 I've stripped down the code a bit to make it easier to read. 我将代码简化了一些，以使其更易于阅读。 See below: 见下文：
exports.templateModule = function(markup, edmData) { var template = `<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head></head> <body></body> </html> `; return template;
I'm using node version v6.11.0. 我正在使用节点版本v6.11.0。
The production server is running on linux. 生产服务器在Linux上运行。
package.json file below incase it helps. 下面的package.json文件可以帮助您。

"name": "template",
"version": "0.0.0",
"description": "A simple tempate test.",

"url": "https://github.com/heroku/node-js-getting-started"

Template strings were added in NodeJS v4.0.0 . 模板字符串已添加到NodeJS v4.0.0中 。
Node.js v4.0.0 contains V8 v4.5, the same version of V8 shipping with the Chrome web browser today.
This brings with it many bonuses for Node.js users, most notably a raft of new ES6 features that are enabled by default including block scoping, classes, typed arrays (Node's Buffer is now backed by Uint8Array), generators, Promises, Symbols, template strings , collections (Map, Set, etc.) and, new to V8 v4.5, arrow functions.
If you are using an older version of Node.js on your production server, please consider upgrading it to a more recent version. 如果您在生产服务器上使用的是Node.js的旧版本，请考虑将其升级到最新版本。
