关键字在节点红色功能节点中不起作用

关键字在节点红色功能节点中不起作用

本文介绍了'require'关键字在节点红色功能节点中不起作用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

var moment = require('moment-timezone');

var moment = require('moment-timezone');

我正在尝试为传感器数据建立时区正确的日期/时间戳。此节点运行时出现以下错误;

I am trying to establish a timezone correct date/time stamp for sensor data. I get the following error when this node runs;

ReferenceError:require未定义(第1行,第14行)

顺便说一句,这个函数还有其他一直运行良好的JavaScript。

This function, by the way, has other JavaScript which always runs perfectly.

我的Package.json没有错误,我有,moment-timezone:0.5.3补充。

My Package.json has no errors and I have the, "moment-timezone":"0.5.3" added.

我从一点或研究中了解到我需要在settings.js文件中添加一些东西,但是,我需要一些关于添加内容的指导,以便识别'require'。

I understand from a bit or research that I need to add something to the settings.js file, however, I need some guidance on what to add so that 'require' is recognized.

推荐答案

as 说明,你不能使用 require 本身在函数节点内,但您可以将外部模块添加到用于运行函数的沙箱中。您可以在 settings.js 文件中执行此设置 functionGlobalContext ,如下所示:

As this GitHub issue answer states, you cannot use require itself inside a function node, but you can add external modules to the sandbox used to run functions. You would do this setting functionGlobalContext inside your settings.js file like the following:

functionGlobalContext: {
    tzModule:require('moment-timezone')
}

然后可以使用以下代码引用该模块:

The module can then be referenced by using the following code:

var moment = global.get('tzModule');

Check out the Node-RED documentation on global-context for full details.
