Enmap(更好的sqlite映射)在应用程序重新启动之前不会更新

Question

这是来自我正在处理的不和谐机器人的代码片段

它需要从 Enmap 加载数据，将信息添加到该数组，然后将其推回去。

它成功地提取了数据，进行了所有转换和添加等 并成功推送该数据

但是，在程序重新启动之前，它无法提取新数据。它被保存了，但let locationDataArray = await data.get(locationDataKey);除非重新启动程序，否则似乎不会拉出这个新版本的地图

我相当难倒

const Commando = require('discord.js-commando');
const levenshtein = require('fast-levenshtein');

const Enmap = require("enmap");
const data = new Enmap({
name:"locationdata"
});
const settingsMap = new Enmap({
name:"locationSettings"
})
module.exports = class addConnection extends Commando.Command{
constructor(client){
super(client, {

}
async run(msg,args){
//get our guilds Information
let guildID = msg.guild.id;
let locationDataKey = guildID+"_mapData";
let locationDataArray = await data.get(locationDataKey);
//Our Guild Settings
let settingMapKey = guildID+"_setting";
let settings = await settingsMap.get(settingMapKey);

//chiefly out npcRoleID
let npcRole = await msg.guild.roles.get(settings.npcRoleID);
let connectionArray = await args.destinations.toLowerCase().split(",");
for(var i = 0; i < connectionArray.length; i++){
//make sure the item is valid
var distance = levenshtein.get(connectionArray[i], locationDataArray[0].name);
var closestDistance = distance;
var closestWord = locationDataArray[0].name;
for(var j = 0; j < locationDataArray.length; j++){
distance = levenshtein.get(connectionArray[i], locationDataArray[j].name);
if (distance < closestDistance){
closestDistance = distance;
closestWord = locationDataArray[j].name;
}
}
//make sure all the areas are valid and good
if(closestDistance < (closestWord.length/2)){
connectionArray[i] = closestWord;
}
else{
msg.channel.send("those channels don't seem to exist").then( msg => {
msg.delete(10000);
});
return;
}  
}
//our array of connections now only contains valid options
//loop over our location data array
for(var i = 0; i< connectionArray.length; i++){
for(var j = 0; j < locationDataArray.length; j++){
//when we hit one of out LDA that has the same name as something in the connectionArray
//stop add the rest of the connection array to its connections

let role = await msg.guild.roles.find(role => role.name === connectionArray[k]);
let currentChannel = await msg.guild.channels.find(channel => channel.name === locationDataArray[j].channelName);

//the connection can read but not type in its connection
currentChannel.overwritePermissions(

data.set(locationDataKey, locationDataArray);

我知道这个问题很老了，我希望你很久以前就解决了这个问题，但为了后代的缘故，因为人们以后可能会发现这个问题，我还是会回答它。

发生这种情况的原因是您正在此文件中创建一个新的 Enmap 实例，并且可能您也在其他文件中声明了它。这会导致为 Enmap 创建一个新的"客户端"，该"客户端"具有自己的单独缓存，并且 Enmap 无法更新这些实例。

解决方案是将 Enmap 附加到随身携带的变量(例如客户端(，或者创建一个单独的节点模块，并将其导入到任何需要的地方。Enmap 文档中对这两个选项进行了更详细的描述：https://enmap.evie.dev/usage/using-from-multiple-files
